THE Hurricane Katrina chronicle "Trouble the Water," winner of this year's Sundance Grand Jury documentary prize, has been picked up for US distribution by Zeitgeist Films. Tia Lessin and Carl Deal's "Water" uses camcorder footage that aspiring rapper Kimberly Roberts and Scott Roberts shot before and during the New Orleans disaster. The film tracks the couple through the aftermath, taking a critical look at the government's response and media coverage. The film will receive an Oscar-qualifying run in Los Angeles and New York beginning August 22, followed by a gradual national rollout.
