Captain America appears to be thinking small when getting recruits for the forthcoming “Captain America: Civil War.” A new sneak-peek clip shows Ant-Man happily joining Captain America’s side in the hero vs. hero battle between Avengers.

The new video clip of “Captain America: Civil War” premiered on “Jimmy Kimmel Live” Monday night and showed Captain America (Chris Evans) beginning to assemble his team. Hawkeye (Jeremy Renner) opens up the doors of a white van to reveal Scott Lang, aka Ant-Man (Paul Rudd). Lang is napping at first, but when the doors open he wakes up and is surprised to see Captain America, Falcon (Anthony Mackie) and Scarlet Witch (Elizabeth Olsen). The Winter Soldier (Sebastian Stan) also appears in the background.

Lang walks over to Captain America after looking starstruck, and he shakes his hand for a bit too long. “Wow, this is awesome. Captain America!” Lang says. He then turns to Scarlet Witch and says, “I know you, too: You’re great.”

After 2015’s “Ant-Man,” it’s no surprise Lang will be joining Captain America’s squad in “Captain America: Civil War.” In his namesake film, Ant-Man had a brief fight with Falcon where he was able to get the upper hand on the hero. Ant-Man defeated the Avenger and was able to escape with a Stark device that would help him with his heist of the Yellowjacket suit.

Despite the addition of Ant-Man, Captain America’s squad is going to have their hands full in the new movie. Iron Man (Robert Downey Jr.) has a handful of recruits of his own he’ll be taking into battle with him. Black Widow (Scarlett Johansson), War Machine (Don Cheadle), Vision (Paul Bettany) and Black Panther (Chadwick Boseman) will all be by his side. He’ll also get some help from the new Spider-Man (Tom Holland), who made his debut in the latest “Captain America: Civil War” trailer.

Captain America and Iron Man disagree in the new film about how the Avengers should be used, which leads to their so-called civil war. Many people want a system of accountability installed to overlook the Avengers as a way to keep them in check, but Captain America believes the Avengers should be able to act with no government involvement. After the events of the first two “Avengers” movies, Iron Man believes the team needs an entity to direct them.

“Captain America: Civil War” hits theaters May 6.
