Oil giant Chevron wants documentary filmmaker Joe Berlinger to turn over hundreds of hours of raw footage he shot for his documentary film on pollution in the Amazon rainforest. Chevron's lawyers say they want the material because it may be helpful in lawsuits that accuse the company of damaging the environment in Ecuador. Berlinger's past films include Paradise Lost and Metallica: Some Kind of Monster. He says he was recently served with a request from Chevron for more than 600 hours of unused footage for his 2009 documentary Crude, which you can purchase here on DVD. Trailer here.
