William Berkeley Enos was born in 1895 in Los Angeles, California. He choreographed several Broadway revues before moving to Hollywood in 1930. It was there, from 1933-39, at Warner Bros. that he achieved his greatest successes. Berkeley became famous for staging elaborate dance numbers in which lines of showgirls performed synchronized movements which, photographed from innovative angles, particularly from above, created kaleidoscopic, often surreal patterns of moving figures. The height of his style was reached in the 1930s in such films as 42nd Street (1933), Dames (1934), and a series of Gold Diggers movies, for which he directed either the dance sequences or the entire production. He went on to direct many other beloved movies such as collaborations between Mickey Rooney and Judy Garland, Gene Kelly and Frank Sinatra, and even the water ballets of Esther Williams. Berkeley's career extended 1970, at which time he directed a Broadway revival of No, No Nanette.
