Truman's world is controlled by a TV producer named Christof (Ed Harris), whose control room is high in the artificial dome that provides the sky and horizon of Seahaven. He discusses his programming on talk shows, and dismisses the protests of those (including Sylvia) who believe Truman is the victim of a cruel deception. Meanwhile, the whole world watches Truman's every move, and some viewers even leave the TV on all night, as he sleeps.
