The directing debut of author Stephen King, it's about an alien phenomenon that causes all the machines in the world to come alive and kill their human masters. It's mostly trucks that kill people. A group of humans make a stand against the machines at a gas station. Emilio Estevez stars as the leader of the group. The premise, based on King's short story Trucks, is a little bit interesting, but it doesn't come off quite well. King had said that he intended to make a junk food movie. Instead, it comes out as rotted garbage. Even King can't seem to make this film, yet another adaptation of his stories, any better. Full of dumb dialogue and even dumber people, Maximum Overdrive is a waste of time and money.
