The 26-year-old actress revealed a little bit about the next installment of this series, which is entitled 'Hide.' "We are in a haunted house in the '70s with Dougray Scott and Jessica Raine," she told Redeye. "And it's scaaary." In images released by the BBC of Saturday's upcoming episode, the show's star Matt Smith and Coleman's character Clara look a little spooked out as they go on a ghost hunt in an abandoned mansion on a desolate moor.

In one particularly scary photo, the Doctor appears to have turned into a ghost himself as Clara fades away in the background. Speaking about Colemans contribution to the popular TV show, writer Steven Moffat said: "What Jenna in particular brings is she has a tremendous speed and wit and sort of an unimpressed quality that makes the Doctor dance a bit harder, I suppose, he works a bit harder with Clara." "Clara is secretly devoted to him but a little bit harder to impress. There's a real sense of toughness; [she's] someone who can be a real adversary if she wants to be. "That's very much driven by Jenna's particular style," he added, "which is it's a very, very fast, snappy style." 'Hide' will be shown on BBC1 this Saturday at 6.45pm.
