Belle of Old Mexico on AllMovie

After several supporting and guest appearances, Latino singer-actress Estelita Rodriguez was given her own Republic starring vehicle, Belle of Old Mexico. The plot wasn't new in 1950--for that matter it wasn't new in 1920. Wealthy Kip Artmitage III (Robert Rockwell) honors his late wartime friend's request to look after the friend's "little sister." Surprise! Sis turns out to be all-grown-up Rosita (Estelita), causing no end of difficulty for Armitage, who's engaged to marry the avaricious Deborah (Dorothy Patrick). Most of the film's best moments are delivered by Florence Bates as Deborah's eternally inebriated mother. The 70-minute running time affords Estelita Rodriguez plenty of room to perform four peppery musical numbers.
