What I really like to do is write 'genre' stories without a cartoonish element. I did the same with 'Da Vinci's Demons,' and I'll do the same with 'Man of Steel.'
'Call Of Duty' initially cut its teeth on World War II simulation stuff, and then we gradually advanced to the end of the Cold War, but you can't keep doing the same thing over and over again. And I think that because 'Call Of Duty' cut its teeth on presenting 'realism,' in quotes... verisimilitude.
I think there's really only been one successful video game adaptation, and that was probably 'Tomb Raider.' Whether or not you thought it was a good movie, it was successful financially.
What Christopher Nolan and I have done with 'Superman' is try to bring the same naturalistic approach that we adopted for the 'Batman' trilogy. We always had a naturalistic approach; we want our stories to be rooted in reality, like they could happen in the same world we live in.
'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.
People have a very proprietary relationship with Superman. It's important to respect the iconography and the canon, but at the same time, you have to tell a story. Once you land on who you think the character is and what his conflicts are, you have to let that lead you.
