In the last stages of his career, veteran American director Robert Z. Leonard dabbled in international productions. One of the best-distributed of these was the Gina Lollobrigida vehicle Beautiful But Dangerous. Lollobrigida is cast as Lina Cavaliari, an earthy Italian peasant who becomes a world-renowned opera singer. She also matriculates into something of a mantrap, making up for all the years that she was spurned and ignored by her "betters." One of Lina's many swains is played by none other than Robert Alda. Originally titled La Donna piu bella del mondo, Beautiful But Dangerous benefits immeasurably from Mario Bava's sumptuous cinematography. And as a bonus, La Lollo does her own singing! ~ Hal Erickson, All Movie Guide
