Steven Moffat has discussed the shift towards more two-part stories in the new season of Doctor Who.

Season 9 will open with a two-parter written by showrunner Moffat, followed by another two-parter written by Being Human creator Toby Whithouse.

Episodes 5 and 6, titled ‘The Girl Who Died’ and ‘The Woman Who Lived’, are written by Jamie Mathieson (with Steven Moffat) and Catherine Tregenna respectively.

Speaking to Radio Times at last night’s BAFTA nominations party about Season 9’s stories, Moffat revealed: “They’re not all two-parters – sometimes they’re just linked episodes.”

He added: “That 45-and-out rhythm has served us incredibly well for ten years, but there is a slight sense sometimes, about 35 minutes into the episode, you expect the hero music.”

The writer explained: “It’s just making you slightly unsure you’ll get through the story by the time the music comes up. We’ve all got to be on our toes, can’t be relaxed.”

Moffat also hinted that Peter Capaldi’s Doctor will evolve in the new season: “We’re continuing to develop his Doctor which is a thing he’s very keen on. [Peter Capaldi] doesn’t just want to come back being the same Doctor. He wants to move it on.”

Season 9 began filming in Cardiff in January and will air on BBC One this autumn.
