An edited and censored version was also released alongside the uncut version in the US, the cut version was also accidentally featured in copies of Lupin the 3rd: Movie Pack - First Haul. Nearly five minutes were removed compared to the uncut version and claims that it was edited for television however it was not aired on TV in the US. The run time of the censored version is 1:27:39 while the uncut version was 1:31:21. Due to a bug, there are no subtitles in the edited version despite technically having the option.

Similar to the Italian censorship, in the edited version Sadachiyo has some lines removed due to that the character is gay however the character still appears in selected scenes.

All of the run times mentioned below unless mentioned are from the original version:

  • 6:33-6:57 - Lupin sits down and talks to a woman who holds his hands as he wants a traveling companion, then Lupin wants to kiss her. The cut version goes straight to Zenigata wanting to arrest Lupin.
  • 16:15-17:31 - The scene where Fujiko removes her clothes as she wanted to know why Lupin went to Morocco as they attempt to have sex. Then Sadachiyo broke in, Fujiko screamed and Sadachiyo whipped the blanket off revealing Fujiko to be naked as they both wonder what happened to Lupin was heavily cut down.

In the edited version, the only parts that were kept in were Lupin and Fujiko being in the sheets, Sadachiyo and the soldiers being by the door, Sadachiyo breaking in while Fujiko screamed and only Sadachiyo asking where Lupin ran off to.

  • 53:15-54:34 - When Sadachiyo uses the whip to strip Fujiko's clothes off and Jean-Pierre saying that Lupin has half of the diamond as Fujiko was willing to share the treasure 50/50 was cut down. The only parts that survived were most of Jean-Pierre's words outside of him saying that Fujiko is willing to betray Lupin and surprisingly saying to Sadachiyo that Fujiko can be tortured while enjoying the thought. Fujiko saying "I bet" was changed to a shot of Sadachiyo instead of her having her breasts out.
  • 1:08:03-1:08:05 (1:05:31-1:05:33) - "Is this Heaven or Hell?" was changed to "Am I dead? Oh no." due to religious reasons.
  • 1:08:50-1:10:02 - In the edited version, the scene where Lara takes her clothes off and goes to the pond was cut. Since the next part was an important scene due to half of the Twilight Gemini diamond being on her, a bra and panties was put on Lara rather than being naked like the original. The Discotek Blu-ray release recreates the edit since TMS does not have the master of the edited version as it was done by Funimation themselves. According to the credits Byron Watson, Aaron Davidson and Carly Hunter were responsible for the animated censorship.

Note: Due to Fandom policy, the wiki is not allowed to show the uncensored version of this scene.

The UK only got the uncut version on DVD.


In the Mediaset TV version as well as the Italian VHS release, all the references to Sadachiyo were censored because in the original, the character was gay.

  • According to Hideki Mitsui who wrote the script for the episode, Nippon Television wanted to have a character who could surpass Clarisse de Cagliostro. [1] The idea of Lupin going into Morocco was inspired by the Arsène Lupin story The Teeth of the Tiger[2].The original plan was Don Dalune to be in reality Arsène Lupin a reference to how he was in the original book and Lara was his grand-daughter however NTV were aware of the copyright issues regarding the Lupin name since it would have been exported as Cliff Hanger: The Secret of Twilight Gemini at the time and told him that Lupin III cannot be connected to Arsène Lupin. [3].The final script only has a slight hint.
  • The Funimation release changes the credits by shrinking the original credits into a smaller window while translating the credits at the bottom and the English credits on the side. During the credits, there is a purple right border on the animation that was not in the other masters. It also adds a "Lupin III Special Part 8" title card at the end of the TV Special.
  • In the English dub, Kyle Hebert does voice similar to a high pitched Droopy for Cali.
