We’re all used to seeing drug lords, aliens, and would-be world rulers as the evil villains in movies. But how about ordinary citizens despoiling the environment? Well that’s the hot new theme for Hollywood, according to the International Herald Tribune, which reports that a stream of high-budget eco-thrillers will soon be hitting the big screen. In one called “Avatar,” humans have exhausted the resources of the earth, and have to resort to raiding other planets, where the inhabitants fight back. “The Happening” is another big-budget film with an environmental twist, and even lovable Homer Simpson may be getting in on the action, as eco-doom is rumored to be a plot line for The Simpson’s upcoming Hollywood debut.
