Marriage Italian Style (1964)

Domenico, a successful businessman, with an eye for the girls, begins an affair with Filumena when she is 17 years old. She becomes a prostitute, but also becomes the mistress of Domenico. He eventually sets her up in an apartment, and she works for him in his various businesses. She secretly bears three children, who are raised by nannies. Domenico starts planning to marry a young employee. Filumena tricks him into marriage by pretending to be dying. Domenico annuls the marriage. Filumena then tells him of the three children. She says that one of the children belongs to Domenico, but will not say which one is his. You start to believe that all of the children could be his, and Domenico then marries Filumena again, this time willingly.—Steve Jordan
