The title of this MGM musical alone should tip you to the fact that Esther Williams is the star. In this one, she plays a movie star (what an innovation!), Rosalind Reynolds, who is on location in Hawaii to shoot a picture. Peter Lawford plays the film's naval technical advisor, Lt. Lawrence Y. Kingslee, who naturally falls deeply in love with Rosalind. As a means of expressing his ardor, Kingslee genteelly kidnaps Rosalind by "accidentally" marooning her on a desert island. To the dismay of feminists everywhere, Rosalind comes to enjoy being Kingslee's prisoner, and all ends happily. Jimmy Durante breaks up da joint in the role of an assistant director, while music is provided by MGM's all-purpose bandleader Xavier Cugat. The Technicolor process is shown to supreme advantage whenever it concentrates on Esther Williams' form-fitting gold-colored swimsuit. On an Island with You was one of MGM's premiere moneymakers of 1948.
