Director Scott Derrickson's remake of the 1951 sci-fi classic replaces the original's theme of fear of impending nuclear war with contemporary 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 Defence, Regina Jackson (Kathy Bates), instead orders that he should be taken away for further investigations.
Aided by friendly scientist Dr Helen Benson (Jennifer Connelly), it's not long before Klaatu is able to escape the US government's clutches. But by this time Klaatu has concluded that Earth can only survive if mankind is eradicated...
Also starring Jaden Smith and John Cleese.
