Outside of an escape over the rooftops of Paris, most of the scenes take place indoors as the film becomes more and more theatrical, leading to a climax with all the characters ending up onstage. Ugo and Pierre have a hilarious duel with vodka for Camille before all the loose ends are conveniently tied up.
Director Jacques Rivette's latest film is lighter and more accessible than his previous works, like the masterful "La Belle Noiseuse." Rivette, a former critic for Cahiers du Cinema who first came to prominence as part of the French New Wave, co-wrote "Who Knows?" with witty repartee and verbal encounters staged with effervescent amusement.
As with many of Rivette's films, "Who Knows" has an extended running time; even with the considerable charms of the cast, the slight story is drawn out at over two-and-a-half hours.

Written by Christine Laurent, Pascal Bonitzer and Jacques Rivette. Produced by Pierre Grise Productions. A Sony Pictures Classics release. Comedy. French-language; subtitled. Not yet rated.
