During the conference, brothers Joe and Anthony Russo -- who directed the film -- explained that the films would be "very different" from the prequel as the Captain "is not in the modern world and the film is a political thriller."
"You can't have thrills in the thriller unless the characters are in a real state of jeopardy. So Captain goes through a lot in this film. It's action-heavy and a very intense movie," Joe explained.
Though no real details about the plot were revealed during the conference, the directors did introduce a few new characters including Black Widow played by Scarlett Johansson, the Winter Solider played by Sebastian Stan, Falcon played by Anthony Mackie, a mysterious S.H.I.E.L.D. agent played by Robert Redford and Agent 13, played by Emily VanCamp.
"I can't reveal too much about the character," VanCamp said. "I think people have a certain idea of what I'm meant to be playing, but I think you'll be surprised at how we use this character. Compared to other characters I've done, it was certainly a challenging experience and an exciting experience."
Chris Evans, who plays Captain America, explained that one of the sequel's biggest differences from the first movie lays in the way he interacts with modern society.
"The hurdle of Captain America is that his nature is to put himself last," Evans said. "The first Captain America film is about getting the opportunity to serve, the opportunity to lead, to be a soldier. I think he's so determined to do what's right. The conflict with this modern society as opposed to the '40s is in the '40s, it was easy to say 'the Nazis are the bad guys.' Today it's a little bit harder to know 'who am I serving?'"
