Most memorable horror movie: Grindhouse (2007)

Number of horror movies she starred in: 8

Ever since she starred in 1996's Scream, Rose McGowan has had a tendency to choose roles that were more hair-raising than highbrow. With her seductive, bad-girl looks, the casting is always spot on. And while we'd like to see her spread her wings, so to speak, we're not so sure that'll happen. She did once date Marilyn Manson after all, which proves her penchant for all things creepy.
