Well, for sheer "shock" for a main-stream film, I would have to say the two scenes in A History of Violence (also an amazing movie - go and see it asap). I won't go into any details because I won't do it justice, but you have my two cents.
wild things threesome scene LOL on a more serious note....i liked betty davis and her love interest in All About Eve for the way they capture what it takes to make love happen. Seeing it for what it is and still desiring it
ummm... I liked the one in Underworld Evolution. And for some reason I am drawing a blank on all of the rest. What the hell. Ahh yes, the one in the Notebook. That one was goooooood. Other than those I guess I don't really have any that really stick out in my mind. I'm gonna have to go through my movie collection when I get home and see if I remember any good ones.
dont watch history of violence with your parents is all i can say. I wished the ground would suck me up.
Sex scenes in Dreamers by Bertolucci are pretty amazing... Both beautiful and very brave. In 60's Paris milieu, what could be more sexual!
A Clockword Orange or 9 Days (I think that's the name of the movie... it's the one with sex, concert, sex, concert).
i was gonna suggest bound as well, but then remembered that scene on the stairs from history of violence that was such a great movie
What they don't show is always intriguing. I liked Secretary with Maggie Gyllenhall(?). +1 on History Of Violence, good film too. Much prefered those sex scenes to the one in Brokeback Mtn.
Ok, that takes the trophy. You don't know love until you've seen naked marrionettes fuck then shit on each other's faces.
