The Taking of Pelham One Two Three

Walter Matthau stars as a New York transit cop who must keep four ruthless terrorists who've hijacked a Bronx subway car from killing hostages (a pimp, a pregnant Puerto Rican woman, a hippie, a prostitute, a WASP, a wino, and a gay man) one by one if their $1,000,000 ransom demand is not met within an hour.
