The 59-year-old actor has portrayed the Time Lord in the sci-fi series for the past four years, but is set to hand the keys to the TARDIS over to the former 'Broadchurch' actress in the festive special this year, and has promised to "talk her through the madness" before the scenes hit television screens so she's prepared for the drama.

Speaking to the Daily Star newspaper, he said: "David Tennant and Matt Smith have been fabulous to me, because some days things can become overpowering and who can I talk to, and those guys do talk to me.

"I hope I can do that with Jodie. I am always here to talk her through the madness."

The news that the new executive producer Chris Chibnall - who will take over from Steven Moffat - has decided to cast a female as the lead received mixed reviews, but Capaldi is pleased that bosses have decided to change things up this year.

He said: "Anyone who has seen Jodie Whittaker's work will know that she is a wonderful actress of great individuality and charm. She has above all the huge heart to play this most special part. She's going to be a fantastic Doctor."

And it's not just Capaldi who agrees with Chibnall's decision to cast Jodie, 35, as producers at the broadcaster can't wait to see how she'll depict the time-traveller.

Piers Wenger, Controller BBC Drama explained: "Jodie is not just a talented actor but she has a bold and brilliant vision for her Doctor.

"She aced it in her audition both technically and with the powerful female life force she brings to the role. She is destined to be an utterly iconic Doctor."
