The Perils of Pauline (1947)

Pearl White (Betty Hutton), a beautiful but talentless sweatshop girl, wins a spot in a theater company run by Michael Farrington (John Lund), with whom she becomes involved. But after a dispute with Mike, Pearl quits, hoping to try her luck in movies. When a film director humiliates her best friend, however, Pearl wreaks havoc all over the studio lot. Surprisingly, Pearl's rampage earns her the lead in an upcoming silent action movie. Soon, Pearl is on a collision course with fame.
