Earlier this month, we learned that Hayley Atwell would not only be reprising her role as Agent Peggy Carter in ‘Captain America: The Winter Soldier’, but also in a brand new Marvel: One-Shot short film titled ‘Agent Carter’. The ‘Iron Man 3’ Blu-ray exclusive screened in full at San Diego Comic-Con followed by a special Q&A session with Atwell and director Lou D’Esposito for a lucky few, but now the general public gets a sneak peek at the film before it’s released in September.

Set one year after the events of ‘Captain America: The First Avenger’, Agent Carter has found herself working a desk job for an organization that eventually become S.H.I.E.L.D. under a chauvinist boss played by Bradley Whitford. But when a call comes in while she’s the only one in the office, she goes off to find the mysterious Zodiac on her own. Check out the first clip below:

Are you excited to see Peggy Carter back in the Marvel Cinematic Universe? Is this Marvel One-Shot an extra incentive for you to pick up ‘Iron Man 3’ on Blu-ray? Sound off in the comments.

‘Agent Carter’ starring Hayley Atwell, Bradley Whitford, Shane Black, Dominic Cooper, and a few other surprises will be released on the ‘Iron Man 3’ Blu-ray on September 24, 2013.
