There has been a rich harvest of taut thrillers in 2014, including Blue Ruin and Cold In July and gritty British films Locke and Starred Up.

With David Fincher’s adaptation of Gone Girl looming on the horizon, this is undoubtedly a year when audiences will catch themselves returning to filthy habits and furiously biting their nails in the dark of an unbearably tense cinema.

Before I Go To Sleep is guaranteed to jangle nerves and drop a few jaws as summer mellows into autumn.

Based on SJ Watson’s bestselling novel, this ingenious thriller places us in exactly the same hellish predicament as the heroine, who wakes up each morning without any memory of the past, including her own identity.

Through the eyes of this terrified wife, we absorb scraps of information from supposedly reliable sources and try to piece together the truth, unsure if writer-director Rowan Joffe is leading us a merry, sadistic dance.

The guessing game of who to trust is part of the film’s diabolical appeal and the script engineers some wonderful bluffs until a gasp-inducing big reveal that should have audiences teetering precariously on the edge of their seats.
