The wait is over. Marvel has just released a first teaser trailer for the up coming Captain America: Civil War. Featuring an array of avengers from the Marvel U, including Captain America, Iron Man, Hawkeye, Falcon, Black Widow and more (Not seen, Ant-Man, Vision and Spider-Man) Civil War is based on the hit 2006 comic book which pitted hero against hero on the subject of hero registration.
The movie seems to deviate from that story line as the trailer seems to indicate that the primary plot will revolve around the capture of Bucky Barnes AKA The Winter Soldier. Check out the trailer here.
