This stunning 2002 video by Canadian conceptual artist Michael Snow might be his greatest work since La region centrale. His most accessible feature, it combines elements from virtually all his previous films, including inexorable camera movements, encyclopedic cataloging, and playful self-reflexivity. His first encounter with digital video, it explores all the things DV can do to stretch, compress, and distort bodies, a subject he explores formally, comically, and at times even ideologically. (There’s a lot of dialectical play between two distinct spaces: a contemporary row of staffed computer stations, backed by windows overlooking a cityscape, and a sealed-off bomb shelter of a living room, filled with 50s kitsch and inhabited by an all-American family, in which the TV set clearly “rhymes” with the computer screens.) Not counting the asterisk, the title refers to the tissue connecting the hemispheres of the brain, an apt reference given the prodigious and joyful inventiveness on display. 93 min.
