Modern update of 'The Wizard of Oz' with Diana Ross as Dorothy leading her gang of no-gooders to the disco chic city of New York. Plenty of Motown music and dance routines are provided by an all black cast.

Arthur Bach (Dudley Moore) is a millionaire playboy who spends most of his life drunk, mollycoddled by cynical manservant Hobson (John Gielgud). Threatened with poverty by his grandmother unless he finally marries his socialite fiancée Susan (Jill Eikenberry), Arthur's response is to embark on an affair with penniless, working class waitress Linda (Liza Minnelli). John Gielgud won an Oscar for Best Supporting Oscar, and a sequel, 'Arthur 2', followed in 1988.
