Captain America: Civil War is a 2016 American superhero film featuring the Marvel Comics character Captain America, produced by Marvel Studios and distributed by Walt Disney Studios Motion Pictures. It is the sequel to 2011’s Captain America: The First Avenger and 2014’s Captain America: The Winter Soldier, and the thirteenth film of the Marvel Cinematic Universe (MCU).
The film is directed by Anthony and Joe Russo, with a screenplay by Christopher Markus & Stephen McFeely, and features an ensemble cast that includes Chris Evans, Robert Downey Jr., Scarlett Johansson, Sebastian Stan, Anthony Mackie, Don Cheadle, Jeremy Renner, Chadwick Boseman,Paul Bettany, Elizabeth Olsen, Paul Rudd, Emily VanCamp, Tom Holland, Frank Grillo, William Hurt, and Daniel Brühl. In Captain America: Civil War, an act regulating superhuman activity fractures the Avengers into opposing factions, one led by Steve Rogers and another by Tony Stark.
Despite all we saw in the Captain America: Civil War trailers, the movie is the moment all Marvel fans have been waiting for. After five movies at the SONY studios, Spider-Man has finally made his debut in the Marvel Cinematic Universe in the Captain America: Civil War trailer 2.
But why does Iron Man call Spider-Man “Underoos” in the Civil War Trailer 2? Well, if you don’t got the joke, Underoos is a brand of underwear. Basically, while every other Marvel hero in the MCU so far has had a pretty practical combat uniform, Spider-Man would not look complete without his classic spandex outfit. As such, he stands out in comparison with the rest of the team, and the velvet spandex look of his costume sort of looks like thermal underwear. Since Tony has a tendency to give snarky nicknames to his teammates, poking fun at the fact that Spider-Man looks like he’s wearing full body underwear is the obvious joke.
TONY STARK: You just started a war.
TONY STARK: Stay down. Final warning.
STEVE ROGERS: I can do this all day.
TONY STARK: All right, I’ve run out of patience. Underoos!
Pick a side! Captain America: Civil War hits theaters on May 6.
