Tarzan the Ape Man is a 1932 pre-Code American action adventure film released by Metro-Goldwyn-Mayer featuring Edgar Rice Burroughs' famous jungle hero Tarzan and starring Johnny Weissmuller, Neil Hamilton, C. Aubrey Smith and Maureen O'Sullivan. It was Weissmuller's first of 12 Tarzan films. O'Sullivan played Jane in six features between 1932 and 1942. The film is loosely based on Burroughs' 1912 novel Tarzan of the Apes, with the dialogue written by Ivor Novello. The film was directed by W.S. Van Dyke. Metro-Goldwyn-Mayer released two remakes of Tarzan, the Ape Man in 1959 and in 1981, but each was a different adaptation of Rice Burroughs' novel. It is also the first appearance of Tarzan's famous yell.
