Marvel is once again delving into the television realm tonight on ABC with their new 7 part mini-series, Agent Carter.

Agent Peggy Carter (Hayley Atwell) is one of the founding members of S.H.I.E.L.D., and is so much more than just Captain America’s girlfriend.  Marvel was kind enough to share this behind-the-scenes featurette ahead of tonight’s premiere:

And don’t forget!  The human-sized Ant-Man trailer will make it’s debut during Agent Carter!
