Despite a cast that is pretty well jam-packed, Captain America: Civil War is not quite done. The upcoming Marvel sequel — jokingly codenamed Avengers 2.5 — has now added Emmy-winning actor and The Hobbit star Martin Freeman to the cast in an unspecified and secret role.

In typical Marvel fashion, they announced the news but revealed nothing else about it. Said Kevin Feige in a statement:

Martin's range from the dramatic to the comedic has consistently impressed us. We couldn't be more honored or excited to have such a talented actor join the Marvel Cinematic Universe.

And that's about all we know.

Most of the major roles in the film have been cast, so don’t expect Freeman to be playing some major Marvel superhero. As we speculated here in the office, he’s likely playing some kind of government official involved with the Civil War program, or as Matt Singer put it, “Senator Tom Dweebsman”.

Freeman joins a cast that includes (*takes deep breath*) Chris Evans, Robert Downey, Jr., Chadwick Boseman, Sebastian Stan, Frank Grillo, Elizabeth Olsen, Scarlett Johansson, Jeremy Renner, Anthony Mackie and Daniel Bruhl (*whew*). The film itself goes a little something like this:

Following the events of Age of Ultron, the collective governments of the world pass an act designed to regulate all superhuman activity. This polarizes opinion amongst the Avengers, causing two factions to side with Iron Man or Captain America, which causes an epic battle between former allies.

Captain America: Civil War, which is currently filming, is set to open in theaters on May 6, 2016.
