A renaming and reworking by Atom Egoyan of the French film Nathalie by Anne Fontaine. Despite the pedigree (Egoyan, if you need reminding, has signed such tony items as Ararat, The Sweet Hereafter, Exotica, among others), this would fit comfortably on the Lifetime Movie Network: a suspicious wife sics a high-end escort onto her husband as a temptation, a test. True, the escort’s oral reports have a graphicness you mightn’t hear on LMN (“I could feel he was excited through his pants,” “I put my tits in his face”), and Julianne Moore, as the midlife gynecologist who lives in a luxurious red box with musicologist Liam Neeson, gives you more acting per second than you get from Judith Light or Joanna Kerns, and the expanses of flesh (not just the always game Moore, but also the uninitiated Amanda Seyfried as the escort) are decidedly “R”-rated, though these are matters of degree, not substance. The odor of cheesiness, both the main attraction and the main limitation of the film, never dissipates, only intensifies: the escort, gradually proving herself even crazier than her client, develops an at first reciprocated crush on the woman and then, when rebuffed, turns her attentions to the latter’s teenage son. (Fatal Attentions might have been a franker title.) Neither of the women, in fairness, takes further leave of senses than Egoyan. The Canadian locale only firms up the Lifetime affinity.
