Here Come The Waves (1944)

Set during WWII, two identical twin sisters perform as a singing act in nightclubs. The blonde sister (Betty Hutton) is impractical and scatterbrained while the brunette sister (Betty Hutton) is down to earth and reliable. Feeling patriotic, they join the WAVES where they encounter a famous crooner (Bing Crosby) that the blonde sister has a crush on. Directed by Mark Sandrich (TOP HAT). This silly wartime musical is on the trite side but it has two things going for it. The first is a terrific song by Johnny Mercer and Harold Arlen, Ac-Cent-Tchu-Ate The Positive which was nominated for a best song Oscar and became a standard. Alas, it's performed in blackface (by Crosby and Sonny Tufts) which makes watching it performed uncomfortable. The second is Betty Hutton's performance as the twin sisters. As the blonde, she's the usual frantic and loud Betty Hutton but as the brunette, she's subdued and restrained. Clearly, she could act outside that frenetic persona that turns a lot of people off but that's the Hutton the public wanted to see. The film was a big hit at the box office. With Ann Doran, Catherine Craig and Noel Neill, who would find some fame in the 1950s on TV as Lois Lane on the SUPERMAN TV series.
