Principal filming took place in a ravine near the Las Virgenes Creek in Malibu Creek State Park in Agoura Hills, California. This was formerly the Fox Ranch, which was owned by 20th Century Fox from 1946 to 1974, and was the shooting location for many well-known movies and TV shows. Shooting locations for M*A*S*H (1972), Planet of the Apes (1968), Butch Cassidy and the Sundance Kid (1969) and Pleasantville (1998) could all be found within a two-mile radius.
