Four episodes turned into five, then eight, then he was a permanent character. These days he sometimes guest stars in either Buffy or Angel. As for playing a werewolf Seth Green says, "They take their monsters pretty seriously without the show taking itself too seriously." And the transformation? "It takes a lot of time and it's really difficult to stand still," says Green. "It starts at 11:30am until 4:30pm They have to hand lay all of the hair on me, but the make-up artists there are so great, so sweet and considerate. They make it as painless as possible and the end result is worth the effect." In his spare time, Seth Green reads magazines, plays pool and sees movies.
