At the age of 26, Matt Smith became the youngest actor to take on the role of Doctor Who and he has proved a huge hit with viewers.
As part of Children In Need, he put up some of the Doctor's clothes for auction.
He has described himself as the "ridiculous Doctor" who wears bow ties, likes fish fingers and custard and has his own catchphrase, "geronimo".
