One of the lowest-budgeted films ever shot in CinemaScope and De Luxe color.
The film's premiere was planned for Lancaster, Pennsylvania, an Amish community, but the town's prudish mayor, Kendig Bare, refused to permit the screening because he considered the film too violent and sexy.
In his autobiography, Ernest Borgnine reports that during filming, Richard Fleischer asked Victor Mature to do a stunt which entailed diving underneath a car. Even with a hole in the ground, Mature refused because he had once done a scene and broke his leg on a motorcycle for which he wasn't compensated.
Victor Mature and Richard Egan, close friends in this movie, had just played mortal enemies the previous year in Demetrius and the Gladiators (1954).
