Werewolf, The (1956, U.S.A.)

A stranger shows up in town, not knowing who he is or where he came from. When a local tough guy threatens him, the stranger’s anger comes out.  He turns into one of the most terrifying creatures of legend — the werewolf — killing the hooligan. As locals try to understand the unusual murder, we learn the origin of the werewolf, created by two diabolical doctors who gave the stranger an unusual serum. Meanwhile, the part-man, part-beast hides in the woods, trying not to let his curse hurt others.
