Robert Downey Jr. May Not Do ‘Iron Man 4,’ But He Is Doing ‘Captain America 3’

Robert Downey Jr. has said (over and over) that there are no plans for Iron Man 4, and Marvel big wig Axel Alonso has hinted that there may be a new Iron Man. But nobody ever said Robert Downy Jr. was done playing Tony Stark, and nobody ever said he wouldn't appear in other Marvel movies. So the fact that RDJ is set to joint the cast of Captain America 3 should not come as a complete shock. In fact, when you think about it, it all makes perfect sense.

According to Variety, Marvel is bringing their "Civil War" storyline to the big screen for Captain America 3 and (one would have to assume) Avengers 3. I don't want to spoil it for you, but I think you can tell from the very title that there's a falling out. And since Steve Rodgers and Tony Stark didn't get along too well in The Avengers, I don't think it is giving too much away to say the falling out is between Captain America and Iron Man.

Given that we already knowChris Evans doesn't intend to be Captain America ad infinitum, and that Marvel has hinted that Tony Stark may be less of a good guy going forward , Captain America 3 looks like it's going to be a pretty big turning point in the Marvel Cinematic Universe.

Hold on to your hats.
