The movie you are thinking of is "Inglourious Basterds" directed by Quentin Tarantino. It follows a group of Jewish soldiers led by Lt. Aldo Raine as they plan to assassinate high-ranking Nazi officials during World War II. Another subplot of the film follows a young Jewish woman who seeks revenge on the Nazis who killed her family.

The movie you are referring to is "The Producers," directed by Mel Brooks. It follows two men, a down-and-out Broadway producer and a neurotic accountant, who scheme to make money by producing a surefire Broadway flop. They intentionally produce a musical called "Springtime for Hitler," which is meant to offend audiences and close on opening night. However, the plan backfires when the intentionally bad show becomes a surprise hit.
