Before I Go To Sleep (2014)

A 40 year old woman (Nicole Kidman) suffers from anterograde amnesia. She wakes up every morning with no memory and whatever memories she acquires thru the day evaporate once she goes to sleep. Her husband (Colin Firth) leaves a photographic history of their life together on the wall but he must remind her who he is each morning. A doctor (Mark Strong) is helping her in trying to recover her memory. But as the layers are peeled away, she must eventually come to a horrible and violent truth. Based on the award winning, best selling novel by S.J. Watson and adapted for the screen and directed by Rowan Joffe. I'm a sucker for damsel in distress mystery thrillers and for the first two thirds, it's an ingenious "who can you trust" mystery (what might seem as inconsistencies or loopholes are actually clues) until it takes a very dark and disturbing shift in the last third. The film is no more than a clever jazzed up puzzle but with yet another strong performance by Nicole Kidman anchoring the film, it's quite persuasive. With Anne Marie Duff and Adam Levy.
