YES, I mean I think he gets understandably prickly about critics wanting to shove him, RDJ, into the Tony Stark role, but there are also so many similarities and I do think that's at least some of what drew him to the part. And which he does so well. (I DO wish they'd tried to do at least some of the Man in a Bottle story, sigh. I guess IM2 is the closest we're getting.)
