The Dolly Sisters is the heavily Hollywoodized biopic of Jennie and Rosie Dolly, Hungarian-born entertainers who took Broadway by storm in the early 1900s. Betty Grable plays Jennie and June Haver plays Rosie; their uncle is the inevitable "funny foreigner" S.Z. Sakall, who manages their career from childhood. Passing an important audition for Oscar Hammerstein, the Dolly girls become international stage headliners, but in so doing they find that their private life is strained. Jennie in particular is perplexed by the dilemma of devoting herself to a career while still finding time to romance handsome composer John Payne. The Dolly girls are separated permanently when Rosie is fatally injured in an auto accident, but Jennie finds lasting happiness with her composer. Despite the pre-World War I ambience of the film, both Grable and Haver show off a lot more skin than would have been permissible in earlier times. But Dolly Sisters producer George Jessel knew what he was doing, and the Technicolor film was a major hit in 1945.
