We already got a new dose of Captain America: The Winter Soldier footage with the trailer and Super Bowl commercial that debuted yesterday. However, there is one character that we haven't seen yet, Sharon Carter, played by Revenge star Emily VanCamp. Thankfully, Marvel UK has debuted an international trailer that gives us our first look at this Sharon, also known as Agent 13, who is the niece of Peggy Carter, played by Hayley Atwell in 2011's Captain America: The First Avenger. We also get scenes with Captain America (Chris Evans) doing battle against The Winter Soldier (Sebastian Stan), along with The Black Widow (Scarlett Johansson), Nick Fury (Samuel L. Jackson), The Falcon (Anthony Mackie) and Crossbones (Frank Grillo) in this Marvel Phase Two sequel, arriving in theaters April 4.
