The critics and public agree. Brian de Palma's The Untouchables is a must-see masterpiece glorious, fierce, larger-than-life depiction of the mob warlord who ruled Prohibition-era Chicago and the law enforcer who vowed to bring him down. This classic confrontation between good and evil and stars Kevin Costner as federal agent Eliot Ness, Robert de Niro as gangland kingpin Al Capone and Sean Connery as Malone, the cop who teaches Ness how to beat the mob: shoot fast and shoot first.
