Defence barrister Will Burton is the golden boy of his criminal chambers.
He says, "It feels an important thing to do and I'd hate to miss out on it.
I'm only 38 but my parents had had three kids by this age and I have had none yet." Tennant also paid an emotional tribute to his mum Helen, who died of cancer in 2007, insisting he hopes he can be a good a parent as she was.
"Doctor Who" star David Tennant is hoping to start a family in the New Year 2010, because he doesn't want to miss out on parenthood.
The actor is currently dating 24-year-old actress Georgia Moffett, who is the daughter of former "Doctor Who" star Peter Davison, and admits he is ready to settle down with her and become a dad.
And then Burton is persuaded to defend an arrogant psychopath whom all the evidence suggests has sadistically murdered a young woman. I don't want to reveal any more of the plot to BBC1's new three-part thriller, hooked, in a way that perhaps I'm no longer by the real Homeland.
