It has been long rumored, but now it seems like a very popular Marvel story arc will indeed be adapted into the cinematic universe!
Marvel is reportedly finishing up negotiations with Robert Downey Jr. in order to include Iron Man in CAPTAIN AMERICA 3. In doing so, Marvel will ultimately launch the “Civil War” story line in which the Avengers split apart and begin going at each other after the US Government asks superheroes to register.
Making “Civil War” a Captain America entity works well with Marvel’s alleged plan to use the “Infinity Gauntlet” arc as the big shebang in THE AVENGERS 3. This also meshes nicely with the rumor that Marvel is trying to Spider-Man back into their cinematic universe, as Spidey is a major part of the Civil War arc.
