Earlier today, we showed you a new clip from Captain America: Civil War that debuted on ABC's Jimmy Kimmel Live!, featuring Ant-Man's (Paul Rudd) introduction to Captain America (Chris Evans) and his team. Fans also got to see another clip from this superhero adventure during the MTV Movie Awards, which showed Team Cap in action. Now Marvel has unveiled yet a third clip, which reveals how this conflict between Cap and Iron Man (Robert Downey Jr.) begins. If that wasn't enough, we also have nine minutes of behind-the-scenes footage from Captain America: Civil War to check out as well.

The scene features Cap arguing that the document the United Nations wants all of the Avengers to sign is dangerous, because the U.N. has their own agendas at play. Naturally, Tony Stark and Rhodey (Don Cheadle) don't agree, with Tony stating that he shut his weapons down after learning what could be done with them in the wrong hands. This scene also features Black Widow (Scarlett Johansson), Vision (Paul Bettany), Scarlet Witch (Elizabeth Olsen) and The Falcon (Anthony Mackie), which shows how these heroes slowly become divided against each other.

Marvel's Captain America: Civil War finds Steve Rogers leading the newly formed team of Avengers in their continued efforts to safeguard humanity. But after another incident involving the Avengers results in collateral damage, political pressure mounts to install a system of accountability, headed by a governing body to oversee and direct the team. The new status quo fractures the Avengers, resulting in two camps, one led by Steve Rogers and his desire for the Avengers to remain free to defend humanity without government interference, and the other following Tony Stark's surprising decision to support government oversight and accountability.
