Attendees of The Venice Film Festival were allegedly shocked by the content of the opening film, Black Swan, which features scenes of lesbian sex, drug taking, and self-harming.

The Guardian reported that the sex scene between stars Natalie Portman and Mila Kunis elicited quite a response from the festival, which began earlier this week. The movie, directed by Darren Aronofsky, is about the highly-competitive world of ballet.
