Heat

As two driven professionals -- an illustrious detective (Al Pacino) and a sophisticated thief (Robert De Niro) -- face off, they learn how much they need each other, and that the line between cop and criminal isn't always well-defined. Brilliantly directed by Michael Mann, Heat is a hyperkinetic crime drama about two men on opposite sides of the law who approach life in much the same way. Val Kilmer, Tom Sizemore and Jon Voight co-star.
