Katherine Waterston in Inherent Vice. Very nice dense beaver. Not sure if merkin. I just wish her scene was longer.I think there is some rule in Hollywood stating that women have to have a nasty bush in order to show their nude crotch in a movie. I don't think I have ever seen a shaved pussy in a Hollywood movie.
Edit: Rosario Dawson flashed her shaved pussy in the movie Trance.
Eva Green in The Dreamers. Slow moving camera from toes to head. Her co-star got to have some hair on his face/mouth.
