The 1951 sci-fi classic gets a remake with Keanu Reeves as the alien Klaatu, who is prepared to have his robot enforcer, Gort, destroy the earth in order to prevent a global crisis caused by humans not changing their wasteful, violent ways. As Fox’s first green production, the eco-initiative mandated reducing paper waste; using recyclable and biodegradable materials and sustainably produced lumber in sets and props; and conserving energy via hybrid vehicles, bio-diesel generators and efficient appliances on set.
