Before I Go to Sleep - Film4

Star Nicole Kidman gets a shock

A neatly done thriller. 3/5 stars

Nicole Kidman wakes each morning with no memory of the last 14 years, leaving loving husband Colin Firth to patiently explain who he is every day.

Mark Strong is a neurosurgeon whose surreptitious gift of a camera helps her to slowly piece her past together. But the more she discovers, the more scared she becomes - and who can she really trust..?

Kidman's disorienting plight is both affecting and chilling, but the plot's supposedly cunning twists are a little too predictable for the film to grip as tightly as it should.

Jason Best

A film critic for over 25 years, Jason admits the job can occasionally be glamorous – sitting on a film festival jury in Portugal; hanging out with Baz Luhrmann at the Chateau Marmont; chatting with Sigourney Weaver about The Archers – but he mostly spends his time in darkened rooms watching films. He’s also written theatre and opera reviews, two guide books on Rome, and competed in a race for Yachting World, whose great wheeze it was to send a seasick film critic to write about his time on the ocean waves. But Jason is happiest on dry land with a classic screwball comedy or Hitchcock thriller.
