The four men on this year's Palme jury are Canadian director Denis Villeneuve (Blade Runner 2049); Russian director Andrei Zvyagintsev (whose lost-child drama Loveless competed for the Palme last year, winning the Jury Prize); Chinese actor Chang Chen (Crouching Tiger, Hidden Dragon); and French writer/director Robert Guédiguian (The Snows of Kilimanjaro).
DuVernay, the filmmaker of "Selma" and the Netflix documentary "13th", said that the power of movies is the ability to "speak to each other through cinema".
