'Doctor Who' writer: 'New episode is unpleasant'

Doctor Who scribe Matthew Graham has revealed that he was keen to write an "epic" and "scary" episode.

Graham, who wrote upcoming two-parter 'The Rebel Flesh' and 'The Almost People', told Den of Geek that he "wouldn't be surprised" if the BBC airs a warning before the first episode's broadcast.

"I showed it to my wife the other night, and there were a couple of images in it where she went, 'Actually, that's quite scary. That's not very pleasant'," he admitted. "I [also] notice that it's going out a bit later [at 6.45pm]."

The Life on Mars co-creator said that he had partly written the episodes as a "response" to viewers who were disappointed by his previous contribution to the series, 2006's 'Fear Her'.

"[For] those who maybe thought that 'Fear Her' was too childish and too silly, I'm hoping that [this story] will silence them," he said.

Graham also confessed that he is eager to write another episode of Doctor Who in the future.

"I had such a good time on this run that I would love to come back and do some more," he confirmed. "They seem very, very pleased with the [new] episode, so I hope that they'd consider asking me back."

Doctor Who continues this Saturday on BBC One in the UK and BBC America in the US.
