Captain America: The Winter Soldier Concept Art Shows Fierce Battle

Marvel has released some brand new concept art for Captain America: The Winter Soldier (via EW). The concept art shows Captain America locked in a heated struggle with friend turned enemy: The Winter Soldier (a.k.a. Bucky Barnes).In the background, The Falcon can be seen taking part in an aerial battle going on behind them. There also are some troops on the ground, so there appears to be an all-out war going on.While Bucky Barnes appeared to plunge to his death in the first Captain America movie, it’s a well-known story in the comic book series that he was brought back as bio-engineered super-soldier, who was brainwashed into being an assassin.Captain America: The Winter Soldier is part of Marvel Studios presentation for San Diego Comic-Con, so we’re expecting the first official footage from the film will be released next weekend.Captain America: The Winter Soldier is scheduled to be released in movie theaters on April 4, 2014.
