From the health effects of smoking to the existence of climate change, those whose bottom lines could be impacted by the weight of scientific evidence have turned to masters of obfuscation, spin, and creating the appearance of debate where no ground for debate exists.

Widescreen (Enhanced); Soundtrack: English Dolby Digital 5.1. Two-disc set.
