This past weekend, "Captain America: The Winter Soldier" opened in theaters around the country and by $10 million, beat the previous best opening for the month of April.  The movie has already gone on to earn more than $300 million worldwide as well.  And, the reviews have been good as well.

Prior to the film's release, HitFix's Gregory Ellwood sat down with members of the cast, including Sebastian Stan, who plays Bucky Barnes/Winter Soldier.  As Ellwood notes in the interview, the fight scenes are amazing and assuredly that is no small reason for the film's success. 

Fight sequences can be intense for actors to film, and in terms of the action Stan says that "Everything we could do, we did," and that he and Chris Evans had fight choreography training for about three months. 

During the filming, Stan also had to be able to use a prosthetic arm and had the choice of two – one which allowed more movement, and one which was heavier but looked better.  More often than not, he went with the one that looked better, explaining that being more aware of the aware the prosthetic helped him with the character.

With a Marvel Cinematic Universe film, the question always exists about who knew what direction Marvel was going to go with the story and when.  Consequently, that is the first thing Ellwood talks about with Stan – was he, Stan, aware when he did the first "Captain America" movie of the Winter Soldier storyline and if Marvel was going to be making a movie out of it at any point in the near future.

Stan says that he knew what happened to Bucky in the comics, but wasn't sure if Marvel would be turning it into a movie at any point in the near or distant future.   He was, however, keeping his fingers crossed.

If you watch until the end of the interview, you'll also get a discussion about the post-credits sequence, one which does a good job avoiding spoilers.  Watch, enjoy, and don't forget to tell us your thoughts on the film.

"Captain America: The Winter Soldier" is currently in theaters around the globe.
