Hayley Atwell reprises her role as Peggy Carter from Captain America: The First Avenger in the first clip from the short film Marvel One-Shot: Agent Carter, which will be included on the Blu-ray and DVD release of Iron Man 3 on September 24. As we reported earlier this month, the short is set a year after the events of Captain America: The First Avenger, with SSR agent Peggy Carter trying to hunt down a mysterious villain known as the Zodiac. As you can see in this scene, Agent Carter is not one to be trifled with, as she takes out two lowly thugs with ease.
