The Mystery of Mamo (US) or The Secret of Mamo (International), originally released in Japan as simply Lupin III and now known there as Lupin III: Lupin vs. the Clone is a 1978 Japanese animated adventure film. It is the first animated Lupin III film release, based on the manga series of the same name created by Monkey Punch, and was produced by TMS Entertainment, directed by Sōji Yoshikawa and written by Yoshikawa and cult pink film screenwriter Atsushi Yamatoya.
The world’s most wanted master thief, Lupin the Third, is dead! Despite a coroner’s report, Interpol Inspector Zenigata is skeptical and discovers that Lupin is actually alive and well and stealing! But who had set up Lupin’s death and why?
For now, questions are set aside, as Lupin, Jigen, and Goemon immediately embark to Egypt to pilfer a stone artifact from a pyramid, with Zenigata in hot pursuit. But Fujiko, lured by the promise of eternal youth and beauty by the sinister and enigmatic scientist known as Mamo, double-crosses Lupin and steals the stone. Her betrayal causes a rift between Lupin and his cohorts, causing the trio to split up, but eventually leads Lupin to Mamo’s hideaway, where he discovers the madman’s dark secret and a fiendish scheme that threatens the entire planet! Now, it’s up to Lupin to stop the insane Mamo — before he can complete his 10,000 year-old plans of world domination.
Originally, this film was known as Lupin III. This was the name used in Japan, JAL Flights, France and Italy. After the movie The Castle of Cagliostro was released, in Japan the film was renamed as Lupin III: Lupin VS Duplicate Human (ルパン三世 ルパンVS複製人間 Rupan Sansei - Rupan VS Fukusei Ningen?) or Lupin III: Lupin VS Clone (ルパン三世 ルパンVSクローン Rupan Sansei - Rupan VS Kurōn?), translated on English websites as Lupin vs the Clone. Futabasha Action Comics had named this in their film comic adaptation Confrontation with Mamo (マモーとの対決 Mamō to no Taiketsu?).
A video tape copy was obtained from Jun Hirabayashi, former representative of TMS to Fred Patten to gauge whether anime could be marketed to the US. It was then traded onto tapes among the US anime fan circle. However, they were uncomfortable using that name as it gave away an important plot point. Mark Merlino came up with the spoiler-free title The Mystery of Mamo . When Streamline came to dub the movie due to unable to use the Toho dub, TMS had come up with The Secret of Mamo inspired by the fan nickname and wanted them to use that name.
This became an issue whether a company used Mystery or Secret. Streamline stuck with the fan name due to alliteration and the fans already knew it as that name. In Japan, Toho released a laserdisc with this dub and Lingaphone released a tape, both having "The Mystery of Mamo" name due to using the Streamline dub. Manga UK however used "Secret of Mamo" due to no fanbase and no previous release in the UK. Pioneer used "The Secret of Mamo" name and Discotek reverted back to "The Mystery of Mamo". Currently TMS USA uses this name in their promotional material. American based websites also generally use "The Mystery of Mamo".
"The Secret of Mamo" name was kept in the UK with France and Mexico receiving a translated version of the name. In Italy it was renamed to La pietra della saggezza (The stone of wisdom).
Inspector Zenigata investigates the execution of Lupin III, but discovers Lupin has used the dead body as a decoy and that he is just as confused about this other Lupin. Lupin flees from the castle via hang glider. In an Egyptian pyramid, Lupin finds Philosopher's Stone with Daisuke Jigen, but they are discovered by Zenigata and the Egyptian police. Lupin escapes the pyramid corridors and Goemon Ishikawa XIII incapacitates the officers surrounding the pyramid. The three use Lupin's Mercedes-Benz SSK to flee from the pyramid.
After Lupin delivers the stone to his lover Fujiko Mine, Fujiko turns on Lupin and steals the stone. Lupin and the others listen in on Fujiko to find out who asked for the Stone, only to discover that the Stone was a fake. Dissatisfied that Lupin had given him a fake, the contractor dispatches two of his henchmen to kill the thief. After Lupin and his gang defeat the henchmen, Flinch destroys Lupin's car and his headquarters. Jigen and Goemon suspect that Fujiko sold them out, and berate Lupin for being faithful to her until Lupin promises to drop Fujiko for good.
Crossing into Spain, the gang traverses the desert where Lupin accidentally sets off one of Flinch's booby traps before the group finds a house stocked with food and water. A seriously wounded Fujiko comes for Lupin, making him go back on his promise and alienate Jigen and Goemon. Fujiko secretly drugs Lupin's food, but doesn't realize how strong the medicine is and Lupin ends up being knocked out completely after his attempted ravishing of Fujiko goes awry. They are both captured by Flinch and shoved into his plane. Jigen fails to stop the plane, but recovers a note dropped by Fujiko. The next day, Jigen gets pursued by Gordon. Surprised at first by Jigen's quick move to threaten him, Gordon manages to bring him and Goemon to Area 64 to be interviewed by Stuckey, an important government official from America.
After listening to a tape of an interfered-with conversation between the secretary general and the U.S. president, Stuckey asks for info on Mamo, the man who broke into the conversation. Jigen claims they know nothing, but Gordon doesn't believe him. Jigen hands Gordon the note, which says "WATER," and angers him by still claiming that they know nothing. Stuckey decides that Jigen and Goemon knew nothing, releasing them for the sole purpose of using them to find the mystery man. The note lands in the spilled water, revealing the word "CARIB," which Jigen recognizes as the Caribbean.
Meanwhile, on a Caribbean island, Lupin escapes from his prison and comes across Napoleon and Hitler, much to his shock. He manages to find the mystery man, who reveals himself to be Howard Lockewood, Mamo himself. He offers Lupin eternal life, but Lupin declines, saying that nothing good comes from longevity and that all he wants is the stone. He is able to find and reclaim it as Jigen and Goemon head for the Caribbean island, unaware that Gordon and Stuckey are tracking them via spy satellite. Fujiko plays with Lupin awhile in an attempt to get him to accept Mamo's offer, but they are soon chased by thugs led by Flinch, as Lupin had discovered what Mamo's staff was planning to do with the Stone. Lupin and Fujiko end up in Mamo's lair, where he reveals that the island is inhabited by clones of famous people and that he is planning on becoming a god. Lupin doesn't believe him at all.
Mamo deems Lupin unworthy of eternal life, but Fujiko refuses to abandon Lupin. Mamo straps Lupin to his chair and reveals his dirtiest secrets to a horrified Fujiko. When Mamo tries to look into Lupin's self-conscience, however, he is shocked that Lupin doesn't dream, declaring it a trait of either a complete idiot, or a god. Mamo tries to kill him, but is interrupted when the island is bombed by the United States Air Force. Lupin is rescued by Goemon and Jigen, who puts a bullet in Mamo's head. They and Fujiko then get the hell out of Dodge, but not before Goemon engages in a final confrontation against Flinch. When Goemon learns that even his Zantetsuken couldn't penetrate Flinch's armor, he instead proceeds to cut Flinch's face, much to the latter's shock. As Flinch drops dead into the water, the tip of the Zantetsuken breaks off, much to Goemon's sorrow. As the gang leaves the island with an unconscious Lupin, they are chased by Zenigata who chooses the wrong boat to go after them in. Even so, he tries going after them on the other boat, but the boat is destroyed, however, by the USAF.
Finding Zenigata on a beach, the Commissioner reveals that Zenigata has been removed from the Lupin case as his association with Mamo has expanded the case to a global scale. He encourages Zenigata to think of it as an opportunity to take a vacation, even offering a bonus, but Zenigata instead tears up the bonus and resigns from the police force, opting to go after Lupin on his own as a private citizen.
Meanwhile, Lupin and his gang (sans Goemon, who decided to train harder) retreat to an old hotel, keeping themselves up with coffee. Jigen shows Lupin what's left of the Zantetsuken, which Lupin puts in his pocket. Lupin deduces that Mamo has been using cloning technology to achieve his desire for eternal life, which is confirmed by Mamo himself when the latter thrusts the group into a black void. Mamo reveals his hand in the history of the world, converses with Lupin regarding who was really executed, and puts the gang back where he had left them after rearranging the room a bit. Lupin is quick to figure out how Mamo managed to do it. When Mamo shows up to reclaim Fujiko, Lupin dares him to prove himself a God by performing some kind of miracle without his Las Vegas-style parlor tricks. Mamo responds by setting off several charges to simulate an earthquake, which registers on the Richter scale and alerts Gordon and Stuckey to where Mamo is located.
Lupin figures out what was behind that earthquake and sets off for the source, where he believes Mamo to be hiding. As Mamo convinces Fujiko to push a button to launch missiles, Lupin shows up as the snake to their Adam and Eve, revealing he rigged the missiles to blow up before they could launch. Frustrated, Mamo takes Fujiko with him to a rocket launching pad and tries fending Lupin off with lasers. Lupin uses the tip of Goemon's Zantetsuken to deflect the lasers onto Mamo and incinerate him, but not before Lupin learns from Mamo that he is the original Lupin and that it was the clone that swung in Transylvania. Lupin is sure that was the real Mamo until he discovers a chip hidden among the ashes.
The rocket emerges, containing a brain that reveals itself to be the original Mamo. Lupin figures out that Mamo had controlled the clones resembling his old body right before the rocket launches into space as Mamo declares he is setting off into space and eventually plans to return to Earth as its one true God. Lupin and Fujiko escape the rocket's trajectory, but not before Lupin puts an explosive onto the rocket. The glass shatters, and Mamo's gigantic brain drifts toward the sun as Lupin reminds Mamo that time does everyone in and that he should be grateful Lupin put him to death when he did. Fujiko reveals that Zenigata had threatened her into luring his quarry for the catch, and Lupin is unable to convince Zenigata that he is a clone and that the real Lupin was the one that was hanged. Fujiko offers to help Lupin after they kiss, but Gordon launches his missiles on Mamo's Colombian base, and Jigen picks up Fujiko in a plane while Zenigata and Lupin escape together on foot.

This film has been dubbed four times by four different companies: Frontier Enterprises in 1979, Streamline Pictures in 1995, Manga UK in 1996 and Geneon in 2003.
The first dub was produced by Frontier Enterprises for Japan Airlines. It has also been nicknamed the Toho dub and the JAL dub. While Lupin's name is kept intact, the other characters were renamed to make the film more accessible to international audiences: Jigen became Dan Dunn, Fujiko became Margo, Zenigata became Ed Scott and Goemon was simply Samurai. The cast list is speculated due to Frontier Enterprises not documenting its English dubbing work. Outside of Lupin, Samurai and Detective Ed Scott, where the voice actors are known, the other characters are based on voice recognition from other dubs by the company. Mamo's alias is Foward Fughes. Dan Dunn says kærɪˈbiːən during when the water was poured on the note and Lupin is pronounced either as Loopahn or Lupan depending on voice actor. The president was based off Jimmy Carter.
The dub gave the nickname "Old Man" for Inspector Koichi Zenigata that was used by fans and the Streamline and Manga dubs until the Geneon dub where it was replaced by "Pops." Though older fans still used "Old Man" for fan translations and discussions, the nickname has been overall retired from official releases and by fans.
Currently this is the only Lupin III English dub that was not done in the US or the UK. This dub is also closest to the original Japanese script with minor changes for lip syncing and character names. Parts of the dub was used in the Cliff Hanger game.
The second dub was produced by Streamline Pictures, who were unable to release the Frontier dub due to copyright reasons. It was the first film from the company that used the Lupin name as the copyright to the Arsène Lupin name had expired. All of the voice actors reprise their roles from the Streamline dub of The Castle of Cagliostro, with the exception of Steve Kramer, who voiced Goemon. Ardwight Chamberlain voices Goemon in this film, though Kramer does appear as Heinrich Gissinger.
The script was based on the Frontier dub with some rewrites and some additional dialogue to make the film more humorous and the dialogue more natural. Streamline Pictures also added extra sound effects that were not present in the original. Mamo's alias is Haward Lockewood. Jigen (who is implied to be American in this dub) says kəˈrɪbiən during when the water was poured on the note and Lupin is pronounced as luːpɪn. The president was based off Bill Clinton. This dub was also exported to Japan.
The third dub by Manga UK was created due to copyright reasons in the UK regarding the Lupin name. As a result, the Streamline Pictures dub could not be used for its VHS release, like with The Castle of Cagliostro. Lupin became Wolf the Third and Goemon had its pronunciation changed to Gomon. However, a few scenes call him Samurai or the Samurai like the Frontier dub. Like the Streamline dub, the script was based on the Frontier dub but was heavily rewritten and has additional dialogue. Some of the characters' personalities and motivations were changed as a result, especially Fujiko's. Lupin notably has different voices and tones throughout the film due to the voice direction. Jigen says kærɪˈbiːən during when the water was poured on the note.
The fourth dub was done by Phuuz for Geneon using the same cast as the English dub of Lupin the 3rd Part 2. The dub has also been referred to as the Pioneer dub, as Pioneer Entertainment released the dub on DVD. Much like Geneon's dub of Part 2, the script was heavily rewritten and received extra dialogue in scenes that the Japanese original and the previous dubs did not have to make the film more humorous. Even though the dialogue was rewritten, the names were closer to the Japanese original as it did not use the Frontier dub as a base. Mamo's alias is Howard Lockewood. Jigen says kəˈrɪbiən during when the water was poured on the note. The president was based off George W. Bush. This dub is also used for streaming services.

Like the English dub, this film has been dubbed four times by four different companies: Cinitalia Edizioni in 1979, MITO Film in 1986, LOGICA 2000 in 1993 and an unknown company in 2007.
The first dub was produced by Cinitalia edizioni on the occasion of the release in Italian cinemas, with the title Lupin III. This dub was not available on home video until it was recovered for an exhibition in Milan and has been screened in a cinema once March 21, 2009, and the audio track was recovered and digitized for the current release on DVD and Blu-ray by Yamato Video. This was based on the English Frontier Enterprises dub.
The voice of Mamo was also the voice of Jigen in the original 1979 Italian dub of Lupin the 3rd Part 1.
The second dub was produced by MITO Film for Mediaset on the occasion of the first television broadcast, with the title La pietra della saggezza and was aired on February 3, 1987. This became the future title of the film in Italy as The Castle of Cagliostro and The Legend of the Gold of Babylon were released. Unlike the other dubs, this was censored due to the network. This was also the dub that was used in the first DVD release.
The third dub was produced by Yamato Video and Logica 2000 for the home video version on VHS in 1993. It used a completely different cast compared to the animated series.
The fourth dub was created in 2007 for Mediaset. It used the English Geneon dub as a base with its liberties to its script and originally used The Secret of Mamo name rather than La pietra della saggezza. Unlike the other dubs, this was not released on home video and aired between 7th to the 12th August 2008 split into four parts on Italia 1. The dub was aired posthumously in memory of Roberto Del Giudice who had passed away in late 2007 and was one of his final works along with the Raflesia dub of The Castle of Cagliostro, Angel's Tactics and Lupin III: Lupin is dead, Zenigata is in love. This was originally aired censored as it also used the Geneon video master, later reruns were uncut. The production company is unknown however the dub was produced in Rome.

The first dub was released in 1981 by an unknown company and until the release of The Woman Called Fujiko Mine was the only time in France that the Lupin name was used before copyright issues started. The release was based of the Italian version with Planet O and the replaced credits while the scripts and the characters were based off the English Frontier dub. This dub is now considered to be lost. 
The second dub was created in 2005 by Midisync for IDP but due to copyright reasons regarding the Lupin name, Lupin was renamed to Edgar while Fujiko and Zenigata were renamed to match the dubs. The French cast of Lupin the 3rd Part 1 were used. Since 2012 the Lupin name can be used and was used in a theatrical run in December 2019 however the dub retains the Edgar name.
The Japanese release was handled by Toho, who was also responsible for the initial English dub, also known as the JAL dub or the "HK dub" produced in 1979, and was shown on JAL flights. The English dub was also released to markets in Europe such as the Netherlands and Sweden, and was also screened at least once theatrically in the United States.
The second English dub was handled by Streamline Pictures and renamed to The Mystery of Mamo, was released to home video by Orion Home Video in late April 1995 and later released on DVD by Image Entertainment in 1998. The third English dub was created due to copyright reasons and released on home video in the UK by Manga Entertainment, Ltd. in 1996 and renamed Secret of Mamo. The fourth dub was created by Fuse Entertainment and released to DVD by Pioneer Entertainment (now Geneon Universal Entertainment) in 2003 as The Secret of Mamo. This release was duplicated for Madman Entertainment's DVD release for Australia and New Zealand, and for Manga Entertainment's DVD release for the UK.
In 2012, TMS Entertainment began streaming the Geneon dub of the movie on Hulu that was later removed. In 2013, Discotek Media released The Mystery of Mamo on DVD in the US on February 26, 2013 with all four English dubs, including a reconstruction of the 1978 English dub. The reconstruction was based on an Italian DVD that had a cut version of the dub as a bonus feature and bootleg copies that originally came from the TMS tape. Discotek has announced that a Blu-ray release will be available in March 2022, and will retain all four English dubs, with new restorations for the Frontier and Manga dubs.
The film returned to Japanese cinemas for a MX4D release in 2017 and remixed the soundtrack. In 2019, a 4K Blu-ray was released by VAP and was one of the first anime releases to be released in the format. The picture was darkened and applied heavy DVNR to remove the noise. This release got mixed reviews receiving praise from Japanese reviewers and was heavily criticized in the US.

- The scene where Gordon and Stuckey discuss Mamo's earthquake (in which Stuckey has a comic book that contains an advert that features Lupin with the Justice League) was cut in the Geneon US release, as well as the Manga UK DVD. This scene was restored on the Discotek DVD as well as streaming services that featured the dub.
The Mediaset 1986 TV dub was censored however it is currently unknown what scenes were removed.
- Production on the film took fifteen months and started when Lupin the 3rd Part 2 had begun airing.
- A total of 62,000 cell sheets were used.
- There were 575 storyboard pages.
- There were 196 character design sheets for this movie.
- There were 1,315 people in the staff.
- This was Telecom Animation Film's first credited project however the entire animating team of 40 animators were considered useless frustrating Yasuo Otsuka as well as Yuzo Aoki and Yoshio Kabashima from TMS.

- Mamo's voice actor, Ko Nishimura performed his role in a deep masculine voice to contrast with Mamo's miniature appearance. This was a deliberate decision made to astonish the audience, who would hear only Mamo's voice in the first part of the film and would only later see him appear in person. This effect was replicated by voice actor Robert Axelrod in the English Streamline dub, and later by Paul St. Peter for the Geneon dub.
- This film holds the record for being the only Lupin III anime to be dubbed more times than any other Lupin related anime in both English and Italian with both having four dubs.
- Some sites have incorrectly claimed that this film has had the most English dubs made for an anime. This record belongs to the Dragon Ball series, with the first five episodes being dubbed at least six times, and the film Dragon Ball Z: The Tree of Might being dubbed at least five times.
- This was the first Lupin III anime to ever be dubbed into English and, until late 1995, the only English use of the Lupin III name due to copyright reasons.
- The Frontier dub names have made it to the original French dub that in turn, Margot was used in the Italian dub of Lupin the 3rd Part 2. Dan Dunn and Samurai were later used in the English subtitled print of The Castle of Cagliostro, while Ed Scott became Ed Cott by mistake and Margo became Rosalie.
- In the Streamline dub, Mamo threatens the President, who is supposed to be Bill Clinton, with information about the "floozy" in his steno pool. The dub's script, written by Ardwight Chamberlain, was likely written at the time when rumors around the Clinton-Lewinsky scandal were starting to circulate. Although strangely, the dub was released in April 1995, Lewinsky began work in Leon E. Panetta's office in June of that year, and confessed her affair to Linda Tripp in November 1995.
- In the Geneon dub, Lupin echoes Fujiko's line "Kiss me, my love" when she rejects immortality for a life with him.
- The US Streamline VHS release uses a painting done by Monkey Punch as its cover that was used that Fred Patten bought it himself. It was also used in a preview of The Castle of Cagliostro as it was done during the pre production phase.
- The poster used for the original showings for the Japanese, Italian and French releases as well as later Italian reprints of the Planet O record was done by Monkey Punch. It is the only Lupin III movie that had a cover in his style rather than the animated style.
- Mamo was meant to be Mameux however it was translated from French to Japanese resulting in that name. While TMS wanted to correct the name, the fandom was already used to Mamo and was kept. The Italian dubs use Mamoo.
- Jigen fires his gun only three times in this film.
- This was Monkey Punch's favorite Lupin movie. When he passed away, Nippon Television had aired the film in his memory on Friday, April 19 2019 at 9:00 p.m as part of the Friday Road SHOW!.
- This version has a different ending credits sequence, with clips from the film being played to an even shorter version of the Lupin Ondo. A memoriam to Monkey Punch appears post-credits.
- This was the last time where Zenigata's full name was Inspector Heiji Zenigata VII. In his later anime appearances it was established that his full name was Inspector Koichi Zenigata rather than sharing the same name as his ancestor. This was due to a typo in a book about Part II. The author had intended to write Zenigata's name as Heiichi, but wrote Koichi by mistake.
- When Lupin salutes to Adolf Hitler, only the Japanese original and the Toho English dub have played straight with the scene. The other dubs decide to change the dialogue by calling him "mein Führer" (Streamline and Geneon dubs) or "Schicklgruber" (Manga dub). It is also the only appearance of Hitler that wasn't Lupin in disguise or a reference.
- The name "Schicklgruber" originally belonged to Alois Schicklgruber, Hitler's father, and Maria Schicklgruber, his grandmother.
- This was the only time that Zenigata is mentioned to have a daughter called Toshiko. This was retconned by the 100th episode of Lupin the 3rd Part 2. Later Lupin media such as Part III would follow through with this retcon. Only the Japanese original and the English Geneon dub mention her name. The English Manga dub removed this line and replaced it with "his wife suing for a divorce".
- Lupin mentions to Mamo, "I'm so sick of this trick with reinforced glass." This is a reference to Part 1 Episode 2, where Pycal performs the same trick.
- This is one of the two times when Jigen smokes Pall Mall cigarettes since in Part 2 and Part 5, he smokes Marlboro Reds, and in Fujiko Mine's Lie, he smoked Lark with Lupin.
- The "Tele-Pach" orange rock candies that Lupin was seen eating are an actual product similar to Pop Rocks. Yasuo Yamada was the announcer for the Tele-Pach TV commercials during the 70's.
- Shatner Nishida who wrote Part 5 Episode 20 and Prison of the Past watches this film once a week.
- Other Lupin animations have Zenigata secretly wishing Lupin to be alive when he appears to have died, and being relieved and happy for him to be alive. In The Mystery of Mamo, this does not seem the case; he gleefully runs a stake through what he thinks is Lupin's corpse, only to find to his displeasure that it's an exploding dummy, and declares to an escaping Lupin, "If you don't die, I don't die, either! This isn't over yet! I will follow you to the pits of Hell. I will carve your posthumous name on your bones with my own hand!". The English dubs vary on whether Zenigata wants Lupin dead or alive, with the Frontier dub wanting him dead like the original Japanese dub.
- The Streamline dub implies that Jigen is American. Though this has been unconfirmed, Jigen has also shown hints of this in the Japanese versions of other Lupin animations, where he is partial to American food.
- Similarly, the Geneon dub suggests Jigen is a Republican, likely because he wouldn't agree with the Democratic Party's stance on gun control.
- The Streamline dub has Jigen mentioning the Cold War is over, which creates a plot hole. If the Cold War were over by this time, the Lupin clone wouldn't have been hanged in Transylvania. Romania abolished the death penalty as part of its post-Communist constitution in 1989.
- The Geneon dub has the movie's events take place over a year after the Lupin clone is hanged, since Zenigata mentions to Lupin the reports that the latter was executed "last spring".
- A line from Zenigata in the Geneon dub suggests that he'd been lost for a week after the US military airstrike, which also indicates the length of time Lupin was unconscious after Mamo probed his brain and then tried to kill him.
- The Streamline dub has an older Mamo clone confessing that each initial clone has barely noticeable anomalies. This line was worked into the Geneon dub as well.
- A scene that showed Zenigata working at a temple and bursting out of it when he hears Lupin is still alive was cut from the film, but featured in the trailer.
