Vengeance is directed by Italian horror-maestro Antonio Margheriti, and it proves that he can direct a good western as well.
The hero is a Django-like character named Rocco. Richard Harrison does a fine job in this role. The showdowns between Rocco and the various men he is seeking to kill are suspenseful, entertaining, and very well done, especially the beer glass duel with the character named "Kid" (which I had to watch a couple of times to figure out how "Kid" was cheating).
In the end, it is Claudio Camaso as the main villain "Mendoza" who steals the show. Mendoza is a wonderful character who is kind of a cross between Malcolm McDowell's character in "A Clockwork Orange," and a villain you would see in the Batman TV series from the 1960's. You've gotta love it! It's the American west as it can only happen in Italy, and it is a joy to watch. The music is also great.
Highly recommended to anyone who understands and appreciates the Italian westerns.
