Sheridan Smith

Sheridan Smith (born 25 June 1981) played Lucie Miller, companion to the Eighth Doctor, who debuted in the Big Finish production for BBC Radio, Blood of the Daleks. She can therefore fairly be said to have played a "radio companion", not merely an audio one. In fact, she is certainly the only actor to originate a recurring, lead role in Doctor Who on radio.

Outside Doctor Who, she is likely best known as one of the stars of the long-running programme alongside Kathryn Drysdale. She also starred with Paul McGann in the 2010 Easter special, "The Judas Tree".
