Spike Lee's incendiary look at race relations in America, circa 1989, is so colourful and exuberant for its first three-quarters that you can almost forget the terrible confrontation that the movie inexorably builds toward. Do the Right Thing is a joyful, tumultuous masterpiece--maybe the best film ever made about race in America, revealing racial prejudices and stereotypes in all their guises and demonstrating how a deadly riot can erupt out of a series of small misunderstandings. Set on one block in Bedford-Stuyvesant on the hottest day of the summer, the movie shows the whole spectrum of life in this neighbourhood and then leaves it up to us to decide if, in the end, anybody actually does the "right thing." Featuring Danny Aiello as Sal, the pizza parlour owner; Lee himself as Mookie, the lazy pizza-delivery guy; John Turturro and Richard Edson as Sal's sons; Lee's sister Joie as Mookie's sister Jade; Rosie Perez as Mookie's girlfriend Tina; Ossie Davis and Ruby Dee as the block elders, Da Mayor and Mother Sister; Giancarlo Esposito as Mookie's hot-headed friend Buggin' Out; Bill Nunn as the boom-box toting Radio Raheem; and Samuel L Jackson as DJ Mister Señor Love Daddy. This is a rich and nuanced film to watch, treasure and learn from--over and over again. --Jim Emerson
