Who's next?

David Tennant, the man being tipped to take over from Christopher Eccleston, set his sights on acting at an early age.

Appropriately, Doctor Who and the BBC sci- fi series Blake's 7 were great childhood sources of inspiration for the actor, who is 33. Tennant is widely regarded as a rising star of film and TV and is playing the lead role of Casanova alongside Peter O'Toole in the BBC drama. He will also hit the big screen later this year in Harry Potter and the Goblet of Fire.

The son of a church minister and the youngest of three children, Tennant was raised in Renfrewshire, Scotland.

In a recent interview, he revealed that he told his parents when he was three that he intended to act.

At 17, he entered the Royal Scottish Academy of Music and Drama in Glasgow where actors Emma Fielding and Greg Wise were classmates.
