According to a report by Comicbook.com, Sam Rockwell, who played the villain Justin Hammer in Iron Man 2, said that he hopes he has another shot at playing Tony Stark's nemesis. In an interview with the Hollywood Reporter, Rockwell said, "I have some great buddies in that franchise. Jeremy Renner is a good friend of mine, and I am pals with Chris Evans and Mark Ruffalo. Robert [Downey Jr.] is always fun. Would love to get me and Clark [Gregg] back in that franchise. That would be a lot of fun." Comicbook.com points out that in at least one fan theory, the MCU may be building up to a story arc that may have a place for Justin Hammer to make his return.
