Beast of the Yellow Night 1970
Filipino monster mess about a lecherous American soldier (John Ashley, no stranger to Filipino horror films) who saves his miserable hide during World War II by selling his soul to Satan. Everything works out fine until some years later, when Ashley tries to back out on the arrangement and is subsequently slapped with a werewolf-type curse that has him sprouting hair in unwanted places and stalking villagers by night. The werewolf attacks are remarkably gory ? throats are ripped, faces pulverized, and intestines spilled.
