What can you say about Sharon’s motivations to take the side that she does? Last we saw her, she was starting to work for the government at the end of “Captain America: Winter Soldier,” so what brings her to where she is here?

When we find her, she’s working in Berlin, the Joint Terror Taskforce. We meet her at Peggy’s funeral and that’s where Steve finds out sort of who she really is, because it was never mentioned in “The Winter Soldier.” That’s sort of the beginning of when the whole Accords thing is happening. So she sort of finds herself a little bit between a rock and a hard place in terms of her loyalty to Cap.

But, obviously, he’s rebelling against the Accords and she’s just sort of trying to help him and continue to keep her job. Because she’s feeding him information that she’s obviously not allowed to be feeding him and you really get a sense of her loyalty to him, which I think is interesting and something that I loved about their relationship in the comic books.

This is your second time working with the Russo brothers. Can you describe what it’s like, working with them and how working with a pair of directors feels different than working with a single director?

Absolutely. I mean, this is my second time working with the brothers. I worked with brothers on “Carriers” and honestly, I think it’s an amazing way to work. I mean, they obviously are brothers so they have a tremendous rapport.

But with a movie of this scale, it kind of is amazing to have two people that, one person can be focusing on one thing, one person can be focusing on the other. So they really get great performances. They get great effects and it’s double the power, you know what I mean? So to keep this huge engine moving, it really helps to have two people. They are both brilliant and kind of extraordinary in their own way.

Honestly it’s a huge bonus and they’re great guys and really fun to work with, so it’s like a win-win all the way around.

What new things can audiences expect from your character in this film that they might have gotten specifically in “The Winter Soldier?” Without giving spoilers, obviously.

We were really planting a seed in “The Winter Soldier.” Cap didn’t even know that she was Sharon Carter, within that film. Steve finds out who she is — and that, I think, just inevitably deepens their connection because of obviously the shared tie with Peggy. There’s just an inevitable, immediate trust between them. And we really explore that throughout this film, and we see that the stakes are high for her because, her job is at stake if she’s helping Cap. That’s the bottom line, but we really see her sort of follow her heart rather than her head, I suppose, which is cool.

Did you do any research via comic book reading in preparing for your character? And have you been a past fan or a reader of comics?

I was not a fan, previously, but when I joined the universe as Agent 13, they handed us all of these bibles, which is everything. I learned everything Sharon Carter and I just sat with it and went to town and really kind of fell in love with Sharon and her relationship with Cap. And it’s really interesting because all of the comic books are different; their stories are different. Her relationship to Peggy varies from comic book to comic book, but it’s fun to kind of take elements of all of the different stories and really piece together a character that hopefully the fans enjoy. It’s a really interesting process, because you don’t always have that kind of information readily available when you’re researching for a part, so it makes it a really cool process.

Marvel recently released this featurette highlighting the company’s achievement in adopting more women roles in their movies. In addition, you were also involved in in the “Captain America: Civil War” Challenge for young women in STEM. What are your feelings on playing the strong female role, and empowering women across the country in the process?

I mean, that’s just a huge compliment to hear that. These characters are so much fun to play, but to know that in doing this, it could be you potentially empowering young girls, is amazing. And I think Marvel’s really trying to diversify and they’re really sort of incorporating more women in these great parts, and I think it’s just kind of heading in the right direction, you know? But it’s super-enjoyable to play, too.

This is your second time playing this role. What, if anything, are you doing differently this time in terms of how you’re playing your character?

I think when we met her in “The Winter Soldier,” she was kind of at a rookie stage. She was figuring out what her feelings on everything were like, where her loyalties lie and all of that. So we just sort of scratched the surface, really. I mean, we didn’t even know she was Sharon Carter, so I got to have a lot more fun in terms of just being genuine to the character. Her openly being Sharon Carter, Cap knowing she’s Sharon Carter, it kind of allowed us to delve into their relationship a little bit more and really dig into where her loyalties are. It’s just really fun to play, now that it’s not hidden, who she is, it can kinda just go there with her. And all of the research that I did on her, and all of the ways in which I admired their relationship in the comic books, we got to play that out a little bit, which was great.

This is a “Captain America” film, though it does have quite a few other Avengers in it. How do you feel that the film differentiates itself from the previous two “Avengers” films, and makes itself truly a new “Captain America” movie?

It’s interesting. It does really feel like “The Avengers.” Everybody is in it, pretty much, [laughs] so it is hard to differentiate it, but they really are kind of focused on the relationship between Tony and Steve and what they represent. And the rest is people picking sides. They really delve into the depth of what these two characters within the universe truly, truly feel and they are the extremes of those feelings that, you know, other people are kind of following, so it still does feel like a “Captain America” film.

What makes this film stand out from other Marvel films?

I just feel like each movie gets better and better. It’s amazing to me. This film is just absolutely epic, from introducing these great new characters to these epic battle scenes, it’s just taking it to a whole other level. The Russo Brothers did an extraordinary job with it, so not to put down any of the other films, which are amazing, but I just feel like this is kind of the biggest one they have done yet. And that’s kind of what Marvel does. They never, never disappoint. So, hopefully everyone loves it as much as I did.

“Captain America: Civil War” hits theaters this Friday, May 6th.
