The new poster for Nicole Kidman's compelling psychological drama Before I Go To Sleep was released on Friday - and it doesn't answer any of the questions posed by the trailer.
Based on the 2011 best-selling novel by S.J. Watson, Before I Go To Sleep also stars Colin Firth and Mark Strong.
Nicole plays a woman who due to a traumatic accident in her past wakes up every day remembering nothing.

She lives with husband (Colin), and her doctor (Mark) calls every day to remind her who she is, until one day new and horrifying truths force her to question exactly what is happening to her and why.
Also starring Anne-Marie Duff, the film has been described as an edge-of-your-seat thriller, and the trailer delivers a creepy, twisty tale where, just like Nicole's heroine, we don't know who to trust.
Oscar winner Nicole has always been very open about how important her family is to her, and she recently told Australian magazine Women's Weekly how proud she is of the people her two adopted children with ex-husband Tom Cruise have become.

"They are generous, kind and hardworking, and these are traits that I love to see in my children", she told the magazine before adding that if she had to choose between her career and her loved ones, there would be no contest.
"If it were a choice between my family and Keith, and my career, I wouldn't even bat an eyelid," she said. "The most important things to me are the love of our relationship and my children.
"At this stage of my life, and with time being so precious, the joy I get from us as a family far outweighs any joy in any other area in my life, by far."
At the Cannes Film Festival in May, Nicole found herself defending Grace of Monaco, which premiered as the opening film.

The movie has been dismissed by Grace Kelly’s son Prince Albert of Monaco and his sisters Princess Stephanie and Princess Caroline as "needlessly glamourised" and "historically inaccurate".
"I get why the children are upset," Nicole said at a press conference. "I have great respect and regard for their mother. It's not meant to be a biopic.
"I certainly did my best to honour everything that was real and truthful in it."
Before I Go To Sleep is out in the UK on 5 September.
