Director Scott Derrickson’s remake of the 1951 sci-fi classic replaces the original’s theme of fear of impending nuclear war with current concerns about environmental catastrophe. Keanu Reeves stars as Klaatu, an alien sent by a confederation of extraterrestrial beings to warn the inhabitants of Earth that the biosphere is on the verge of collapse. Predictably, as soon as he emerges from his spaceship a trigger-happy soldier ignores his instructions and takes a shot at the visitor. The wounded Klaatu asks for access to the United Nations to deliver his message, but the Secretary of Defense, Regina Jackson (Kathy Bates), instead orders that he should be taken away for further investigations. And so Klaatu becomes increasingly convinced that Earth can only survive if mankind is eradicated… Also starring Jennifer Connelly, Jaden Smith and John Cleese.
