Gila el monstruo gigante

The voice heard on the other end of the phone, when Chase eavesdrops on a phone call to the police department, is that of Ken Curtis, who served as producer on this film. He is more famous for having played scruffy deputy Festus Hagen on La ley del revólver (1955).

Chase is seen taking white wall tires off a wrecked car and putting them on his own. In the next scene, he has black wall tires on his car. The white wall tires change back and forth several times from scene to scene after that. (additional info) During the making of the film, several times Chase's car broke an axle. It was common for this car because of its high speed. Also due to rough country roads. This may be why the frequent tire changes noticed in the movie.

The title "The GIANT GILA MONSTER" is printed in letters covered with reptile scales
