Seemingly from out of nowhere, actor turned director Gilles Lellouche throws a Molotov Flanby into the Competition with only his second feature, a terrific and unexpectedly potent piece of genre filmmaking that could, to avoid spoilers, be described as a kind of mash-up of Badlands and La Haine, as if directed by Walter Hill. Throw in a little Eurocrime, from the likes of Fernando Di Leo and late-period Jean-Pierre Melville, and you’re getting close to what Lellouche has achieved here, a romantic banlieue opera that delivers all the gritty, vicarious thrills of the now-standard post-Goodfellas gangster movie but also burrows into issues of class and gender in refreshingly unpredictable ways.
