Agent Carter is probably the underappreciated gem of the Marvel Cinematic Universe thus far. A show that not nearly enough people watched that kind of fell apart in its second season that wasn't given the chance to redeem itself in a third. It's a shame because it even ended on a cliffhanger and people would have loved to see more of the origin of S.H.I.E.L.D. and maybe even some more links to the MCU. In an interview with IGN Hayley Atwell is more than open to return to the MCU in her own movie.
"I'd love to see [Peggy] more in films," Atwell said. "I'd love to see her in her own film. And if we can keep evolving it so that she does new things so that I can surprise myself and she can keep surprising me then I'd love to do it. And I feel very privileged to be part of something that people really love and that entertains them. But also, you're going to these conventions and meeting people who've named their son Carter and people who have a tattoo of "I Know My Value," the tagline. She's a force of good and there are a lot of social media sites where girls and guys have come together and become good friends on an international scale because of their belief in some of the values that Peggy talks about. And that provides them with a different connection that a family situation or school situation that they don't really feel they have a place in. That's really cool to me. So I'm very happy to be a part of that world and keep that going."
As for the show Atwell says that everyone involved was in love with it but it was canceled mostly due to studio politics.
"You know Marvel and all the creatives behind the making of the show loved it," Atwell explained. "And we loved it. We all loved making it. It was a network political thing. They wanted to put me in something mainstream [Conviction] to get their ratings up rather than something that was more genre specific. There were a lot of economic decisions behind it and I wasn't a part of the conversation. So we were all really surprised about that because we kind of got the sense that people were liking it. It had this cult following. So I know there've been online campaigns for it and the fact that we know that she lives until the age of 96 means that technically I could be employed for the rest of my life, you know."
We know that Captain Marvel takes place in the 1990's and we're going to see flashbacks in Ant-Man and the Wasp will also see more of the past. We could absolutely see Agent Carter again in some capacity and considering how popular the character still is Marvel would be stupid not to bring her back again.
