MARRIAGE ITALIAN STYLE presents director Vittorio De Sica`s fourth collaboration with actress Sophia Loren, and the film exploits the busty Amazon for all she`s worth. In the role of Filomena Marturano, a lusty prostitute, Loren`s costumes range from tiny to scanty. Loren`s fine comic timing, combined with a fine script and the bubbling charm of co-star Marcello Mastroianni elevates the picture from mere titillation to consistently deft and amusing farce. As Domenico Soriano, Mastroianni is on the verge of marrying a younger woman when he hears that his long time mistress, Filomena, is on her deathbed. He rushes to her side, where in a series of flashbacks, the film details the couple`s twenty year relationship. Domenico offers to marry Filomena, but when she recovers miraculously he recognizes that her illness was only a ruse--forcing Filomena to pull deeper from her bag of tricks to catch her man.
