The Avengers: Age of Ultron has yet to hit theaters, but rumors regarding Avengers 3 are already flying.

'Avengers 2: Age Of Ultron' To Set Up Drax For 'Avengers 3'? Will The Guardians Of The Galaxy Come To Earth?

Agents of SHIELD loaned out at least one agent to the Age of Ultron cast (Agent Triplett as played by BJ Britt), and the ABC/Marvel series may choose to move Mockingbird (Adrianne Palicki) in the big screen as well.

Set to premiere on Agents of SHIELD as the head of HYDRA security, Palicki told IGN that teaming up with Earth's Mightiest Heroes was discussed as well.

"Absolutely - that was one of the things that was discussed when I was coming on for the part, and you know, we'll see what happens," Palicki said. "It's such a nice world that we live in that crossover can happen so often now which in the past it never really did so, to see these worlds come together on the small screen and the big screen is really cool."
