Regarding his appearance in Captain America 3, Renner addressed the rumour but did not exactly rule out the possibility (via Moviepilot):

"Oh, that's a rumour all right! I don't know what's going to happen. I know it's going to start shooting in March. I haven't had any official conversations about doing it or not."

The actor went on to discuss Avengers 2 revealing that 'most actors' will be returning for the superhero film franchise's third installment:

"I think most actors will sign on to do, like... Captain America 1-3 and then The Avengers 1-3, and then you're done. For me, I signed on to The Avengers 1-3 and then Hawk-Eye, in case they want to do a Hawkeye spin-off. It was fun to finally kind of discover who Clint Barton is a little bit," he said.

The American Hustle actor revealed details about the Avengers' role in the upcoming sequel:

"Hulk has a more prominent role, and I have a more prominent role. There are a lot more scenes of the entire Avengers gang together—both in and out of the cape, so to speak. It's making me become a total fanboy. It's pretty fun to be a part of.

"We have some good secrets revealed. I think everything that was great about the first Avengers, is exponentially expressed in this one. From the action, to the making fun of itself, and there's a lot more time spent with the Avengers together, after being so separated in the first one. We've got some great new goodies, and some good baddies," he said.

Addressing the Avengers teaming with the Guardians of the Galaxy rumour, Renner said:

"That would be awesome. I think that would be awesome. Of course that's the hopes with the puppeteers behind Marvel, but we'll see, man. We'll see..."
