When we first heard the official title for the sequel to Marvel's Captain America: The First Avenger, we were intrigued to hear it would be the "most closely associated with Avengers."
Since the official (and vague) synopsis says the flick will "pick-up where … The Avengers leaves off," we hear Jeremy Renner and Scarlett Johansson will have major roles as Hawkeye and Black Widow's backstory will reportedly be explored.
They'll be joining Falcon — a role which may go to Anthony Mackie — and the Captain in the fight against the mysterious Winter Soldier.
So who is this guy? (SPOILER ALERT!)
