The millions or billions of micro decisions that you're going to make, that's what will determine who you are as a writer, not you deciding in advance.
I think a lot of people don't take you seriously if they hear it's a video-game-based movie, and a lot of press people don't write about you. With BloodRayne, a lot of serious newspaper people didn't actually even see the movie. They went online to see other reviews, and then wrote their own. I think comic-book-based movies have a better image. We see it with 300, Sin City, Spider-Man - they are A-list features, and video-game movies are B-list.
