UPDATED 1-31-14 @ 6:37 AM PT: A new, international poster featuring all three main characters, plus Sebastian Stan's Winter Soldier and Robert Redford's head of S.H.I.E.L.D., has been added to the lineup.

As the release date of "Captain America: The Winter Soldier" approaches, the promotional campaign for the Marvel Studios film speeds up: Thursday brings, via Screencrush, both three new character posters -- featuring Chris Evans as Cap, Scarlett Johansson as Black Widow and Samuel L. Jackson as Nick Fury -- plus five behind-the-scenes photos, including the first look at former UFC welterweight champion Georges St-Pierre as Batroc, and a new shot of Anthony Mackie as The Falcon.

These new images serve as prelude to the movie marketing coup de grâce: A "Winter Soldier" Super Bowl commercial slated to unfold this Sunday during the big Seahawks/Broncos game. Directed by Joe and Anthony Russo, "Captain America: The Winter Soldier" opens April 4.
