Fans of Captain America: The First Avenger and Marvel One-Shot: Agent Carter are in for a treat early next year when Marvel's Agent Carter debuts on ABC, in an eight-episode run that will bridge the gap between the first and second halves of Marvel's Agents of S.H.I.E.L.D.'s second season. Hayley Atwell returns as the title character, Peggy Carter, who revealed new details about the show in an interview with TV Line.

When asked if it was always the plan to make a TV series after the Marvel One-Shot: Agent Carter short film, here's what the actress had to say about the show's development.

"It wasn't on the agenda. It was just something that (Marvel's) Louis D'Esposito had done before, and he wanted this to be sort of an epilogue to Peggy's story from Captain America: The First Avenger, which was sort of left in the 1940s. We did it (the short) in a week and a half and just had a good time doing it. It was just based on the success of the One-Shot and the press and the fans loving it so much that we decided, last year at Comic-Con, that it might be something we should try and develop. It's been in the making for a year now. The official green light from ABC happened back in May, and I was kind of delirious. It was just wonderful, because it's been such a dream project so far. You don't get the opportunity in this industry, too much, to revisit a character that you've enjoyed, with a group of people you've loved working with. It's become the gift that keeps on giving."

When asked what her favorite part of the eight-episode series has been thus far, Hayley Atwell had this to say.

"My favorite part is something the audiences haven't seen yet. It's the development of her character throughout the series which will be someone who is kind of more three-dimensional, something that women can relate to, as not just the competent, strong, intelligent woman in this workforce, but the psychological, emotional cost. What it takes for a woman to have to sacrifcie personal relationships in order to find her place in the world and to fulfill her kind of destiny. That's something that I find really interesting, as a character study, and I think that's something the audience will really respond to."

The actress also revealed that shooting starts in September, while teasing the training regiment she has to undergo in a short period of time.

"We start end of September, so I have 10 weeks to do a lot of physical training to be able do the stunts and all the combat that's going to be required of me, as well as the stamina to be shooting five days a week in quite intense conditions. It will be a lot of strength training, lots of interval training, lots of running, and then lots of stunt coordination work with some supervisors, just making sure I'm not going to hurt myself. I made a big thing of wanting to do as much stunts as is legal, because I thought I'd be a big fake if I didn't at least try them all, so as long as they allow me to do as much as I can, I'm ready and I'll be up for it."

Since the series is only eight episodes long, the actress was asked if there will be a procedural element. Here's what Hayley Atwell had to say in response.

"It's still under development at the moment. I've only read the pilot, which is brilliant. I think the idea is, because it's eight episodes, it's going to be a very contained, intense adventure, lots of twists and turns along the way. There isn't much time for it to breathe or become too diluted or drawn out. It's going to be a lot of adventure, a lot of action, as well as driving the plot along of this girl struggling to form this better world for herself and the people around her. It's going to be a very tight ship that she runs, and I think, because of the nature of the genre, it's possible that it's going to take a lot of exciting turns."
