From: The Producers (1968 / 2005)
Mel Brooks originally wanted The Producers to be called Springtime For Hitler after the musical (and song) contained within it, but, in a moment of beautiful irony, the film’s producer at Embassy Pictures did not let him. It was a sound decision for a number of reasons. Traditionally, movies with the word ‘Hitler’ in the title don’t do that well, and it also kept the soon-to-be-infamous song and dance number under wraps before gasping cinemagoers got to see it for themselves. As for the 2005 remake… well, the Nazi pigeon was out of the bag by then.
