Rape scene in Irreversible was so fucked up, had to take a break and go outside after that.
I have no problem with rape scenes in general if they serve the purpose of telling a story. Irreversible was two scenes based around how fucked up those two scenes were. Everything between was improvised nonsense. Lars Von Trier and Gaspar should make a film where they fuck each other up the ass. They can switch off directorial doodies.
