The 'Teen Wolf' cast stars in Charlie Brown Halloween horror-fest

We wouldn't normally classify Charlie Brown and his comrades as, you know, terrifying, but if there's anything MTV's "Teen Wolf" knows best, it's scare fare.

Season 2 of "Teen Wolf" won't air until 2012, but in the meantime, you can check out your favorite cast members from the show in "Charlie Brown: Blockhead's Revenge," the Funny Or Die Halloween exclusive that stars Colton Haynes, Dylan O'Brien, Tyler Hoechlin, and Holland Roden.

The mock horror film trailer features O'Brien as Charlie Brown... when Charlie Brown has had about enough of being Charlie Brown. We particularly love Hoechlin's Schroeder wig and Haynes' ever-present Linus blankie.

Happy Halloween!
