Joss Whedon, writer/director for Avengers 2 has revealed that the Avengers 2 Age of Ultron will continue the storyline from Captain America 2: The Winter Soldier.
He explained at the recent Comic-Con that Captain Rogers will continue that search in Avengers 2, but however it all changes when the Ultron decides to point their guns on earth that made the Captain to gear up again for the Avengers.
The fact is, Ultron is a clear and present danger and Bucky’s in the wind. We do mention the fact that that this is sort of a primary thing, but he’s also working with The Avengers too,” Whedon said, according to Cinema Online.
“We’re not ignoring it, but he definitely has to deal with a mad eight foot robot, because that’s one of those things that you put it off and it just gets worse.”
