Alain Resnais, that gentleman subversive, has been playing serious tricks on moviegoers for a half-century, since Hiroshima Mon Amour and Last Year at Marienbad. In the delightful anarcho-romantic comedy Wild Grass, a happily married man (André Dussollier) finds a wallet belonging to a woman (Sabine Azéma), and the two strike up a dangerous friendship. You could easily relax in the warmth of the story, its charming old je ne sais quoi unless you notice the quietly unrealistic color scheme, the geometric placing of extras, the little explosions of rage or madness. It's a cocktail-party movie with a Molotov-cocktail finish: a tribute to the 88-year-old auteur's artistry and his con artistry as well.
