Speaking ahead of his Doctor Who appearance, Stephen Fry says: “Short of being picked for a British space exploration programme and I readily concede that I’m past the age where I’d be considered (if I was ever the right age for such a posting) - then being in an episode of Doctor Who will certainly do as a very sweet second-place excitement.”

Sir Lenny Henry CBE says: “It was absolutely brilliant to be welcomed into the fantastical world of Doctor Who. The nearest I have been to the TARDIS was when I played the Caribbean Doctor in the Lenny Henry Show, so as a life-long (hiding behind the sofa type) Doctor Who fan this is a very special moment for me.”

Chris Chibnall, Showrunner, says: “Doctor Who is coming back with a bang - with two great British icons in major roles. One of the great joys of Doctor Who is getting to work with actors from your wish list. Stephen and Lenny are two of my absolute favourite actors - and to be able to bring them into Doctor Who, in one of our biggest ever stories to kick off the new series, is an absolute thrill.”

Doctor Who will return in early 2020.

Jodie Whittaker will reprise her role as the Thirteenth Doctor alongside Tosin Cole (Ryan) Mandip Gill (Yaz) and Bradley Walsh (Graham) who are all returning for their second series.

Chris Chibnall returns as Showrunner with Matt Strevens as Executive Producer.
