Cuban Fireball is a vehicle for the combustible talents of Estelita Rodriguez, here cast as "herself." The plot finds Estelita arriving in Los Angeles to claim a multimillion-dollar inheritance. To fend off fortune hunters, she disguises herself as a meek little old lady. The rest of the story sustains this level of credibility. Warren Douglas co-stars as Estelita's true love, while Leon Belasco is the most prominent of the film's many antagonists. The film's 78-minute running time affords ample opportunity for Estelita Rodriguez to render four songs. Dyed-in-the-wool fans of Republic Pictures will easily recognize Cuban Fireball as a South-of-the-Border retooling of the studio's popular Judy Canova musical comedies. ~ Hal Erickson, Rovi
