'Captain America' Faces New Foes In 'Captain America: The Winter Soldier' [Trailer & Pictures]

In his first solo adventure set in the modern day, Steve Rogers, aka Captain America, is still heavily involved with the agents of S.H.I.E.L.D. and is up against what could be one of his most challenging threats yet. Chris Evans is back as the Captain, and Scarlett Johansson and Samuel L Jackson return as Black Widow and Nick Fury respectively. Plus, there's an appearance from Robert Redford, as S.H.I.E.L.D. boss Alexander Pierce and no shortage of action in our first glimpse at the film.

Chris Evans returns as Steve Roger/Captain America

Following events that took place during World War II and his confrontation with Nazi adversary the Red Skull, Steve Rogers is frozen and awoken 70 years later to find that the world had changed almost beyond recognition. After helping to fight off the invading alien hoard during the Battle of New York (as seen in The Avengers), he is now reluctantly a part of S.H.I.E.L.D., and the all-American hero is beginning to question the ethics of the organisation and the blurred line between what is right and what is wrong.

Nick Fury (Samuel L Jackson) lays down the law

Struggling to find someone to trust, Rogers puts his questions of loyalty behind him when a member of S.H.I.E.L.D. is attacked, and the whole organisation finds itself questioning what exactly is happening. As Rogers fights off a myriad of assassins, the real threat starts to surface in the form of the Winter Soldier, a name that comic fans should be aware of, and one that should get comic fans pretty excited.

Black Widow (Scarlett Johansson) is one of the few people Rogers can trust
