While he has denied making a 4th Iron Man film, Robert Downey Jr. was revealed to appear in the 3rd Captain America film. And, as we said before, this will be the Civil War adaptation, in which Iron Man and Captain America will trade blows over the Superhuman Registration Act!
But then again maybe this won’t happen in Captain America 3, since the movie is set to put in motion several other films – in a way, it will be the beginning of the Civil War. Which is an even better news, since this comic book source needed much more than 2 hours to be translated for the silver screen.
It appears that, as said before, Captain America will have his own team by the end of Avengers: Age of Ultron. This will most likely have huge ramifications, possibly bringing a whole new team in Avengers 4.
Check out the story line for Captain America 3:
“The plot will pit Stark against Captain America’s alter-ego Steve Rogers, played by Chris Evans, as they feud over the Superhero Registration Act, which forces anyone with superhuman abilities to reveal their identities to the U.S. government and agree to act as a police force for the authorities. Stark supports the program, but Rogers does not, saying it threatens civil liberties, causing sides to be taken and Rogers, among others, to go on the run to avoid arrest. The moral question and battle with his Avengers teammate essentially makes Stark a villain of sorts in “Captain America 3,” providing Downey with a meaty role he could play out into future Marvel films, including a fourth “Avengers.”
Again, it was pretty obvious that the Winter Soldier will make Steve Rogers question the right of any kind of organization to intervene in the life of the people (Civil… rights).
Even more, now the possibility of Spider-Man joining the Avengers doesn't seem as far-fetched.
PS: RDJ will make $40 million + for Captain America 3…
