Get Mean (1976)

In this utterly bizarre spaghetti western, the "Stranger" must cope with a wide assortment of strange villains. Through the course of the story he fights with Vikings who suddenly appear in a western ghost town; a strange Elizabethan family costumed in period clothing who live in a desert castle; and medieval knights whom he battles using machine guns, TNT, and his gun. A bizarre silver ball hangs over the melees, watching the strange goings on.
