I could never make American movies - they like happy endings. I made “Shame” in America, but it’s not a Hollywood movie. I’m about challenging people. Like, properly challenging them and their assumptions. Audiences make their minds up about people they see on screen, just like they do in real life. That’s what fascinates me in film. You see a character and have to think: is this person different to what I assumed he was when I first saw him? … I’m certainly not who people think I am. I always do whatever I want to do and my films are personal to me. “Hunger” was about my youth, the loss of innocence when I realized what my country was doing, what was going on. Brandon in “Shame” is my response to being lost - I’ve not been there in the sense of sexual addiction, but I’ve been lost.
