The last twenty minutes were cut from the movie and re-shot half a year after the original shoot. Several new endings were discussed closely with producer Bernd Eichinger, including an ending in which Konrad, now a bad-ass zombie, joins a biker gang. The original ending can be found on both the German and the English DVD.
Director Matthias Dinter asked Tim Wilde to play the part of Stalin with R. Lee Ermey's Gunnery Sergeant Hartman from Cara de guerra (1987) in mind.
The fat suit used for Thomas Schmieder in the scene where he eats Stalin was also used for Detlev Buck in Berlin blues (2003).
The CD that Wurst destroys when he shoots Philip is by a band called Suco e Sol. Collien Ulmen-Fernandes was once a member of that band.
The names on the blood bottles are all names of crew members.
