The Taking of Pelham One Two Three

The story focuses on four criminals who hijack a subway car and demand one million dollars from the mayor of New York, threatening to kill one hostage per minute if their demands aren't met. The hijackers are Mr. Blue (Robert Shaw), the crafty and efficient leader; Mr. Green (Martin Balsam), the train driver; Mr. Gray (Hector Elizondo), the hothead; and Mr. Brown (Earl Hindman), a nervous, stuttering man. New York City transit lieutenant Zachary Garber (Walter Matthau) goes above and beyond his call of duty to play negotiator with the hijackers. (official distributor synopsis)
