Steven Moffat's TV adaptation of Audrey Niffenegger's sci-fi romance novel The Time Traveler's Wife has been ordered to series at HBO. First published in 2003, the novel was adapted into a film starring Eric Bana and Rachel McAdams in 2009, and at one point a TV series was in development at ABC, though it never made it to production.
As the title suggests, The Time-Traveler's Wife is about a woman, Clare, whose husband Henry suffers from a genetic condition called Chrono-Impairment, which causes him to involuntarily travel backwards and forwards through his own timeline. As a result, when Henry meets Clare for the first time she has already met him many times throughout her life.
A press release from HBO describes the upcoming series as "An intricate and magical love story [that] tells the story of Clare and Henry, and a marriage with a problem… time travel." The series will be written by Moffat and executive produced by Sue Vertue (Sherlock) and Brian Minchin (Doctor Who). The press release was accompanied by this statement from Moffat:
“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.”
In the Doctor Who episode mentioned by Moffat, "The Girl in the Fireplace," the Doctor finds a fireplace on board a derelict spaceship, and realizes that it's a portal to eighteenth century France, opening up in the bedroom of a little girl called Reinette - who is actually the young Madame de Pompadour. The Doctor travels through a series of time windows to various points in Madame de Pompadour's life, and she eventually falls in love with the mysterious man whom who has known all her life. Also, because this is Doctor Who, there are clockwork androids who want to steal her brain.
Moffat recently departed Doctor Who after a decade as the series' showrunner, and he and Mark Gatiss' modern adaptation of Sherlock is currently in the middle of one of its lengthy hiatuses, freeing him up to work on The Time-Traveler's Wife. According to Deadline this particular project was highly sought-after, with Amazon also making a bid for it. HBO has a reputation for creating prestige TV shows like Game of Thrones and Westworld, so a TV show based on The Time-Traveler's Wife probably couldn't have asked for a better home.
