Film Suggestions if you Liked This One
I have not seen this film; i found the imdb site for it because i'm interested in corine serreau, the director.
from reading the plot, I would also recommend you see French Twist and Preparez vos Mouchoirs, Too Beautiful for You, and and Mama There's a Man in your Bed.The first 2 have a story correlation with Why Not?; the latter two could have been titled the same as this one and are about unlikely relationships.
