Paul Rudd does his first crossover.

Way back in November I told you guys some stuff about Captain America: Civil War, including the fact that in-house they were calling it Avengers 2.5. It's certainly becoming more and more clear that the film is going to be jam-packed with Marvel superheroes, and today's start of shooting announcement added one more to the mix: Ant-Man.

From today's press release: 

After his debut in Marvel’s “Ant-Man” on July 17, 2015, Paul Rudd (“Ant-Man,” ”Anchorman 2: The Legend Continues”) will make his first appearance alongside the Avengers as Scott Lang/Ant-Man in “Captain America: Civil War.”

That sort of makes it sound like joins The Avengers, but I'm not quite sure. 

The press release includes a new synopsis of the movie as well: 

“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.

That villain is the classic Captain America villain Baron Zemo, played by Daniel Brühl. He's joining a huge cast that looks like this: 


Captain America - Chris Evans

Iron Man - Robert Downey Jr

The Falcon - Anthony Mackie

Black Widow - Scarlett Johansson

War Machine - Don Cheadle

Hawkeye- Jeremy Renner

Scarlet Witch - Elizabeth Olsen

The Vision - Paul Bettany

The Winter Soldier - Sebastien Stan

Agent 13 - Emily VanCamp

Black Panther - Chadwick Boseman

General Thaddeus "Thunderbolt" Ross - William Hurt

Crossbones - Frank Grillo

Everett K Ross? - Martin Freeman

Holy crap that's a huge cast. And it gets me excited. I wonder how much screentime some of these characters will have; I kind of suspect that a lot of The Avengers turn against Cap, leaving him with his basic Winter Soldier team of Falcon and Widow. How will Ant-Man play into it? It could very easily be a cameo by Rudd; I don't know that Ant-Man ends in a place where he's ready to actually join the team, no matter what the press release says. Perhaps Cap and friends have to turn to Ant-Man for some heist business - that would be amazingly cool.
