No, you haven't missed Captain Americas lost love turning up on the small screen in Doctor Who. To experience Marvel star Hayley Atwell's appearances in the Whoniverse, you have to look (or rather listen) to a different medium. The British actress career rocketed when she appeared as the very capable Agent Peggy Carter in 2009s Captain America: The First Avenger. She has since become a core part of the Marvel Cinematic Universe, with the lead role in TV series Agent Carter and cameos in sequel Captain America: The Winter Soldier and the upcoming Avengers: Age Of Ultron and Ant-Man. But before finding international recognition, Hayley Atwell appeared several times in the Doctor Who audios made by Big Finish, appearing opposite the Fourth, Fifth, Sixth and Eighth Doctors and facing off against the Daleks. Not too shabby, Miss Atwell, not too shabby - but let's hope for a proper on-screen team-up of the Doctor and Agent Carter soon!
