Ah, I figured re: Oh Mercy/Roubaix, une lumière. A film in two halves, both of which I really liked: the first is a moody environmental* noir centered on Roschdy Zem as this weathered, determined, kind but tough cop trying to make it work France's toughest city, and the second one is basically a series of interrogation scenes trying to untangle a specific crime that occured, with Léa Seydoux and Sara Forestier as the main suspects (and Zem doing the interviewing of course). Zem and Seydoux are great (though it's Forestier who got a nom at the César, and she's good too), and Desplechin adds a lyricism to the first half in particular which made the film really work on another level for me.
Sad that Bacurau isn't a contender for Foreign Film, I guess it hasn't been released in the US yet ? I certainly did not expect Mendonça Filho to go for a Carpenter vibe after Aquarius, but he sure did, and it work so well.
Motherless Brooklyn I'm alone in loving I know, but at least people might recognize the greatness of its impeecable cool jazz score... I guess not.
*not in the "saving the planet" way, more the "this is an environment/milieu, let's discover it"
