Matrimonio All'Italiana (aka Marriage Italian Style) (1964)

A self centered but successful businessman (Marcello Mastroianni) meets a young prostitute (Sophia Loren) in a brothel during WWII. He takes her as his mistress but never marries her and she is treated more or less like an employee or servant. But after 22 years, when he decides to marry a young girl (Marilu Tolo), she takes matters into her own hands to get what's rightfully due her. Based on the play FILUMENA MARTURANO by Eduardo De Filippo and directed by Vittorio De Sica. This warm and human comedy is a great showpiece for Sophia Loren, who almost always did her best work for De Sica. Loren goes from age 17 to her 40s and her physical changes are remarkable. It's not just aging make up but her body grows and moves appropriately for the ages she's playing. Of course, the chemistry between her and Mastroianni is pure magic (they did 13 films together). The lovely score is by Armando Trovajoli. With Aldo Puglisi, Tecla Scarano, Gianni Ridolfi, Generoso Cortini and Vito Moricone.
