In Staying Vertical, as in nearly all of French filmmaker Alain Guiraudieโ€™s tonically unorthodox work, the emphasis is on the abundant possibility of pairings and practices when people get horizontal.

Filled with quite literal chubby-chasing, Guiraudieโ€™s sexually anarchic romp The King of Escape (2009), for example, centers on a middle-aged gay man who falls in love and runs off with a 16-year-old girl, only to conclude with an all-male gerontophilic foursome. While the XXX action in the taut cruising-ground thriller Stranger by the Lake, the first of Guiraudieโ€™s movies to receive stateside release, may be exclusively man-on-man, the meat-rack habituรฉs in this 2013 film are refreshingly varied in age and BMI. Often the fluidity of desire matches the protean nature of his narratives, a quality thatโ€™s especially apparent in Staying Vertical โ€” a film that braids in, sometimes too desultorily, fairy-tale-like elements and surreal logic.

Like its predecessors, Staying Vertical is shot (primarily) in rural Southern France. Yet Guiraudieโ€™s latest also atypically includes detours to a city: Brest, the port town that itinerant Lรฉo (Damien Bonnard), a screenwriter whoโ€™s months past a deadline, returns to from time to time. As the film opens, Lรฉo, whose creative-class profession distinguishes him from Guiraudieโ€™s usual farm-laborer or blue-collar protagonists, is motoring through the winding byways of Lozรจre in a run-down Renault. He approaches a curly-haired young guy he sees on the side of the road: โ€œHave you ever thought about a movie career?โ€ Itโ€™s a dopey come-on, one made even more artless by Lรฉoโ€™s awkward posture, and coolly rebuffed by Yoan (Basile Meilleurat), who lives, as we later learn, with the ancient Marcel (Christian Bouillette) as the geezerโ€™s vaguely defined caretaker and likely catamite.

In Guiraudieโ€™s erotically elastic scenarios, though, rejection doesnโ€™t sting for long. Hiking through the hills, with the brutal pastoral beauty of the region accentuated by the widescreen compositions, Lรฉo spots Marie (India Hair), a flinty shepherdess who lectures him on the constant dangers posed by wolves, the totem animal of Staying Vertical. All the lupine talk serves as turn-on: In an abrupt and funny extreme close-up, Marieโ€™s hand is soon on Lรฉoโ€™s dungareed crotch. Just as quickly and unceremoniously, he becomes one of the mรฉnage, settling in to the farmhouse that Marie shares with her two towheaded little boys and her ogreish father, Jean-Louis (Raphaรซl Thiรฉry), who suggests the unfortunate son of John C. Reilly and Andrรฉ the Giant.

The coupleโ€™s bedroom scenes often begin with a screen-filling shot of Marieโ€™s vulva, a clear nod to Courbetโ€™s notorious painting The Origin of the World. Those adoringly, classically framed genitals, however, soon resemble a gruesome crime scene: Footage of a newborn being pushed out of its motherโ€™s vagina spares no blood, excreta or goo. This blast of trying body horror is immediately followed by that once-viscous creature now as a cute, onesie-clad baby boy, dandled by Lรฉo, whoโ€™ll shortly be the unnamed infantโ€™s sole caretaker after Marie departs with her two older kids.

For a while, thereโ€™s a kind of order to Lรฉoโ€™s increasingly shambolic existence, signaled by the recurrence of through-the-windshield shots as the ungainly scriptwriter drives back and forth, his kid usually in tow, from the home he now uneasily occupies with Jean-Louis to the fractious residence of Yoan and Marcel to a micro-hotel room in Brest โ€” where, in one of several dreamlike scenes, heโ€™s mobbed and denuded by a horde of homeless men. Lรฉoโ€™s also a king of escape, but one who can never fully assume the throne. In his most outrรฉ odyssey, he slowly paddles down a stream, his baby an incongruous bundle on the floor of a canoe, for an appointment with a yurt-dwelling shaman, Dr. Mirande (Laure Calamy), a healer with a terse bedside manner.

That fluvial episode exemplifies the pleasures of Guiraudieโ€™s unpredictable scenarios; the setting, thick with vegetation, recalls both the promise and the menace that imbued the arcadian grove where sex is sought in Stranger by the Lake. As always with Guiraudieโ€™s films, Staying Vertical shrewdly (and often hilariously) captures both the seriousness and the absurdity of sex, particularly when Lรฉo obliges miserable Marcel with a dying wish: The younger man tenderly, but no less resolutely, barebacks the old guy, Lรฉoโ€™s determined thrusting scored to ludicrously loud prog-rock noodling.

But while overwhelmed Lรฉo tries to maintain the position of the movieโ€™s title โ€” standing upright amid so much chaos or remaining erect with his various bedmates โ€” some events are defined not by the exhilaration of libidinal lawlessness but by fatiguing whim. Plug-ugly Jean-Louisโ€™ late-act blunt propositioning of Lรฉo, for instance, comes as no surprise โ€” Guiraudieโ€™s movies are often populated with such age- and beauty-discordant potential pairings โ€” but now seems almost de rigueur for the director. But while I grew restless in Staying Verticalโ€™s final 30 minutes, my fear that Guiraudie was beginning to rely too heavily on the same propriety-pushing situations was quelled by Staying Verticalโ€™s knockout ending โ€” one that imagines a different, almost certainly doomed, communion between two different species.
