Sex and horror movies have had a mutually beneficial relationship for decades. Something about the arousing power of fear strikes right at the heart of human nature, and filmmakers have long been eager to exploit that. We don't mind at all.

For some reason, we found a lot of sexiness in the various Texas Chainsaw Massacre remakes and sequels -- just look at some of the women who've had leading roles in this franchise, starting with:
