Film forty-eight of the festival and Bertrand Mandico's Roma Elastica is a kaleidoscope of Fellini riffs, carnival grotesques, feminist cannibal peplums, and one extraordinary scene in which Marion Cotillard turns before a mirror and briefly makes everything feel necessary. We talk about what Mandico does that nobody else does, why it works in flashes and exhausts in bulk, and why Cotillard is incapable of giving a bad performance even inside a deliberately incoherent film.
