Personally I don't think there's any real intrinsic difference between comic books, movies, theatre, novels. I know there's sure to be some differences of some sorts. I've worked on novels, films, and video games, and in an adaptation, I guess one of the issues is that I have to be in love with the thing I'm adapting before I do it. So that can cause a problem. You can be too scared of it. You could be too reverential. But at the same time you want to try to capture this thing that you're obsessed by. You're fixated for a reason. What's the reason? You try to get ahold of it.
