Almost exactly one year from now -- on May 6, 2016 -- a bunch of people you just saw in "The Avengers: Age of Ultron" will return in "Captain America: Civil War," along with a few familiar faces from other places, and some total newbies who remain mysterious. For now.

Emily VanCamp, very soon to be a "Revenge" alumnus, is returning to "Captain America" as Agent 13, aka Kate/Sharon Carter. She was briefly in "Winter Soldier" as next door neighbor Kate, assigned to protect the hero. Not sure what she'll be up to in "Civil War," but Emily tweeted confirmation about the scoop:

But not too long after that news came out, Marvel Studios announced that the Avengers would return in full for "Civil War." In a media release, Marvel noted that principal photography had begun in Atlanta, Georgia, but other locations for the third "Captain America" movie will include Germany, Puerto Rico and Iceland. Chris Evans will be joined by Robert Downey Jr.'s Iron Man, Scarlett Johansson's Black Widow, Anthony Mackie's Falcon, Paul Bettany's Vision, Don Cheadle's War Machine, Elizabeth Olsen's Scarlet Witch, Jeremy Renner's Hawkeye, and Sebastian Stan's Winter Soldier.

Plus, after his debut in "Ant-Man" on July 17, 2015, Paul Rudd will make his first appearance alongside the Avengers in "Civil War."

Marvel also listed the "additional cast," including VanCamp, but also Chadwick Boseman ("42," "Get on Up") as T'Challa/Black Panther, Daniel Brühl ("Inglourious Basterds," "Bourne Ultimatum"), Frank Grillo ("Captain America: The Winter Soldier," "Warrior") as Brock Rumlow/Crossbones, William Hurt ("A History of Violence," Marvel's "The Incredible Hulk") as General Thaddeus "Thunderbolt" Ross, and Martin Freeman ("The Hobbit: An Unexpected Journey," "The Hobbit: The Battle of the Five Armies"). Note, they didn't say a single thing about Freeman's character. Those teases!

But we're not done yet. Here are some early plot details from Marvel:

"Captain America: Civil War" picks up where "Avengers: Age of Ultron" left off, as Steve Rogers leads the new team of Avengers in their continued efforts to safeguard humanity. After another international incident involving the Avengers results in collateral damage, political pressure mounts to install a system of accountability and a governing body to determine when to enlist the services of the team. The new status quo fractures the Avengers while they try to protect the world from a new and nefarious villain."

Is Martin Freeman the new and nefarious villain? Guess we'll have to stay tuned for more details. What do you think of the cast and story intel so far?
