A Tragedy of Manners. This is how bestselling author Patrick DeWitt’s satirical novel “French Exit” was billed upon its publishing in 2018. That description is also spot-on for this elegant, droll, and heartbreaking screen adaption, directed with crafty command and confident style by Azazel Jacobs. Scripted by DeWitt himself with the authority of a wordsmith possessed by his own material, the fiendishly disarming “French Exit” widely and nonchalantly grins out its death-tinted tragedy throughout, but with a fake smile, a severe code of conduct, and not a hair out of place. It’s only after you spend enough time in the company of its handsomely dressed, oddball group of characters—led by a sexagenarian New York widow spending the final crumbs of her wealth in Paris—that you notice their bleeding bruises beneath this strangely captivating, clever little film’s perfect surface.
