A pair of mesmerizing nonfiction films derive visual poetry from the relationship between the group and the individual. Filmed near the Shaolin Temple in Henan, China, Iyabo Kwayana’s short PRACTICE transforms a portrait of students engaged in martial arts training into an immersive, dazzlingly kinetic meditation on collective movement, ritual, and athleticism. It’s a perfect warm-up for one of the signature achievements by essay-film pioneer Chris Marker, the captivating travelogue SANS SOLEIL, in which a kaleidoscope of images are arranged and pondered by a narrator as mysterious as the places on his itinerary.
