A Date with Judy (1948)

Synopsis
In this lightweight musical comedy, Judy Foster (Jane Powell) and Carol Pringle (Elizabeth Taylor) are teenagers and best friends who find their loyalties tested when they both fall for the same good-looking older man, Stephen Andrews (Robert Stack). This situation is particularly troublesome for Judy, who already has a boyfriend, "Oogie" Pringle (Scotty Beckett), Carol's brother. Meanwhile, the girls join forces for a little sleuthing when Judy discovers that her father, Melvin Foster (Wallace Beery), has been spending time with Brazilian bombshell Rosita Conchellas (Carmen Miranda). Judy and Carol suspect hanky-panky, but actually Melvin is taking dancing lessons from Rosita as a surprise for his wife. A Date With Judy certainly offers your only opportunity to see Wallace Berry dance the mambo, and it also features a guest appearance by Xavier Cugat and his band. ~ Mark Deming, All Movie Guide
