The relatively unknown actor is taking over the Tardis from David Tennant and will first appear on screens as the Time Lord in 2010.
“This show is so alive, it really is,” he said in an interview with Doctor Who magazine.
“I can’t ever quite forget that I’m the Doctor – which is weird, because it’s still so far away. But it’s always there in my subconscious, because it’s the Doctor!”
Matt – who at 26 is the youngest of all 11 Time Lords since the series started in 1963 – went on: “It’s like, there’s Sherlock Holmes, James Bond and Doctor Who. It has resonance in our cultural fabric.”
The actor also hinted that the Doctor’s style might change to reflect his own tastes.
Asked what he might wear as the Doctor, he said: “I’m a big fan of long coats and rather dashing scarves in everyday life, so who knows? For the audition, I rocked up in whatever, so I think they’re having to tone down what I wear in real life for the Doctor!
“I am a rather elaborate dresser. That’s what’s lovely, there are all these exciting things – what’s he going to wear, what’s he going to do in his first scene with his companion, which monsters will he meet, will he meet the Daleks?”
