This episode's release on DVD was delayed due to concerns that the treatment of Nazis right off the bat could damage future releases of the TV series. It was released on DVD volume 5.
The episode's English dub title, "To Be or Nazi Be" is a riff on both versions of the movie "To Be or Not to Be," by Ernst Lubisch: Lubisch's own 1942 film and the 1983 remake by Mel Brooks. Both films involved a troupe of Polish actors who dressed up as Nazis to make fools of the Nazi military government. This included one character dressing up as Hitler, as Lupin did in this episode.
Doing the Nazi version of a Roman salute has been a criminal offense in Germany, Austria, the Czech Republic, Slovakia, and Poland since the end of World War II, so in a realistic case Zenigata would have been charged for it whether he knew it was offensive or not.
After the tanks arrive on the film set, Zenigata mentions "doing it the Japanese way" in the original and the Italian dub, while in the English dub, he claims to be of the Allied Forces. Ironically, the Japanese were part of the Axis.
In the English dub, the gang comments on how ironic it is that Genhalter is living in Soviet-occupied East Berlin, and Lupin remarks how the former SS officer acknowledged the Stasi are "fellow homicidal totalitarians", despite being "Commies". In the early days of the Third Reich, the Nazis won over public support by advertising themselves as an alternative to Bolshevism.
