Paul Bettany: “As an actor, I have questions. I want to know what I’m doing. And he simply wouldn’t talk to me. You’re not allowed to talk about the film and there is no rehearsal. … He just stands there and says [mimics Danish accent]: ‘Louder! Louder! Do it louder!’ That’s the extent of your collaboration. You know what it’s like? It’s like he’s Jackson Pollock and you’re on the sidelines, mixing his colours.”
