Yesterday, Today and Tomorrow (originally known as the Italian Leri, Oggi, Domani) is a 1963 comedy starring Sophia Loren and Marcello Mastroianni. It’s somewhat unique in that the film is comprised of three short stories, each with couples from different parts of Italy. In each case the couple is played by Loren and Mastroanni.
In the first tale Loren is a woman who stays out of jail for her troubles by constantly remaining pregnant through the help of Mastroanni (who would refuse?). In the second they play a pair of lovers who meet in secret and who must work out all their problems in a car. And, in the third, Loren plays a hooker looking to help a neighbor get back to their seminary. Mastroanni plays one of her johns who she enlists to help.
The film managed to do quite well, winning an Academy Award, a BAFTA and a Golden Globe.
