Franz Liebkind is a character from Mel Brooks' master-piece musical comedy The Producers. He is a Neo-Nazi who worships Adolf Hitler almost blindly and will try to kill anyone who makes a fool out of his beloved Fuhrur. He is not so much a villain at the start of the film but later becomes aggressive and tries to kill the main characters Max Bialystock and Leo Bloom, and two other characters after they insult Hitler in front of him. He was portrayed by Kenneth Mars in the 1968 film and by Will Ferrell in the 2005 film.
