I don't know the song. All I can say is, we're fucked. I read on the back of my DVD that David Ansen of Newsweek calls the film "a gripping thriller." So buy it already, everyone. But the director's documentary reveals that his film isn't a thriller at all, and it probably can't even be considered a warning. It's just his way of saying we're fucked. Truly. If you haven't watched it, please do. It's worth the price of another rental, I assure you, despite being a mere half hour or so long. It predicts global warming resulting in mass migrations of desperate people and tribal societies ruled by ruthless warlords this century... And there's nothing anyone can do to stop it... Except plan to somehow survive. I have two kids. Fuck. Fuck.
