It's my time to land on a werewolf, however, these creatures aren't "werewolves," per se. The Gallier clan from Paul Schrader's remake of Cat People (1982). They turn into leopards instead of wolves. I was going to pick James Spader from Wolf, but that movie never really gels. Cat People I haven't seen in over 30 years, but it's one of those movies my sisters made me watch when I was really little (along with The Exorcist) and it scared the bejesus out of me.
