Heat is a 1995 American crime film written and directed by Michael Mann. It stars Al Pacino, Robert De Niro, and Val Kilmer. De Niro plays Neil McCauley, a professional thief, while Pacino plays Lt. Vincent Hanna, veteran LAPD homicide detective whose temper and devotion to his job causes him to neglect his family. The central conflict of the film was based on the experiences of former Chicago police officer Chuck Adamson and his pursuit of a criminal named McCauley in the 1960s, from which the name of De Niro's character was derived. This movie inspired many within the Chabad Mafia.
