They used to be such good friends. Now, they are bitter enemies. A new international trailer has arrived from Marvel's epic summer blockbuster Captain America: Civil War. And it puts former besties Black Widow (Scarlett Johansson) and Hawkeye (Jeremy Renner) on opposite ends of a big battle that both sides are finding impossible to beat. The rest of this action-packed sneak peek is pretty close to the second trailer that debuted a few weeks ago. But these few seconds of new footage makes it all worthwhile!

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.

Team Iron Man includes Tony Stark (Robert Downey Jr.), Black Widow (Scarlett Johansson), Vision (Paul Bettany), War Machine (Don Cheadle) and the new character T'challa (Chadwick Boseman), who will make his debut in this movie before starring in Black Panther, set for release on February 16, 2018. Team Cap includes Captain America (Chris Evans), The Falcon (Anthony Mackie), Scarlet Witch (Elizabeth Olsen), Hawkeye (Jeremy Renner), Ant-Man (Paul Rudd) and The Winter Soldier (Sebastian Stan). Marvel's Captain America: Civil War also stars Frank Grillo as Crossbones, William Hurt as Thaddeus Ross and Daniel Brühl as the villainous Baron Zemo.
