Audrey Niffenegger's hugely popular 2003 novel 'The Time Traveler's Wife' is being adapted for TV - and the man behind 'Doctor Who' and 'Sherlock' will be writing it.

The book - about a man with a genetic disorder that means that he is a time traveller that can be whisked away at any moment, and the wife that he constantly leaves behind - has already been adapted for the big screen in 2009, starring Eric Bana and Rachel McAdams.

However, this new adaptation will be written by Steven Moffat after being green-lit by HBO.

Moffat said: "I read Audrey Niffenegger’s The Time Traveler’s Wife many years ago, and I fell in love with it. In fact, I wrote a Doctor Who episode called 'The Girl in the Fireplace' as a direct response to it. When, in her next novel, Audrey had a character watching that very episode, I realised she was probably on to me. All these years later, the chance to adapt the novel itself, is a dream come true. The brave new world of long-form television is now ready for this kind of depth and complexity. It’s a story of happy ever after — but not necessarily in that order.”

Casting has not yet begun, and other details like premiere date and how many episodes will feature in the series have yet to be revealed - but given who's behind it, this could be very promising.
