Escape from the Planet of the Apes is a 1971 science fiction film directed by Don Taylor and written by Paul Dehn. It stars Roddy McDowall, Kim Hunter, Bradford Dillman and Ricardo Montalbán. It is the third of five films in the original Planet of the Apes series produced by Arthur P. Jacobs, the second being Beneath the Planet of the Apes (1970). Its plot centers on many social issues of the day including scientific experimentation on animals, nuclear war and government intrusion. The preceding film, Beneath the Planet of the Apes, ends with the apes' future Earth being destroyed by a nuclear weapon. Escape from the Planet of the Apes begins by establishing that three apes—Cornelius (Roddy McDowall), Zira (Kim Hunter), and Dr. Milo (Sal Mineo)—escaped the Earth's destruction by salvaging and repairing Taylor's spaceship and piloting it through the shock wave of Earth's destruction, sending the ship through a time warp. The salvage, repair and launch all happen off-camera during the final act of the previous film. The apes arrive on Earth in 1973, splashing down off the Pacific coast of the United States.
