Steven Moffat has stated that a ninth series of Doctor Who will air next year.
Like the show's upcoming eighth series, the 2015 episodes will air as a single uninterrupted run, Moffat told Doctor Who Magazine.
"We're not going to do splits [in series eight], and the same format will repeat exactly the following year like that - so it will be the traditional form," said the sci-fi drama's head writer.
Doctor Who's eighth series - the first to star Peter Capaldi as the Doctor - is expected to air on BBC One from August.
Filming on the new episodes began this week, with a first-look image of Capaldi on-set with co-star Jenna Coleman (Clara) unveiled on Tuesday (January 7).
The first two installments will be helmed by Sightseers director Ben Wheatley.
