The Producers (1967)

Continuity mistake: In the scene where Max and Leo visit Roger DeBris, Karman Ghia instructs them to remove their shoes because of the white carpet, and they do so. In the next scene, Max and Leo sit down and you can clearly see they have their shoes on. (00:42:25)

Play Actor: Don't be stupid, be a smartie! Come and join the Nazi Party!

Trivia: During "Springtime for Hitler," film director Mel Brooks can be heard saying "Don't be stupid, be a smarty! Come and join the Nazi party!" He later dubbed the same line in the 2005 version.
