The film is Rampage: The Hillside Strangler Murders. Brittany Daniel made her nude debut in this film, when she was nearly 30.
Brittany placed third among our Top Nude Scenes of 2006.
As for the movie itself, I hated it, although I guess I was supposed to, given the subject matter, so it’s fair to say the movie was appropriately visceral. To be less oblique, one critic called it “relentlessly sadistic.” (My review)
