Hayley Atwell's Peggy Carter was a beloved character in Captain America. So much so, that many fans were disappointed that Captain America: The Winter Soldier would take place in the present, and thus have no room for Carter.
Luckily, Marvel has announced that Peggy Carter will appear in The Winter Soldier, in flashback scenes to the WWII storyline.
That may not be the end of Peggy, however, as Atwell recently told The Age, "As part of Comic-Con there will be a little kind of snapshot as to what Peggy’s actually really capable of...Hopefully, it will lead to other things."
What that means is unclear. Could Atwell be a part of a Marvel One-Shot, the short films released as part of the Marvel movie DVDs? Or Might she get her own feature at some point?
Atwell would like it to mean a full-fledged movie. "I'd revisit Peggy again...I'd like to, if I get a spin-off, definitely add a bit of humor in there. She's very British. Very uptight. Let's hope if she gets a spin-off it's modern day, so she can relax a little bit, let go of the uniform."
