Raoul Peck, who will be at the Cannes Film Festival next month with his George Orwell documentary, “Orwell: 2+2=5,” delivered a blistering warning about the global rise of autocracy this week at documentary festival Visions du Réel, where he is guest of honor.

“Orwell: 2+2=5,” which will debut in Cannes‘ Première section, is made in collaboration with the Orwell estate and delves deep into the British writer’s final months and legacy, including his bestselling novel “1984.”

On Thursday, Cannes chief Thierry Frémaux said at the festival’s press conference that Peck’s film would look at “the strength and relevance of his ideas, and his anticipation of what will become of societies if we don’t take care of them. That was in the ’30s and ’40s. We didn’t pay enough attention to that and maybe we’re not very far from it now; that’s the thesis of this film.
