HBO Max Scores Exclusive ‘Doctor Who’ Streaming RightsJo Tro Do Plo Plo No: ‘Doctor Who’ Welcomes Back Familiar Monster Stay on target Let us know what you like about Geek by taking our survey. There’s a lot to be excited about this Christmas. (And I don’t just mean food, family, or a pile of gifts.)On Dec. 25, Peter Capaldi returns for his final act as the Twelfth Doctor—who meets the First Doctor (David Bradley as William Hartnell) and regenerates into the Thirteenth Doctor (Jodie Whittaker).The timey-wimey Yuletide episode follows the events of season 10 finale “The Doctor Falls,” when Bradley’s character appears in a snowy field outside the TARDIS, confronting his current incarnation.Little is know about the festive next chapter, penned by exiting showrunner Steven Moffat and directed by frequent collaborator Rachel Talalay (currently helming an upcoming episode of Riverdale).Starring Capaldi, Bradley, Pearl Mackie, and Mark Gatiss as The Captain (with a possible reappearance by Jenna Coleman’s Clara Oswald), “Twice Upon a Time” will introduce the first female Doctor—Jodie Whittaker.David Bradley as William Hartnell as the First Doctor (via BBC)“We worked together on Broadchurch. She’s lovely,” Bradley told Doctor Who Magazine of his sort-of co-star.The ITV crime drama, which stars Tenth Doctor David Tennant, the incomparable Olivia Coleman, and Whittaker as grieving mother Beth Latimer, featured Bradley, playing local shopkeeper Jack Marshall, in five episodes.“[She is] absolutely delightful,” he said in praise of Whittaker. “I think she’ll be fantastic. All the emotional range you could want, and she’s going to be very funny as well.“So she’s perfect for the Doctor, really.”And he should know—he is the Doctor.Perhaps best known as Hogwarts’ cantankerous caretaker in the Harry Potter films, Bradley first appeared in the 2012 Doctor Who episode “Dinosaurs on a Spaceship” (written by new Who showrunner Chris Chibnall), before portraying the late Hartnell in 2013 TV movie An Adventure in Space and Time, about the creation of Doctor Who.“I was playing the guy who was playing the Doctor, but now I’m the Doctor,” he said in DWM. “It’s absolutely thrilling.”Doctor Who Magazine cover story David Bradley (via BBC)Not expected to return to the BBC program after this Christmas, Bradley will continue his tenure as the OG Time Lord in Big Finish’s upcoming audio collection, “The First Doctor Adventures: Volume 1” (available to pre-order now).But that hasn’t stopped him from lauding Chibnall, who created and wrote all three seasons of Broadchurch.“He’s just wonderful. His scripts are so rich and fascinating. Well-drawn, forceful characters,” Bradley said.“As an actor, working with Chris, you feel you’re in very good hands. As you do with Steven [Moffat],” he continued. “We’re all in it together on Doctor Who, and everybody wants it to be good. I think Chris will be amazing.”As was done when Russell T. Davies handed the series over to Moffat in 2010, Chibnall wrote all of the Thirteenth Doctor’s dialogue.Tune in to BBC and BBC America on Dec. 25 to see what she has to say. (Don’t forget to stock up on tissues!)Together with some old friends—including Ben Jackson (Jared Garfield) and Polly Wright (Lily Travers)—the two Time Lords must save the world before each takes a new shape: Bradley into Second Doctor Patrick Troughton, and Capaldi into the Thirteenth Doctor.
