- Currently this is the only special and animation where Lupin wears a black jacket, even though he also wears his red jacket. He previously also wore a black jacket in the 2014 live-action movie.
- It is also the only TV special where Lupin wears his red jacket with a lavender tie like Part 2 rather than a yellow tie like most specials. Prison of the Past reverts back to the yellow tie.
- Concept art of the characters lists the TV Special as "Lupin the IIIrd TVSP 2018". Lupin, Jigen and Goemon had their designs finalized in 2019 while Lupin's caped suit, Alisa Cartwright, Roy Forest and a black haired Fujiko were in 2018.
- The Frédéric Chopin songs that are played are "Tristesse" and "Revolutionary Etude" (Op 10, No. 12).
- Emilka plays a role similar to the Red Queen from the Resident Evil movies.
- Even though the US Blu-ray release of Goodbye Partner was meant to be June 30, people received copies as early as May 26. 
- It is the only known dub where an English dub was produced before the Italian dub as the release date of the English dub of The Mystery of Mamo is unknown as they were both in 1979.
