The most important, scary, and inspirational documentary you are likely to see this year is An Inconvenient Truth. Essentially an expanded version of a presentation that former-Vice President Al Gore has been giving since the late 1980s on the visible perils of global warming, the film also incorporates archival footage of the-man-who-should-be-President's political life gathering support and enlightening citizens around the world on what should be a non-partisan issue. It's not a lecture, but that doesn't stop it from being a must-see eye-opener. The film opens today at the Landmark Century Center Cinema, the AMC River East theatre and at the Evanston Century theatre. (Thanks, Steve)
