Stéphanie (Cotillard) is a hard-living trainer of killer whales at
the local Marineland. (If that seems baroquely, uniquely French, it’s
worth noting that the screenplay by Audiard and Thomas Bidegain is based
on a short story collection by Canadian writer Craig Davidson.) She and
Ali meet at the club; he drives her home and casually puts her pompous
boyfriend in his place. There’s an accident at the water park, filmed by
cinematographer Stéphane Fontaine with jagged beauty, after which
Stéphanie wakes in the hospital to find her legs bitten off. Cotillard’s
performance in that scene alone is worth the price of admission: She
makes what could be a bizarre joke seem terrible and present.
“Rust and Bone” is thus about two castoffs who comfort each other
without realizing how tightly they cling. Reconnecting, Ali takes
Stéphanie swimming in the ocean, and the look on Cotillard’s face as her
character realizes she won’t be denied her single greatest pleasure is
something to see.
