The BBC released the official DOCTOR WHO trailer for Series 9 at San Diego Comic-Con today, but it was also made available online. I've embedded it above. Not bad, eh? At this stage in the show's history, it's harder for me to be blown away -- and this year doesn't have a new Doctor or companion to promote -- but the promo does have a different feel. Darker, a bit edgier. I'm sure there are lots for the eagle-eyed experts to spot, but obviously there's the return of Missy/The Master (Michelle Gomez), the shapeshifting Zygons, the faithful Daleks. And who is Maisie Williams from Game of Thrones playing? Could she be The Doctor's granddaughter? The twelve-part ninth series begins 19 September on BBC1/BBC America, which means it will end mere weeks before the Christmas Special airs.
