Captain America 3: 10 Questions About RDJ's Involvement

7. Does It Mean There'll Be An Iron Man 4/More Movies With Tony Stark?

Having signed on to appear in Captain America 3, we wonder what else Robert Downey, Jr. has signed on for in the future of the Marvel Cinematic Universe. His interview with Ellen DeGeneres recently seemed to suggest that Iron Man 4 was at least a possibility and the fact that this movie will likely have repercussions that will involve Stark in the future would certainly suggest that he'll need to be around again. So, will there be an Iron Man 4? Will the third Avengers movie still be Robert Downey, Jr.'s swansong in the Marvel Cinematic Universe? We think that we'll probably find out the answer to this question very soon.
