There wasn’t really a superhero genre before X-Men came out. Funny enough, I remember catching a plane while we were promoting The Prestige with Chris Nolan [who] said to me that he’d always had the Batman in his mind. Even way back before 2000, he had the version of Batman that he ended up making in his head. He said, ‘when I went into the cinema and saw X-Men, I said damn, that’s my idea.’ The idea that you could really dive in to the emotional life, to the vulnerability of these characters and that, as well as being fantastical, amazing and action, is what’s going to hook people and make them care. That’s what Bryan did, he had a lot of courage to do that.
