Doug Pray is shaping up to be the finest documentary filmmaker out there as soon as Errol Morris retires. Pray is a crackerjack editor (he cut the Hughes Brothers' great American Pimp) and a man who approaches his own documentaries as polished learning experiences that manage to both cram in copious information and stay fascinating throughout. His previous films, Hype, Surfwise, and especially Scratch are all essential.
At Sundance, Pray recently screened his new one, Art & Copy, which delves into the seedy world of dark magic that is advertising. The AV Club didn't care for it so much, but I still think I have to see this one.
