Director Lesley Selander would make Arizona Bushwhackers (1968) three years later, narrated by a (semi) retired James Cagney. In this movie, Cagney's sister, Jeanne Cagney, plays the tough restaurant owner. He did the narration on "Bushwhackers" as a favor to A.C. Lyles, the producer of both this film and "Bushwhackers", who was a longtime friend. Pat O'Brien, also a longtime friend of both Cagney and Lyles, is also in this film.
Both Terry Moore and Bruce Cabot (the ingenue and the villain) are best known for starring in the two most famous giant ape movies ever made, and both had the same director and producer: Moore for Mighty Joe Young (1949) and Cabot for King Kong (1933).
