Other mistake: After the "fat fat fatty" scene, Franz shoots his way in, starting with three bullets into the door lock. Over the next scene he fires about twelve shots, despite the fact he's firing an 8-shot Luger.

Plot summary
Directed by: Mel Brooks
Starring: Gene Wilder, Kenneth Mars, Dick Shawn, Zero Mostel
Mild-mannered accountant Leo Bloom (Gene Wilder) goes to do the accounts of Max Bialystock (Zero Mostel), a failing Broadway producer. When Leo realises that if you were really a dishonest person, you could make more money with a play that flopped than you could with a hit, Max persuades him to become his business partner, and they seek out the worst play in existence, to try and get a sure-fire flop and become rich. The play they find is 'Springtime for Hitler', by an unreformed Nazi called Franz Liebkind. Having secured the play, they hire the worst director they can find, and the worst actors, including a hippy called LSD, who wanders into the audition by mistake and ends up cast as Hitler. Surely nothing can go wrong with their scheme?

Trivia: Although Mel Brooks wrote the film's musical numbers, he isn't music literate. He hummed the songs into a tape recorder, and the music was transcribed by a professional musician.
