Here Before review – Andrea Riseborough compelling as grieving mother

A jangling score and unnerving camerawork build tension in story of a woman convinced her daughter is back from the dead

Andrea Riseborough is a powerful actor who could bring emotional complexity to a tomato ketchup advert. Here she's intense in an understated way as a grieving mother who becomes convinced that the girl next door is her daughter, back from the dead. That reincarnation storyline is not unfamiliar, and to be honest it made my heart sink a bit at first. But this atmospheric and unsettling slowburn drama from Northern Ireland pulls it off, just.

Riseborough plays a woman called Laura whose daughter Josie died several years earlier; she lives in Antrim with her husband Brendan (Jonjo O'Neill) and their teenage son Tadhg (Lewis McAskie). They are a family getting on with it, bearing the unbearable. But beneath the dinner table banter, you sense that each of them is alone with their grief. Riseborough signals Laura's loss and longing in every movement; it's there in the way she holds herself stiffly upright, like she might fall apart from heartbreak. When 10-year-old Megan (Niamh Dornan) moves in next door, Laura invites her round for tea and picks her up from school in the car. Megan appears to know things that only Josie would know, recalls places that she can't possibly have seen. Laura starts to believes she is Josie.
