You never think of Westerns when you think of Vincent Price, but he was in a couple. The one I've seen was More Dead Than Alive, in which he played a Wild West Show owner who hires ex-convict Clint Walker as his main attraction. Of course, he was always better known for mystery and horror movies. One movie I really like him in is His Kind of Woman, where he plays a ham actor (spoofing himself, maybe?).
