YESTERDAY, TODAY AND TOMMORROW (1963)

IERI, OGGI, DOMANI (1963)  

Directed by Vittorio De Sica.

This is a film comprised of three short stories with the same two actors playing different characters in various relationships. 

Sophia Loren! Marcello Mastroianni!

The first short is adorable (as is the chemistry between Loren and Mastroianni).

Mastroianni nails it in the third short. Highly Recommended.
