Matt Smith! Who is he? A fairly young actor and a bit weird looking.
Here's more from
BBC News
Matt Smith has been named as the actor who will take over from David Tennant in Doctor Who - making him the youngest actor to take on the role.
At 26, Smith is three years younger than Peter Davison when he signed up to play the fifth Doctor in 1981.
Smith will first appear on TV screens as the 11th Doctor in 2010.
He was cast over Christmas and will begin filming for the fifth series of Doctor Who in the summer. Tennant is filming four specials in 2009.
Smith was named as Tennant's replacement in Saturday's edition of Doctor Who Confidential on BBC One.
He said: "I've got this wonderful journey in front of me where I've got this six months to build this Time Lord - and that's such an exciting prospect."
