Rose Glass’s follow-up to her acclaimed Saint Maud is a scorchingly sexy, darkly violent tale of a gym manager’s love affair with a bodybuilder

This may seem an unexpected point to make about an actor who is arguably one of the coolest people on the planet, but the key to Kristen Stewart’s mesmerising screen presence is her ordinariness. I don’t mean her looks, although as Lou, the manager of a bodybuilding gym in an insalubrious New Mexico backwater, Stewart’s natural magnetism is somewhat muted behind a whey powder pallor, an air of defeated weariness and hair that looks as if it’s been deep-fried rather than washed.

Rather, it’s the unstudied, naturalistic quality of her performances, which are seeded with little glitchy details and gestures – the way she rakes her fingers through her fringe; the moment when she nervously wipes her nose on the sleeve of her T-shirt.
