Back in October, we reported that Marvel and ABC are planning a Marvel's Agent Carter TV series centering on Peggy Carter, played by Hayley Atwell in 2011's Captain America: The First Avenger. While doing press for Captain America: The Winter Soldier, writers Christopher Markus and Stephen McFeely offered new details about the hour-long drama, revealing that their pilot script has been written and that Hayley Atwell is interested in returning as Peggy Carter, with the series set in the year 1946, in the middle of the same timeline established in last year's short film Marvel One-Shot: Agent Carter.

When asked about the status of the project, Stephen McFeely revealed that the pilot still doesn't have a green light yet, but they both love the script, and Hayley Atwell is interesting in coming back.

"It's a big maybe. The script turned out great, we all think so, and those at ABC and Disney think so, and I think it's in ABC's hands. She's (Hayley Atwell) game and on board."

He also revealed that Dominic Cooper will have a recurring role as Tony Stark's father Howard Stark, a character he played in both Captain America: The First Avenger and Marvel One-Shot: Agent Carter. Christopher Markus added that the show would be set in the middle of the Marvel One-Shot: Agent Carter timeline in 1946.

"If you cut the One-Shot directly right down the middle, and you don't get to the next morning, you've got a whole show in there."

Stephen McFeely adds that they wanted to keep Peggy in this S.H.I.E.L.D. world for a longer amount of time.

"It's so good. Everyone saw (the One-Shot) and it's so clearly a series. We can't get her to the end of S.H.I.E.L.D. that fast. We wanna stay in that world longer where people are disrespecting her and she's proving herself and going on missions and things like that. I just really want it to go. It has not officially been green lit, but it's not dead by any stretch."

Despite the fact that this is being developed for a major network, Stephen McFeely revealed that they envision the show running for 13 episodes or less each season, perhaps even as a summer series like Under the Dome.

"[13 episodes] is how this is envisioned, maybe even less...That's my hope, is that it would be something like [Under the Dome]. Our case would be that it would be a limited series and you would wrap up that one bad guy and that one case, and then if you like it we'll do it again next year and it's 1947."

We reported in January that Reaper creators Tara Butters and Michele Fazekas will serve as executive producers and showrunners if the series is ordered.
