I think she actually did that stunt though (Sarah Michelle Gellar). If you watch the commentary, the chick mentions how she was actually scared to do that stunt because of how high they were. Which is weird because I still don't see Sarah Michelle Gellar doing that stunt herself. That would terrify me. But I would have to say that is my favourite death scene in the movie.
Gale: Jesus, the camera! Hurry!
Kenny: My name isn't Jesus.
