Remarkably, three full-length documentaries are in circulation about the perils and benefits of the new shale drilling boom in the US. The first, Gasland, relates stories of the horrors caused by drilling in locations across the country. It won an award at the 2010 Sundance Film Festival, and is now showing on HBO. Its official website is a call for environmental action. The second documentary, Haynesville: A Nation’s Hunt for Energy, has been shown at several film festivals and can be seen in Dallas, Houston and Forth Worth in July. The film critic for the Fort Worth Star Telegram calls Haynesville “fairer and smarter” than Gasland. Watch the trailer at its website. The newest film is Gas Odyssey, which advocates development of the Marcellus shale in New York State. Its maker Aaron Price says that the issue of hydraulic fracturing “stopped being about science and facts a long time ago It has become a political monster, and my hope is that this film will transcend politics and restore basic rights to New Yorkers – to develop their land through a tried and true, safe technology.” Watch all three and make your own conclusions.
