Walton, however, has been one of the preeminent stage designers since the 1960s. Beginning with his witty costumes and sets for "A Funny Thing Happened on the Way to the Forum" in 1963, he has created the look for many successful musical productions including the Fosse-directed "Pippin" (1972) with its Carolingian setting, and "Chicago" (1975), set in the 20s, the Tommy Tune-staged "A Day in Hollywood/A Night in the Ukraine" (1980), which recreated the Tinseltown glamour in of the 30s, and "Grand Hotel" (1989), set in pre-war Berlin, and the acclaimed revival of "Guys and Dolls" (1992). Walton has frequently worked with Mike Nichols, creating everything from the barracks of "Streamers" (1977) to the contemporary English settings of Tom Stoppard's "The Real Thing" (1984). More recently, Walton has branched out into directing, staging and designing a well-received 1996 revival of Oscar Wilde's "The Importance of Being Earnest".
