A nerdy college guy steals the keys to his step father's (Richard Tyson) secluded cabin so he can take up some "friends", who belong to the fraternity he wants to join. They bring along their girlfriends and he brings along a female friend he's secretly interested in. But there's a good reason the step father doesn't let anyone up there. Every full moon he goes there to let loose and transform into a rampaging werewolf. Because the college students are up there, they are only so much fresh meat. The nerdy college guy and his girl friend escape but have the rest of the movie to figure out what they are going to do to stop the monster.
The coolest thing about the movie is that the werewolf stays in character the entire movie, whether he's man or beast. When he's transformed into the monster he still talks and utters the appropriate wisecracks. In one scene after he wakes up in human form after a feeding, he takes an uneaten human finger out of his mouth, thinks about it a moment, and then finishes it.
BIG BAD WOLF is one of the best werewolf movies I have seen (and I've seen about every one) and actor Richard Tyson (TWO MOON JUNCTION, THREE O'CLOCK HIGH) gives one of his best performances to date. Tyson makes this movie work. In fact, if the producers ever decide to make a sequel they'd have to definitely bring his character back.
