He's done a number of these awkward interviews actually, first time I saw one I felt a bit sorry for him but now I think he is a twat.
The thing that gets me is, he doesn't have to be at these conventions or speaking to these press people if he doesn't want to. It's totally his choice (not to mention he is getting paid for that ****) and you have to play the game if you take part in the celeb lifestyle not act like a gigantic whinging prick.
