La Jetée and Sans Soleil couldn't seem more different—but they're the twin pillars of an unparalleled and uncompromising career in cinema. La Jetée (1962), a tale of time travel told almost entirely in still images, is one of the most influential and radical science-fiction films ever made. Sans Soleil (1983), a free-form meditation on time, memory, and Japan and Africa as seen through the eye of an omnivorous camera, is equally challenging and rewarding. A filmmaker, poet, novelist, photographer, editor, Chris Marker has been challenging moviegoers and philosophers for years with his investigations of time, memory, and the rapid advancement of life on this planet.
