Olympic gold medal winner Johnny Weissmuller, star of a dozen Tarzan movies, including 1934's Tarzan and His Mate which featured Maureen O'Sullivan's infamous nude swimming scene. (O'Sullivan was actually doubled by Olympic swimmer Josephine McKim.)
"How can a guy climb trees, say 'Me, Tarzan, you, Jane,' and make a million?" Weissmuller later said. "The public forgives my acting because they know I was an athlete. They know I wasn't make-believe."
