Agent Carter, the “Marvel One-Shot” video short featured on the DVD and Blu-ray releases of Iron Man 3, brings back Captain America: The First Avenger’s Peggy Carter, portrayed by Hayley Atwell. The story, directed by Marvel Studios co-president Louis D’Esposito, highlights the start of Carter’s life as a secret agent following the events of the first Captain America movie.

According to Deadline’s Nellie Andreeva, though, it might not be as much of a one-shot as a precursor of things to come.

“The ‘one shot’ short films featured as extras on Marvel movies’ DVD releases are becoming a hotbed for TV series ideas. After one such short, Item 47 on The Avengers DVD about the agents of S.H.I.E.L.D., led to the new ABC/Marvel series, another one may also spawn a series project for ABC. Marvel is notoriously secretive about their development, and no one would comment, but I hear the company is working on a concept for a potential TV series inspired by Agent Carter, a one shot, which will be featured on the upcoming Blu-ray release of Iron Man 3,” Andreeva wrote.

Iron Man 3 will be released on Tuesday, September 24, 2013, the same day Marvel’s Agents of S.H.I.E.L.D. debuts on ABC.
