Remember the old Godzilla movies where every monster would show up and either fight with or against Godzilla? This western has the same idea. In this movie, Pat Garrett, Buffalo Bill, Bat Masterson and Wyatt Earp go up against Butch Cassidy and the Sundance Kid. Was Wild Bill Hickcock and Doc Holliday busy that day? Standard Western except that the humor is strangely lacking in this movie. Malcom Atterbury as Buffalo Bill is supposed to be the comic sidekick but he doesn't provide a whole lot of laughs. I am most likely reading way too much into this but when George Montgomery's Pat Garrett is giving his big speech to the town leaders about how it is their duty to stop Butch Cassidy because he will eventually destroy their town, I kept thinking about the arguments used for the Vietnam buildup, which happened a few years after this movie was made. I doubt director Fred Sears planned the similarity but if he did it was very subtle and clever. Hard to believe that Russell Johnson (the Professor on Gilligan's Island!) was the ruthless Sundance Kid. Fans of B-westerns should enjoy this movie.
