As Jeremy Renner continues to make the press rounds for his upcoming thriller Kill the Messenger, the actor cleared the air about a certain Captain America 3 rumor and teased new details about Avengers: Age of Ultron. And, despite claiming that he wasn't really interested in a Hawkeye solo movie last week, Renner does confirmed that he is signed on for one should Marvel deem it necessary. He then teases a possible Hawkeye/Black Widow team-up movie.

Most actors who take on a major role in any Marvel movie sign multi-picture deals that will span several years. When asked about his own Marvel contract, Jeremy Renner says the deal includes Marvel's The Avengers, next year's Avengers: Age of Ultron and The Avengers 3, along with a possible Hawkeye spin-off movie:

"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 Hawkeye, in case they want to do a Hawkeye spin-off."

The Daily Beast comments on how great it was that Captain America: The Winter Soldier gave equal time to both Steve Rogers and Black Widow. To that, Jeremy Renner says something quite interesting:

"Right. I think that's why they want a Hawk-Eye/Widow movie so bad."

Now, it's unclear who wants this team up 'so bad'. The Black Widow solo adventure has been rumored for quite some time, but is he hinting that Marvel wants both characters to team-up for their own spin-off? Or is he saying that fans want a crossover with both characters in the lead? It would be killing two birds with one stone. This is quite possible, and sounds logical, but we haven't heard anything official from Marvel. And he may simply be referring to spin-off movies for both characters in the same breath.

Hawkeye and Scarlett Johansson's Black Widow are currently the only two Avengers characters who don't have their own stand-alone movies at this time, but it sounds like that may change in the future.

Last month, Jeremy Renner hinted that "there are rumblings" his character Hawkeye may appear in Captain America 3. In his interview with The Daily Beast, Jeremy Renner clarifies that he hasn't had any official talks with Marvel about joining the cast, but he did know that shooting begins in March.

"Oh, that's a rumor 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."

Production recently wrapped on Avengers: Age of Ultron, but Jeremy Renner revealed that there are still some pick-up shots left to film, while teasing both Hawkeye and Hulk (Mark Ruffalo) have bigger roles in the sequel.

"We have to do some pick-up shots here and there, but for the most part. 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."

In a separate interview with StarPulse, Jeremy Renner said it was nice to learn more about his character Hawkeye, a.k.a. Clint Barton, while teasing that some big secrets will be revealed.

"Well there's a lot more in this next Avengers, which is great. It was fun to finally kind of discover who Clint Barton is a little bit. 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."

After the success of Marvel's Guardians of the Galaxy this summer, many fans have been hoping that the Guardians and Avengers may cross paths in the Marvel Cinematic Universe at some point in the future. Jeremy Renner, who said Guardians of the Galaxy was "tremendous," was asked if he would like to see these superhero teams meet up at some point. Here's what he had to say.

"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..."
