While the obsession is overdone (William, especially, is drenched in it like cloying duty-free aftershave), the sex itself, including what appears to be a beginner’s guide to bondage and submission, seems stilted. Clearly, intimacy coordinators are working overtime, but that’s not the problem. Anna and William are mainly about the sex scenes, which seem to arrive in Bogof batches. It’s left to Indira Varma, as William’s wife, Ingrid, to burn up the screen with emotion. Obsession is beautifully shot, and via Morgan Lloyd Malcolm and Benji Walters’s script you occasionally get some sense of Anna’s inner life, her motivations, though not nearly enough. Rarely has a tempestuous affair been made to look like such a chore. Elsewhere, they sombrely copulate in toilets mechanically rut in alleyways. Before long they’re naked, clamped together like erotic Lego, on the fabulous polished floor of a borrowed flat. An olive is eaten in a provocative manner. When William and Anna meet, mutual smouldering ensues. Richard Armitage ( The Stranger) plays William, a married, designer-stubbled surgeon going into politics, while Charlie Murphy ( Happy Valley) is Anna, the enigmatic new squeeze of William’s son Jay (Rish Shah).
