“The day when curiosity disappears there’s nothing left but to lie down and wait for our last breath,” said Jacques Rivette. “I believe that curiosity is the one thing which makes us move, which makes us act, in all areas of life.” From February 20 through June 1, London’s Institute of Contemporary Arts is exhaustively showcasing Rivette, one of France’s most influential New Wave cinematic explorers, and where his curiosity took him in the nearly five decades of his career. This landmark retrospective—the U.K.’s first in over 18 years—is a chance to travel down the rabbit hole into Rivette’s mystery-laden filmography. Highlights in the lineup: his most acclaimed film, 1974’s Céline and Julie Go Boating (screening from a 35-mm. print on March 23) and cinema’s 773-minute “holy grail,” Out 1 (March 8 and 9). —Spike Carter
