Captain America star Chris Evans has confirmed that there will be cameos from some of his fellow Avengers in Captain America: The Winter Soldier. Chris also stated that he has yet to receive a copy of the script for the movie, which is set to begin shooting in June.
Evans told the Doug Loves Movies Podcast, “I don’t have a script yet. We start shooting in two months and they haven’t given me a script. That’s how Marvel works. Different directors, it’s the Russo brothers. It makes perfect sense, Community, S.H.I.E.L.D. superhero action movie.”
He then went on to admit that there would definitely be some cameo appearances from some of the other Avengers, although he could not reveal who, “Yeah, they’ll be some. That’s going to get me in trouble (with Marvel),” Chris added. [Source]
