To dig this old thread back up. The movie "Hounddog" has now played at the Sundance festival.
There is scene in which Fanning's character is raped but it the scene plays out only showing Fanning's face and hand during the attack. So as it stands when all is said and done the scene is shocking but not explicit and apparently the movie is not very good.
