The Valley of Gwangi is a 1969 American western fantasy film, produced by Charles H. Schneer and Ray Harryhausen, directed by Jim O’Connolly, written by William Bast, and starring James Franciscus, Richard Carlson, and Gila Golan. Creature stop-motion effects were by Harryhausen, the last dinosaur-themed film that he animated. He had inherited the film project from his mentor Willis O’Brien, responsible for the effects in the original King Kong (1933). O’Brien had planned to make The Valley of Gwangi decades earlier but died in 1962 before it could be realized.
