Check out Diane Venora, before she got weird and scary looking like Jessica Lange. Wolfen offers an interesting spin on the werewolf movie (these ones have ESP and can (perhaps) shapeshift at will), but it's got one too many negativized tracking shots and a few too many male frontal nudity glimpses to merit classic status. Albert Finney is exceptional, though, as a NYC detective who doesn't believe any of it and who desperately needs a haircut. Falls apart, alas, in the end.
