Gaiman: 'Who ep changed in 20 minutes'

Neil Gaiman has revealed that his upcoming Doctor Who episode has changed dramatically since he wrote the first draft.

Writing on his Twitter feed, the author discussed the instalment's rumoured working title 'The House of Nothing'.

"[The episode] was only called 'The House of Nothing' for about 20 mins in Feb 2009, when it still had a house in it. & some nothing. (sic)" he said.

Gaiman denied that he was disappointed not to be writing for former Who star David Tennant, insisting that Matt Smith's Doctor "is even more fun, sometimes".

He also revealed that his favourite Doctor was actor Patrick Troughton, who played the character's second incarnation between 1966 and 1969.

"There is only one. But Patrick Troughton is MY Doctor," he admitted.

Matt Smith also previously confessed that Troughton was his favourite Doctor.
