When his career started to wane stateside, Edd "Kookie" Byrnes went to Europe and starred in several spaghetti westerns, including this one. I've seen several of Byrnes' spaghetti westerns, including this one, and in all of them he seems to be out of place. He looks too clean-cut to be stuck in the grittiness of the spaghetti western world. Still, he does give it his all, rolling around in the dirt and giving it his all.
As for the rest of the movie, it has its ups and downs. It has a great musical score by Francesco DeMasi, very memorable despite a lot of it being repeated as the movie runs. There are also some serviceable action sequences, which is fortunate because the parts of the movie between these action sequences is kind of slow and lacking plot and character development.
If you like spaghetti westerns, give this movie a go. If not, look for another movie.
