Was Agent Carter cancelled so that ABC could use actor Hayley Atwell elsewhere? That's what really happened according to Atwell, in a frank interview with IGN.
"You know Marvel and all the creatives behind the making of the show loved it. And we loved it. We all loved making it. It was a network political thing," said Atwell, referring to ABC. "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."
Atwell was officially cast for Conviction in February 2016, which was during the second season of Agent Carter. ABC passed on renewing Agent Carter for a third season just a few months later, and Conviction debuted in October 2016 but was cancelled soon after.
Marel Television head Jeph Loeb has said ABC didn't engage in any conversation with Marvel about renewing Agent Carter, and said he didn't know why they cancelled it.
"There were no conversations," Loeb said in September 2016. "We had a call from the network. The network said they were cancelling the show."
Since the cancellation of Agent Carter, Atwell's Carter character was killed off off-screen in 2016's Captain America: Civil War. That being said, Atwell reprised her role for the animated Avengers: Secret Wars and would "love" do more films as Carter for Marvel Studios.
"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," said Atwell. "I'd love to see [Peggy] more in films. 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."
