The Duke is the main antagonist of the 1981 John Carpenter movie Escape from New York. He is portrayed by the late Isaac Hayes.
He holds the President of the United States hostage after his plane is hijacked by terrorists and it crashes in New York. Snake is soon captured by the Duke and is forced to do battle in a massive arena. Snake defeats his opponent and Snake and his allies attempt to escape the mine-filled 69th Street Bridge, with the Duke in pursuit. Most of Snake's friends are killed in the process, and when the Duke attempts to kill Snake, the Duke is finally killed when the President shoots him to death.
