Film eighteen of the festival and Karma, Guillaume Canet's cult melodrama starring his now-ex-wife Marion Cotillard, is exactly as juicy as it sounds. Flawed, lurid, two and a half hours long, and Cotillard carries every single minute of it. We talk about what the film gets right, what it strains to sell, and why Denis Ménochet might be the most quietly terrifying presence at this year's festival.
