Career: Coleman went on to have a recurring role in Waterloo Road, but claims that playing a schoolgirl at the age of 23 was 'surreal'. She went on to appear in Julian Fellowes' ITV mini-series Titanic and starred in a BBC Four adaptation of John Braine's novel Room at the Top. She made her film debut in Captain America: The First Avenger (2011). Her profile increased significantly in 2012 when it was announced that she would play the companion in Doctor Who. Away from the sci-fi drama, she has starred in Stephen Poliakoff's Dancing on the Edge and the three-part drama Death Comes to Pemberley. In 2013 she dropped 'Louise' from her name and is now known as Jenna Coleman.
