Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
This is a very low-grade B-movie western, but fortunately it's less than an hour long and it has a Gila Monster in it. A dozen white men disguised as Indians kill a man and his wife and steal all their gold but leave their two young boys alive. Ten years later one of the boys is the Sheriff and the other is a crazy killer who wears a rawhide mask and is called "The Rawhide Terror." He's also called "The Rawhide Killer," and "The Rawhide Devil," as if they hadn't figured out the movie's title yet when they filmed it. His goal is to kill all twelve of the men who killed his parents, so it's hard not to root for him even though he seems to be a homicidal maniac. When we first see him, he is holding a Gila Monster suspended by rawhide strips tied to each end of the lizard. With a wild look in his eyes he says: "You're a demon, ha? You're the most poisonous animal of the desert. Your victims die a slow death." Then he laughs an evil laugh and puts the lizard down, twisting it onto its side with the strings. I was hoping that we'd see him use the lizard's "poison" later in his revenge killing, but no such luck. It's not clear exactly what he was doing with the lizard, but he was probably torturing it or killing it to show us how crazy and how fearless he is that he can conquer such a deadly animal.
The Gila Monster looks like a real one, but it does not move at all so it was probably killed or chilled down severely before its use in the scene.
