Movie Maniacs (1936)

The Stooges arrive in Hollywood hoping to make it in the movie business ("There must be a couple a hundred guys in Hollywood who don't know anything about making movies, three more ain't gonna make any difference".) They sneak into a movie studio where they are mistaken for three new executives who were due to arrive. After taking over production of a movie, causing the director and cast to walk off, Moe takes over as director, with Larry and Curley as the leading man and lady. When the real executives send a telegram explaining why they haven't arrived, the Stooges must leave on the run.—Mitch Shapiro
