Crossroads is a 1976 short film directed by Bruce Conner. It features 37 minutes of extreme slow-motion replays of the July 25, 1946 Operation Crossroads Baker underwater nuclear test at Bikini Atoll in the Pacific. The event was captured for research purposes by five hundred cameras stationed on unmanned planes, high-altitude aircraft, boats near the blast, and from more distant points on land around the Atoll. The location was selected in part because the network of islands formed an almost complete ellipse around the detonation site, allowing for a comprehensive documentation of the event from numerous angles. The music is by Patrick Gleeson and Terry Riley.
