“Doctor Who is the most exhaustingly planned show on earth.” So says the show’s lead writer and executive producer, Steven Moffat, in an interview today. Moffat admits that he encounters few surprises when putting together the show that encompasses all of time and space but there are plenty of surprises for the audience.
The second part of season 7 begins with The Bells of Saint John, which will kick off Jenna-Louise Coleman’s run as the Eleventh Doctor’s (Matt Smith) newest companion. Speaking about Coleman, Moffat said Clara brings a wit and unimpressed quality to the TARDIS and the Time Lord that makes the Doctor work harder to be impressive. “They have enough in common and yet enough sharp contrast,” said Moffat, referring both to the Doctor and Clara as well as Smith and Coleman.
Adding to the uniqueness of Clara is that the Doctor has already met two other versions of his new companion. Regarding whether Clara will ever remember or learn about those other encounters, Moffat jokingly replied, “I would know the answer to that question and certainly won’t give it to you.”
