Matt Smith was today named as the new Doctor Who, the BBC said.
He becomes the 11th Time Lord since the programme first aired in 1963.
Smith will replace David Tennant at the helm of the Tardis, and is due to first appear on our screens as the revered doctor in 2010.
The 26-year-old will be the youngest Doctor in the long-running series.
He has previously starred in 'The Ruby and the Smoke' and 'Secret Diary of a Call Girl' alongside Billie Piper who played the Doctor's companion Rose Tyler in 33 episodes.
Smith has also appeared in Alan Bennett's play 'The History Boys' at the National Theatre in London, and alongside Christian Slater in 'Swimming with Sharks' in the West End.
He said he was delighted to take on the role.
He explained: 'I've got this wonderful journey in front of me. I've got six months to build this Time Lord and that's such an exciting prospect.'
