Neil Gaiman’s second Doctor Who episode will air next spring. Stephen Woolfenden, a second unit director on some of the Harry Potter films, is helming the episode. The episode will also co-star Warwick Davis, Tamzin Outhwaite and Being Humans Jason Watkins. The full run of eight episodes to season seven will air in the spring, presumably meaning season eight starts in the fall. The Cybermen were the product of an alternate universe full of zeppelins in “The Moonbase””]
