Last year, HBO announced that it was adapting Ray Bradbury's Fahrenheit 451 into a movie and today we get its first trailer. In it, we see Captain Beatty, played by Michael Shannon, telling underling fireman Guy Montag (Michael B. Jordan) about the dangers of books and why they have to be burned. "A little knowledge is a dangerous thing," he says. "News, facts, memoirs, internet of old -- burn it." We also see Jordan's character spreading those ideas to school children, lighting room-fulls of books ablaze and saying with barely restrained fury, "I want to burn."
