Welcome to a film that you may watch once, but will never want to revisit, if only for your own sanity. Told with sickening brutality by Argentinian film maker Gaspar Noe, it depicts the rape of a young woman on the way back from a party, followed by the consequence driven quest for revenge by her lover - in reverse. As you are still trying to understand (and mentally block out) Vincent Cassel smashing a man's face to a pulp with a fire extinguisher (think the 'Drive' elevator scene, but with no cuts), you are presented midway through with the reason - the brutal rape of his girlfriend in a subway. It is a six minute static shot of Monica Belluci being raped for what feels like a lifetime, then she is battered and left for dead. Bellucci herself has said "When I see the rape scene on screen, I can't handle it. I turn my eyes away." Her frighteningly raw reaction to the most heinous act that can become a human being is uncomfortable and one that you will never wish to see again, this is despite how confronting her performance may be.
