Last night during the Super Bowl, viewers got a first look at the second official trailer from Captain America: The Winter Soldier. While the first trailer dealt with Cap's unease in his role as a full-fledged agent of S.H.I.E.L.D., the new clip puts the focus on the titular villain, the Winter Soldier. A metal-armed assassin who's able to capture Captain America's shield, the mystery villain is clearly able to take on both Captain America (Chris Evans) and his new partner the Falcon (Anthony Mackie). No spoilers here, but the Winter Soldier's identity will be familiar to readers of the recent Captain America comic book storyline. Speaking of familiar characters, look for the return of Scarlett Johansson's Black Widow and Samuel L. Jackson's Nick Fury. Veteran actor Robert Redford joins the cast as Alexander Pierce, a S.H.I.E.L.D. bigwig. Check out the trailer below, and expect Captain America: The Winter Soldier to hit theaters April 4th.
