The big question following The Avengers: Age Of Ultron is where did Banner and the Hulk go off to?
But perhaps the bigger question is will the Hulk appear in Captain America: Civil War?
As of right now, the Hulk is the only Avenger that has yet to make a confirmed appearance in another Marvel movie.
No Hulk solo movie is being planned as there is a rights issue over the character having standalone movies with Universal Studios.
Now we hear from Mark Ruffalo who offers hope that the Hulk might be featured in Captain America: Civil War.
While Ruffalo spoke to the Daily Beast stating he still doesn't know if the Hulk will make an appearance:
“I don’t know! I heard a rumor about that the other day. I haven’t seen a script, nobody’s told me, and I don’t have dates. But I can only hope so!”
Ruffalo does go on to say that Robert Downey Jr. teased the following:
“I was talking to Robert Downey the other day, and he said, ‘Ruffalo! I heard you’re coming out here,’ and I said, ‘OK! I’ll be there,’” said Ruffalo, with a chuckle.
If indeed Ruffalo hasn't read a script, it doesn't necessarlily mean the Hulk won't show up in Captain America: Civil War as the appearance could be small (such as at the end of the film), and it's possible that Ruffalo might not be appearing as Banner, but the Hulk would be CGI.
Another rumor/fan-speculation going around the net is that the Hulk will appear - as the Red Hulk. Fans of the Marvel comics know that General Thunderbolt Ross is the Red Hulk; William Hurt returns to reprise Ross for Captain America: Civil War.
Another intersting tidbit is the following tweet Ruffalo posted last month:
"Captain America: Civil War" has a May 6, 2016 release date directed by Anthony and Joe Russo starring Chris Evans, Robert Downey Jr., Scarlett Johansson, Jeremy Renner, Elizabeth Olsen, Sebastian Stan, Anthony Mackie, Frank Grillo, Paul Bettany, Don Cheadle, Emily VanCamp, William Hurt, Martin Freeman and Chadwick Boseman as Black Panther.
Captain America: Civil War picks up where Avengers: Age of Ultron left off, as Steve Rogers leads the new team of Avengers in their continued efforts to safeguard humanity. After another international incident involving the Avengers results in collateral damage, political pressure mounts to install a system of accountability and a governing body to determine when to enlist the services of the team. The new status quo fractures the Avengers while they try to protect the world from a new and nefarious villain.
