Peggy Carter (Hayley Atwell) has been spotted on the Captain America: The Winter Soldier set in Cleveland, Ohio, USA, on Thursday, 19 June.
The house, located at 2178 Harcourt Drive, will stand-in for a nursing home for Peggy. According to a crew member, the scene is expected to last a brief two minutes in the film.
An additional picture of Chris Evans as Steve Rogers can be found at the source.
