During the information bonanza that is Entertainment Weekly's latest issue, Feige spoke of Freeman's role in a very carefully worded statement. Considering all of the other information the publication had gotten out of him, the following clues were just a bit sparse:
He’s under the cloak of secrecy. There are a lot of amazing actors in this movie. Some of them play larger roles than others. And in some cases there are some you will meet ever so briefly in this film and then will be expanded upon in future films. He falls into that latter category.
So here's what we know about Martin Freeman's leap into the MCU so far: he's a "government attache" who will make a small appearance in Captain America: Civil War, and eventually become a bigger part of the Marvel universe at large. As we previously reported, the hottest prospect speculated so far is the role of Everett Ross – an American agent who serves as the ambassador to Wakanda. This would not only pave the way for him to also appear with former Lord Of The Rings co-star Andy Serkis in the upcoming Black Panther film, but it also helps us see where Freeman's role might be going from here.
As Kevin Feige has mentioned the possibility of numerous films, it can be presumed that Ross will be a fixture in the continuing adventures of Black Panther's super-powered Wakandian, with opportunities for supporting appearances in other franchises. So if Joe and Anthony Russo were so inclined, they could borrow Freeman for their two part epic, Avengers: Infinity War, which might also wind up being a mini-reunion for the actor, as Benedict Cumberbatch's Doctor Strange may be present as well.
While we're not being promised a lot of Martin Freeman action in Captain America: Civil War, it looks like there's room for more of his antics in future Marvel films. If that's not job security, then frankly we don't know what is. What we do know though is that Freeman will be a government figure, which means that he'll more than likely be fighting against Cap and friends when they take the fight to the streets in Captain America: Civil War on May 6, 2016. If he's smart, he'll start re-enforcing his office with Vibranium walls, for obvious safety purposes.
