Heat (1995)

Michael Mann's Heat features the only film scene in which Al Pacino and Robert De Niro — each among cinema's greatest living actors — appear on screen together for the first time. The film's 12-minute downtown Los Angeles bank robbery, choreographed with SAS personnel to achieve unprecedented tactical realism, became a training standard for actual LAPD tactical units and has been studied at police academies internationally. The film's exploration of obsessive professionalism on both sides of the law became the defining template for the heist thriller genre.
