Before joining Doctor Who as companion Clara Oswald in 2012 (she's soon to become the longest-running companion of the new series by the end of Series Nine), Jenna (formerly Jenna-Louise) Coleman had a steady career including regular roles in English soap operas Waterloo Road and EastEnders. Oh yeah, and a cameo in Captain America. Thats right, one of the Impossible Girls splinters in time apparently materialised in 1940s America. Jenna doesn't have a huge role in the film but features in the scene in which a pre-Cap Steve Rogers and Bucky Barnes go on a double date to the fair.
