Author Neil Gaiman slipped out some details about the Doctor Who episode he penned for the next season, Entertainment Weekly reports.
“Classic Doctor Who episodes are always filmed at some point in a quarry, and I’m incredibly pleased to say they have spent the last week filming in a quarry, in the rain, which is awesome.”
Also, a character played by Suranne Jones named Idris will appear in the episode.
"(Idris) may very well be an old acquaintance of the Doctor with a new face.”
Female, old acquaintance, new face... Is the Rani finally returning? We'll find out sometime around Easter next year.
