Bradley Walsh

Dr. Bradley Walsh (born 4 June 1960 ) played companion Graham O'Brien in series 11 and series 12 of Doctor Who.

10 years earlier, Walsh played Elijah Spellman, Odd Bob the Clown and the Pied Piper in The Sarah Jane Adventures, in the story The Day of the Clown.

Walsh is the oldest actor to play an ongoing companion on Doctor Who, though Lindsay Duncan and Bernard Cribbins were older when they played one-off companions Adelaide Brooke and Wilfred Mott, respectively.

Outside of Doctor Who, Walsh is best known for presenting the ITV game show The Chase. He also appeared in Coronation Street between 2004 and 2006 as Mike Baldwin's nephew Danny, and presented Wheel of Fortune, another ITV game show, in 1997.
