Basil Gelpke and Ray McCormack’s nonfiction treatise Crude Awakening joins Maxed Out, An Inconvenient Truth, and other recent documentaries devoted to unearthing and exploring forces that are untying the connective threads of contemporary society. The subject at hand is crude oil - specifically, the depletion of petroleum from the Earth, in an era when consumption threatens to exceed supply.

The overtone of the film is speculative but admonitory; Gelpke and McCormack suggest that if western society fails to reinvent itself altogether (via such innovations as hydrogen-powered autos, and a decreased reliance on fiscally unsound Middle Eastern nations), economic cataclysm is not simply likely but inevitable.

To underscore this point, the filmmakers contrast obscenely naïve shorts from the 1950s that promise depthless oil supplies, with contemporary warnings from geologists who suggest that the bottom of the well is close at hand. McCormack and Gelpke| also interview such subjects as former OPEC secretary general Fadhil Chalabi and Bush advisor Roger E. Ebel. (Barnes & Noble)

While the previous eco-doc Who Killed the Electric Car? spent some time on the world’s oil crisis, A Crude Awakening (formerly OilCrash) builds an entire film around the subject. Swiss journalist Basil Gelpke and Irish filmmaker Ray McCormack have constructed their narrative in a conventional manner, alternating between talking heads, archival footage, and modern-day material, but the addition of several pieces by Phillip Glass is an artful touch (and evokes his work on 1988’s The Thin Blue Line).

Throughout, a diverse array of experts from the U.S., Azerbaijan, Venezuela, and other countries explain how the 20th century became addicted to “the blood of the dinosaurs,” and why contemporary society needs to change course. As attorney/activist Matthew David Savinar puts it, “Oil is our God.” As Stanford professor Terry Lynn Karl adds, “More and more oil is going to come from less and less stable places…places that actually challenge the taking of oil in the first place.”

One of the more chilling revelations concerns the discrepancy between the reserves oil-producing nations claim they possess and the actual amount. These padded estimates allow them to drill with impunity, leading to an abundance of wealth in the short term and cataclysmic consequences once they’ve depleted their supply of this non-renewable resource.

A Crude Awakening isn’t exactly a day-brightener, but Gelpke and McCormack are comprehensive and impartial in their inquiry, which makes for an informative examination of a vitally important subject. Extras include extended interviews with four participants and bonus chapter. (Amazon)
