Cate Blanchett, Roy Dupuis, Nikki Amuka-Bird, Charles Dance, Takehiro Hira, Denis Ménochet, Rolando Ravello, Zlatko Burić and Alicia Vikander. But if one had to say more, one could add that it’s a comedy that imagines a meeting of the G7 leaders, who have to deal with an unspecified global crisis (left to our imagination), and find themselves surrounded by figures straight out of a horror movie. A satire with brain — in more ways than one.
