Colin Firth wakes up from a coma to discover that his wife (Naomie Harris) has been killed in a car crash while he was at the wheel. Unable to make sense of his grief, his sanity unravels. So does reality. Kenneth Cranham’s detective suspects him of murdering a pop star. Mena Suvari’s sympathetic neighbour takes him to a medium who tells him his wife is still alive. Firth retreats into spooky isolation.
It’s not wilfully tedious — Firth is grimly watchable as the manic hero — but it doesn’t trip off the screen.
