The 56-year-old actor played the iconic sci-fi character in one series when 'Doctor Who' returned to TV screens in 2005 and has reprised the role for a new audio drama and has been having a great time recording his parts.

Executive producer Nick Briggs told "He’s really joyous about it. He said within two minutes of doing it, he was back in the zone, back there with the character.

"And he was very flattering to me – I’d written the script. He said, 'You’ve really captured the character as I played him and it’s the way he spoke.'

"‘It’s been really lovely, actually. He’s made us laugh a lot. And he’s been singing quite a bit as well. He’s a real music enthusiast."

Nick also voices the Daleks and gave Christopher and Billie Piper a shock when they arrived late for a read-through one day.

He explained: "[Christopher] tells the story of how, when he came rushing into a read-through that he and Billie Piper were late for, they didn’t see me with my microphone.

"And then he got to the scene, the first scene with the Dalek, and I started doing the voice and my voice was coming out of a speaker with the effect on and he said he and Billie jumped out of their skins [like] 'What on earth is going on?!' And the whole room burst into spontaneous applause. "

Christopher quit 'Doctor Who' after just one series, and he previously slammed the BBC's handling of the situation.

He said in 2018: "What happened around 'Doctor Who' almost destroyed my career.

"I gave them a hit show and I left with dignity and then they put me on a blacklist. I was carrying my own insecurities as it was something I had never done before and then I was abandoned."

Christopher actually decided to leave the UK in order to progress his career.

He explained: "I was told by my agent at the time: 'The BBC regime is against you. You’re going to have to get out of the country and wait for regime change.'

"So I went away to America and I kept on working because that’s what my parents instilled in me. My dad always said to me: ‘I don’t care what you do - sweeping the floor or whatever you’re doing - just do the best job you can.’ I know it’s cliched and northern and all that b*******, but it applies."
