Doctor Who star Peter Capaldi has signed up for a second series as the Time Lord, a newspaper report has claimed.

The 56-year-old actor - whose first full episode as the Doctor premiered in Cardiff and London yesterday - has been locked up in a deal which will also include a Christmas special episode, The Sun reports.

An unnamed source is quoted as saying both Capaldi and the Beeb were keen for him to continue in the role.

Five thousand fans are believed to have packed the streets of Cardiff for the screening of Deep Breath, reviewed by the Mirror’s TV editor here.

Peter and co-star Jenna Coleman are set to visit five continents in 12 days before the new series starts on BBC1 on August 23.

The Thick of It star Peter said he will be channelling all the previous Doctors he grew up watching .

“I was brought up on Doctor Who. They are all in me,” he said. “They taught me how to act because I spent all my time trying to be them.”

Speaking to fans for the first time since landing the role , he defended his right to play the Doctor at the age of 56, following on from Matt Smith, 31, as the youngest-ever Time Lord.

He sniffed: “I think too much is made of my age. Who cares? Doctor Who is over 2,000 years old.”

But he concedes he is both frightened and apprehensive as he waits to see how he will be received by the show’s enormous global army of fans.

“If there are a lot of people who don’t like me there will also be some people who really like me,” he said.

“That’s the nature of the show. People will take sides. They can look forward to a Doctor who is difficult to keep up with, and who is more alien than perhaps we’ve seen for a while.”
