'Batman Begins' came out and it was really successful, and it had gritty naturalism. And suddenly... I can't tell you how many movies I was pitched where it was, 'We want to do what you did with 'Batman' but with 'Teenage Mutant Ninja Turtles,' or whatever.

Superman has evolved continually in the comic books over the course of 75 years. He couldn't even fly for years in the original comic books. Kryptonite wasn't added until the '60s. All sorts of things like this. If a character is going to remain vital, he does have to change with the times.

Sometimes you see films, not just science fiction films, where you get the sense that if the camera were to pan just to the left or the right, all of a sudden you'd be seeing light stands and crew standing around. But with 'Blade Runner,' the beauty of it is that it felt like a real, breathing city.

I was honestly a cartoon kid. I loved cartoons. That was more my dream than anything else. But now, it's the films of people like John Cassavetes and Gena Rowlands. Those are the kinds of characters I want to play, and that's the kind of filmmaking I'm fascinated by.
