Set to air as Episode 4 when the show returns for Series 6 this Spring, the episode stars Suranne Jones (Coronation Street) as Idris, Elizabeth Berrington (Waterloo Road) as Auntie and Adrian Schiller (Being Human) as Uncle.
Talking to SFX, Wilson reveals: “It was due to be shot last year but for budget reasons we moved it to this series.”
He added: “It’s an episode that involves quite a big sprawl, huge alien world locations and a new take on a familiar character, which required a lot of work. It’s a big episode, but I think it’ll be one the fans will love. It’s a real love letter to the fans.”
