The new companion, starring opposite Matt Smith when Doctor Who returns for a full series in Spring, 2010, has been revealed!
She has appeared previously in Doctor Who, playing the Soothsayer in the Tenth Doctor adventure, The Fires of Pompeii. In that episode the Doctor admits, 'I sometimes need someone' and from 2010 that someone will be Karen Gillan!
After winning the coveted role, Karen, 21, announced, 'I am absolutely over the moon at being chosen to play the Doctor's new companion. The mostrar is such a massive phenomenon that I can't quite believe I am going to be a part of it.'
