There's been a lot of speculation around the fact that because the studio and the director pulled rank on him, he refused to do very much promotion for the film (the only late-night stop he made was Jimmy Kimmel). Norton's camp says he was never supposed to do more publicity than that and this is just much ado about nothing.
It's hard to believe he wasn't asked to do more to promote a major blockbuster leading up to its opening. If he's embarrassed by the film, I can see how it would be hard to discuss with reporters, but then again that's sort of his job as "star of the movie," isn't it? If he wants to have more control of a film, maybe he should just direct.
What do you think? Was he well within his right to skip press after his creative input was denied? Or is he being slightly immature?
