Tilda Swinton in Memoria, Kenneth Branagh’s memorial to Belfast and Edgar Wright’s 60s horror: the Guardian’s chief film critic chooses his must-sees at this year’s festival
Céline Sciamma’s beautiful fairytale reverie is mysterious and moving. After her grandmother’s death, an eight-year-old girl comes with her troubled mum to clear out the old woman’s house and in surrounding woodland she meets another eight-year-old, just like her – a ghost or vision of her mum in her childhood. The two girls are played by twins.
