Movie Crazy (1932)

Due to a clerical error, Harold (Harold Lloyd), a bumbling small-town chap with Hollywood dreams, is invited to a film audition in Los Angeles. His screen test is a disaster, but he's hired as a film extra. He begins a romance with actress Mary (Constance Cummings), not recognizing her as the "Spanish Lady," the heavily-costumed female lead in the movie he's in. On set, Mary uses her sultry alter ego to toy with Harold, who becomes so flustered that he blunders his way to comic stardom.
