I went to the theater expecting so much from this movie, I just have to say that Downey played an excellent IRON MAN and that he gave an awsome performance, and Bridges got me going the entire movie, Paltrow provided a softer, more feminine side of the film, which of course I enjoyed, I mean c'mon IRON MAN as your man wooooo, but I personally enjoyed Howard's supporting role because he was sensitive for the ladies but in such a high ranking as an officer, obtaining all the manly for the guys. As far as Samuel goes I really don't remember seeing him in the film at all, so I think that sums his role in the movie up. All in all I'd have to say from my point of view this movie was soooo extremely awsome that I was sooo glad to have contributed to the box office.
