Along with the opening of Iron Man 3, Marvel is treating fans to some awesome Captain America 2 set photos.  Although Captain America has only been in production for a few weeks, it looks as though Black Widow and Falcon will be playing a major role.  

I'm excited to see Anthony Mackie as Falcon, even if he won't be doning the tight red pants or red wings... It seems that like Hawkeye, Marvel is planning on making a more modern military look for Falcon.  Check out some photos from the set:

Black Widow was also spotted on set along with Captain America himself.  Perhaps the two will become close friends throughout the film?  At this point Captain America has yet to adjust to modern life in America.  The two Avengers seem to be in an altercation with a S.H.I.E.L.D. agent in the set photos below. 

We've yet to see any photos of the Winter Soldier himself, so check back for more updates.  Captain America 2: The Winter Soldier opens April 4, 2014.
