buffy horror moviefest!

I've been wanting to do a Buffy-themed bad horror moviefest for a while now, and I think I've convinced my roommates that with only 99 days til graduation, we gotta do it soon.

So I need to compile a list of all the bad low-grade horror movies that feature Buffy/Angel characters. And I think you guys should help me, cause I can't remember them all. So far we have:

The Grudge
I Know What You Did Last Summer
Psycho Beach Party (which is my favorite ever)
Idle Hands (which I admit I watched solely for the Seth Green factor)
Valentine
Jawbreaker
Wrong Turn
Darkness Falls
They
Scream 2
Pinata: Demon Island
The American Pie trilogy (they're pretty scary when you think about it)
Ravager
Soul Survivors


What else? I know there's got to be a movie featuring Giles or Willow or something. Help me out here, people. Please? :)
