The Producers is a 1967 American satirical comedy film written and directed by Mel Brooks and starring Zero Mostel, Gene Wilder, Dick Shawn, and Kenneth Mars. The film was Brooks's directorial debut, and he won an Academy Award for Best Original Screenplay.
After reading many bad plays, the partners find the obvious choice for their scheme: Springtime for Hitler: A Gay Romp with Adolf and Eva at Berchtesgaden. It is "a love letter to Hitler" written in total sincerity by deranged ex-Nazi Franz Liebkind (Kenneth Mars). Max and Leo persuade Liebkind to sign over the stage rights.
Max sells 25,000% of the play to his regular investors.
The result of all this is a cheerfully upbeat and utterly tasteless musical play purporting to be about the happy home life of a brutal dictator. It opens with a lavish production of the title song, "Springtime for Hitler," After seeing the audience's dumbfounded disbelief, Max and Leo, confident that the play will be a flop, go to a bar across the street to celebrate and get drunk. Unbeknownst to them, the audience ends up finding L.S.D.'s beatnik-like portrayal (and constant misinterpretations of the story) hilarious and misinterprets the production as a satire.
Springtime For Hitler is declared a smash hit, which means, of course, that the investors will be expecting a larger financial return than can be paid out, which leads to Max angrily confronting De Bris, blaming him for the play being a hit.
Max laments, “I was so careful... I picked the wrong play, the wrong director, the wrong cast... where did I go right?”
