An Inconvenient Truth (Davis Guggenheim, 2006)
Davis Guggenheim's documentary "An Inconvenient Truth" has the force of a high tide, pulling imperceptibly yet irresistibly upwards until you're knee deep in it, you can't ignore it, and the edge is some twenty feet behind where you're standing at the moment.
The film is a 96-minute documentary on a series of what appear to be Power Point presentations given by Al Gore who, as he puts it "used to be the next president of the United States (when the audience laughs, he replies "I don't find that particularly funny.")." Gore uses animation, graphs and anecdotes to make the not-so-easy-to-grasp case that the world's average temperature is rising, that man's--and especially the United States'--technology has been largely responsible, and that the consequences on our weather and water levels are going to be dire.
I won't mince words on this one--it's one of the most frightening recent movies I've seen. Unlike pictures like "Hostel" or the "Saw" franchise, it portrays ordinary horrors, horrors you are likely to meet every day (step outside in any Metro Manila street and take a deep breath), and are likely to choke on (now try hold that breath).
