Steven Moffat says Peter Capaldi was the only name on his list of replacements for Doctor Who star Matt Smith.
Asked if he’d had a short list, Moffat said: "Yes. The list went 'Peter Capaldi'. It was a very short list."
Speaking backstage after tonight’s live reveal of the new twelfth Doctor, Moffat said he had been considering Capaldi for some time and that the star’s love of Doctor Who had been a significant factor in his casting.
“[He came on the radar] a fair amount of time ago. I happened to know he's a big fan,” said Moffat. “There's something very seductive about an utterly brilliant, arresting looking leading man actor – one of the most talented actors in Britain – who you happen to know is a big fan of the show.
"You start to think 'maybe we should so something about that'."
Capaldi was unveiled as the new Time Lord tonight during a special BBC1 programme, Doctor Who Live: The Next Doctor. He will take over from Matt Smith at the end of the year, with the incumbent Doctor set to regenerate during the Christmas episode.
Capaldi has been a fan of Doctor Who since it began, even seeing a letter of praise for the show published in Radio Times magazine when he was just 15 years old.
