With all the talk about superhero brothers- and sisters-in-arms squaring off over ideological differences in Captain America: Civil War, folks might forget that the film is also the continuing story of James Buchanan “Bucky” Barnes, Captain America’s friend and World War II ally-turned-Winter Soldier. On last night’s episode of Jimmy Kimmel Live!, Robert Downey, Jr. and members of Team Iron Man brought a clip from the superhero showdown featuring Iron Man, Black Widow, and Agent 13 attempting to neutralize Bucky, who’s on the run from the government for his actions as the Winter Soldier.

Downey, Jr. was joined by Paul Bettany (The Vision), Don Cheadle (War Machine), and Emily Van Camp (Agent 13) to discuss the film, as well as discuss where Agent 13’s loyalties lie and how going to the bathroom in makeup as The Vision was problematic for Paul.

Captain America: Civil War, starring Chris Evans, Emily Van Camp, Paul Bettany, Robert Downey, Jr., Don Cheadle, and scores more, hits theaters May 6th.

From the film’s official description:

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. Get ready to pick a side and join the nonstop action playing out on two fronts when Marvel’s “Captain America: Civil War” opens in U.S. theaters on May 6, 2016.
