Peter Capaldi says Doctor Who is in his DNA.

The Thick Of It star recently took over as the Time Lord from Matt Smith and said that he felt closely connected to the part.

He told Doctor Who Magazine: “I was five when the show started. I don’t remember Doctor Who not being part of my life, and it became a part of growing up, along with The Beatles, National Health spectacles, and fog. And it runs deep. It’s in my DNA.”

Peter admitted it had been an odd experience being revealed as the 12th Doctor on live TV, but said he had enjoyed it.

“Admittedly, it was somewhat outside of my comfort zone to be revealed in that way, but that’s the way it fell,” he said.

“I was nervous about the ‘Tonight, Matthew, I’m going to be Doctor Who’ element.

“It seemed a million miles away from the actual job. However, in the end, I kind of enjoyed it. A little showbiz never hurt anyone. And Zoe Ball was great.”

The 55-year-old actor said people shouldn’t judge the quality of special effects in early series too harshly.

He explained: “People look at them now and, understandably, mock the bargain-basement monsters, and the accidents and collisions that came from having virtually no time in the studio to shoot fantastically ambitious stories.

“But those old shows were only made to be watched once, on a flickering monochrome telly that smelled of valves and furniture polish. In that context, they succeeded immeasurably. They were triumphs of imagination.”
