On Tuesday night, Jimmy Kimmel Live had the pleasure of airing the worldwide exclusive debut trailer for Marvel's upcoming superhero film Captain America: Civil War. The new film will function not only as a sequel to the two previous Captain America films—2011's The First Avenger and 2014's The Winter Soldier—but also as a direct result of 2015's Avengers: Age of Ultron.

Shortly into the trailer, we hear a man of authority telling Steve Rogers/Captain America (Chris Evans) that he's "a wanted man" and that police forces are on the move to apprehend him. Oh, and they aren't interested in taking him alive, either.

The tension comes from split public opinion: Is Captain America a hero or a vigilante? Apparently people are displeased with how he's "operated with unlimited power and no supervision."

The trailer's most shocking moment comes when we realize who has been sent to stop Captain America: Iron Man (Robert Downey, Jr.)! The remainder of the trailer is dedicated to the two superheroes verbally and physically sparring for victory, though who comes out on top is obviously kept secret.

In addition to the new trailer and poster, we have the following synopsis, which Marvel posted to their official website back in May: "‘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."

Other returning actors include Scarlett Johansson (Black Widow), Sebastian Stan (Winter Soldier), Anthony Mackie (Falcon), Emily VanCamp (Agent 13), Don Cheadle (War Machine), Jeremy Renner (Hawkeye), Paul Bettany (Vision), Emily Olsen (Scarlet Witch), Paul Rudd (Ant-Man), and Frank Grillo (Crossbones).
