There are already so many characters appearing in Avengers: Age Of Ultron that it’s hard to imagine any more, yet according to Joss Whedon there could very well be more characters that we’ve yet to see.
Following yesterday’s release of the most recent Avengers trailer, Whedon was asked “will we be seeing Marvel characters who aren’t yet in the preview photos? Are we going to be seeing other Marvel characters that we’ve seen in other films or other parts of the universe?” by Lorraine Cink. Joss Whedon responded in his typical fashion:
Now this could simply mean he’s referring to Anthony Mackie, Hayley Atwell, Idris Elba, or Tom Hiddleston‘s characters; all of whom we know will be making an appearance but who have yet to show up in any of the trailers. One name that hasn’t actually been confirmed as appearing is Chadwick Boseman as Black Panther
