Moffat reveals new 'Who' details

Steven Moffat has revealed details of the upcoming sixth series of Doctor Who.

The writer told Den of Geek that he would be writing five episodes for Matt Smith's second run as The Doctor.

He said: "I’m doing the [2010] Christmas special plus five, so it’s the same. Six again."

Moffat explained that since taking over as showrunner on Who, he had continued to follow the writing schedule of former boss Russell T. Davies.

"I’m basically following what Russell did," he confirmed. "Having worked out the sums and worked out how he does it, I thought that’s a perfect way of doing it."

He also admitted that he was struggling to maintain a balance between working on Who and producing new BBC drama Sherlock.

"The last year has been extraordinary," he claimed. "I’ve had about four days off, and that includes Christmas day. I work every weekend, I get up early in the morning, I go to bed late at night. There is no way of balancing it."

He added: "It’s extraordinary, but it’s great fun too! Great fun, so long as it doesn’t kill me!"

Doctor Who returns to BBC One this Christmas for a one-off special, with a new series to follow in 2011.
