Also making his Avengers debut is James Rhodes (Don Cheadle) - better known as War Machine - who apparently has a "key role" in the battle with Ultron.
No cameo for [The Avengers] big bad Loki, though..."I don't think there's anything else Loki could contribute narratively," admits actor Tom Hiddleston. "I think keeping it fresh and new is good for The Avengers, even though it's a shame for me.
It's also stated Clark Gregg (Agent Coulson) will be missing from the movie as the Avengers still believe Coulson has been killed by Loki. Then it is stated to expect Coulson's story to be played out in The Avengers 3.
