Plastic makes it possible: Indeed, "every three seconds another house in North America is sided with vinyl," reads the opening title to Judith Helfand's HBO documentary Blue Vinyl. Tacky, yes, and sinister. After Helfand's had her 100 minutes with you – visiting PVC-making plants and the diseased neighbors who live near them, consorting with legal muckrakers who've exposed manufacturers' schemes to keep the public uninformed about PVC's dangers to the environment, and getting intimate with former PVC workers dead or dying from exposure to toxic goo – those words are below-zero chilling. At Sundance this past year, Helfand, the Michael Moore of the moment, supplemented the frightening take-home message with cheerful handmade tchotchkes – the actual vinyl from her parents' Long Island home, now being recycled as the pendants on Mardi Gras-beaded necklaces. Lately, Helfand's turned the revelations into a road show, which hit town earlier this week at the Oakland Museum – as a collaborative effort with Bay Area Cancer Coalition, the Center for Environmental Health, Greenaction, Healthcare without Harm, and the Healthy Building Network – and continues with community-based screenings throughout the month. The Bay Area comes across in the film as a utopian paradise of recycling, featuring local homes made with recycled license plates and experts in straw-bale home manufacture, but these screenings, organized with the help of Blue Vinyl coproducer and Bay Area resident Julia D. Parker, are targeting populations affected by toxic processing in their neighborhoods, as well as green builders and their friends. Look out for Blue Vinyl at a May 6 screening at the Shields Reid Community Center, near north Richmond's oil refineries; a May 9 screening at the Natural Step Sustainability Conference, at Cowell Theater in Fort Mason Center; a May 15 screening and panel discussion with architects, designers, and members of Planners for Social Responsibility and Healthy Building Network, at the Pacific Energy Center in downtown San Francisco; and other to-be-determined events at the end of May and in early June in Hunters Point, west Oakland, and Redwood City.
