Captain America: Civil War is the clown car of Marvel movies. Joining Chris Evans and Robert Downey Jr. are Scarlett Johansson, Sebastian Stan, Anthony Mackie, Paul Bettany, Jeremy Renner, Don Cheadle, Elizabeth Olsen, Paul Rudd, Chadwick Boseman, Emily VanCamp, Daniel Brühl, Frank Grillo, William Hurt, Martin Freeman, and -- just revealed in the above trailer -- Tom Holland as Spider-Man. There will likely be more names we don't know about. Stan Lee will definitely cameo. Gwyneth Paltrow will probably cameo. Maybe Christiane Amanpour will reprise her Iron Man 2 role of Christiane Amanpour -- anything is possible!
Captain America: Civil War picks up at the end of Avengers: Age of Ultron, with Mr. America (Evans) and his newly formed team of Avengers in a political pickle. The government wants the heroes to agree to a system of accountability. Captain 'Merica says, in more elegant words, "Hell no." Tony Stark (Downey Jr.) aligns himself with The Man. Donald Trump's stance will hopefully be revealed in the final product.
