Jon Favreau talks about Iron Man and Marvel Comics in general:
There is a certain amount of responsibility I feel because it’s the first movie Marvel has done autonomously as a studio and I want to make sure the fans know that we’re going to consider them and the history of the source material with a little bit more responsibility than it had been in the past. The studios really, I think, were happy to have the property, but didn’t really feel compelled to stick to it any more than they felt was in their best interest.
