Caught between sophisticated comedy and silly fluff, between Hitchcockian mystery and zany amateur sleuth caper, A Private Life (Vie Privée) is a lot more fun than it probably deserves to be thanks to the disarming chemistry of its seasoned leads, Jodie Foster and Daniel Auteuil. Rebecca Zlotowski’s latest doesn’t have the intoxicating sun-kissed sensuality of An Easy Girl or the emotional complexity of Other People’s Children, her last two films. This one is too busy careening all over the tonal map for any of that. What it does have is the French director’s customary light touch; it’s chaos with charm.

Foster’s French — at least to these ears — sounds impeccable and this is her first feature in the language since 2004’s A Very Long Engagement. She jumps into it with a spiky vitality and an unexpected playfulness that buoy the movie as much as Zlotowski’s zippy direction.
