If there was an award for the savviest U.S. distributor at the Cannes Film Festival, it would have to go to Neon, which scored its fourth consecutive Palme d’Or at the conclusion of the 76th edition on Saturday. The top prize went to French director Justine Triet for “Anatomy of a Fall,” a murder mystery and courtroom drama starring Sandra Hüller that Neon acquired shortly after its festival premiere on Tuesday. In the two weeks leading up to the end of this year’s festival, critical consensus focused on “The Zone of Interest,” Jonathan Glazer’s austere riff on Martin Amis’ novel about the commander of Auschwitz.
