Ursus, il terrore dei kirghisi (original title)
Direction: Antonio Margheriti (as Anthony Dawson), Ruggero Deodato (uncredited)
Actors: Reg Park, Mireille Granelli, Ettore Manni
The mighty Ursus is given a potion to drink that transforms him on certain nights into a murderous werewolf. Ursus kills several innocent people in the forest in this unusual film before realizing that he himself is the creature the local villagers are seeking to destroy. Ursus is referred to as Hercules in the English-dubbed prints.
The film is filled with a variety of horrific themes and elements, featuring a killer werewolf, and is as much a horror film as it is a peplum.
