The sheer unsparing intimacy of Gyllenhaall’s film gives its thrills an excitingly illicit quality. Watching it feels like reading someone else’s diary – and then finding yourself mentioned in its pages.

The Lost Daughter leaves you haunted, shaken, and crushingly scarred like only the best of films are capable of doing.

Gyllenhaal’s film is a story of self-ascribed transgression and of shame buried and turned bitterly inward, and it too, is made with such alertness to the power of cinematic language – particularly that of performance – that even as you feel your stomach slowly drop at the implications of what you’re watching, you cannot break its spreading sinister spell.

The reclusive Italian author’s familiar themes of female relationships, sexuality, motherhood and women’s struggle to carve a professional space outside it are beautifully served in this uncompromising character study, illuminated by performances of jagged brilliance from Olivia Colman and Jessie Buckley as her younger self.

Ultimately what makes this an unusually rewarding picture about motherhood is the fact that it shatters the binary distinction between the good mother and the bad one.
