The second installment will pick-up where The Avengers off, as Steve Rogers continues his affiliation with Nick Fury/S.H.I.E.L.D and struggles to embrace his role in the modern world.
As it turns out, Captain America 2 and the SHIELD movie are one and the same, and that tidbit above is our first clue. It confirms Samuel L. Jackson will return, and if his organization is heavily involved – which it is since Steve Rogers works for them – then we can expect others, like Maria Hill to factor in as well.
Plot points for the up and coming sequel (Potential SPOILER Warning):
According to The Playlist, Black Widow and Hawkeye may also be involved in Cap. 2 and there will be some romance between them. The pair of agents shared plenty of screen time in The Avengers, and having them fight together again works within the context of a modern-set Captain America story. In an attempt to bridge continuity with the rest of the “Phase 1″ Marvel Studios films, General “Thunderbolt” Ross (William Hurt) from The Incredible Hulk may make an appearance, along with several key characters from the first Captain America.
AWW YISS GENERAL ROSS.
I just really like William Hurt, okay?
