I think that he should do another movie or two, and then stop and or move on from the role. I know that he's probably going to make a craptop (For lack of a better word. Hey, I think that I just invented a word. Cool!) of money, and people will probably always see him in the role (Like Jack Nicholson or Heath Ledger.), but I do think that there is a danger of overexposure or getting typecast. And Downey has done good work in the past (Tropic Thunder, Kiss Kiss Bang Bang, and he was supposed to be very good in Chaplin.), so he won't be a one-hit wonder or anything (Like, say, George Reeves.). Hugh Jackman was in 9 (Or 10.) X films, and now he's officially finished. I'm kind of surprised that they haven't made a fourth Iron Man film, but I don't think that they should since they have the Avengers franchise. With this upcoming Avengers film, Downey has 7 in the can. What do you guys think?
