My Worst Nightmare (2011)

Agathe (Isabelle Huppert) is an uptight, impatient art dealer who lives in an expensive Parisian apartment with her wealthy publisher husband, Andre Dussollier. Patrick (Benoit Poelvoorde) is a skirt-chasing, unemployed single father who lives in his van with his son. Their lives would never intersect except that their two sons are best of friends and her husband has hired Patrick to remodel their apartment. Hilarity ensues as this odd couple relationship turns into Agathe's worst nightmare.
