Franz Rogowski plays self-obsessed film director Tomas, married to artist Martin (Ben Whishaw), but forever curious for more.
That more arrives in the shape of Agathe (Adèle Exarchopoulos), a teacher he meets at a bar before finding himself in her bedroom. He’s brazenly proud when recounting the tale back at home but when lust turns to love, or at least his concept of it, whatever conflicted openness Martin might have previously had soon curdles into distaste.
Its sophisticated approach to romance (or, perhaps, the absence of it) is not too cool or alienating, because Sachs and his sterling cast give the film such textured, specific life. N.B. This is an 18-certificate film containing graphic sex scenes.
