The first thing Will Gluck’s new film hands you is a colour. Aquarium-green neon pools across a late-night food cart, catches on wet asphalt, and turns an ordinary stretch of sidewalk into something feverish and slightly unreal. A young woman leans on the counter; a man in a grease-flecked apron leans back toward her. The shop signs, the parked cars, the steam off the griddle all glow in the same sodium-and-neon palette, the look of a city that has decided, for a few hours, to stop pretending to sleep.

That over-lit metropolis is the entire idea. One Night Only imagines a New York governed by a single civic rule: on one designated night of the year, single people are allowed to have sex, and on every other night they are not. The logline sounds like a party movie, and some of the marketing will sell it that way. What the frame keeps insisting on instead is scarcity, and the loneliness underneath it, a whole city licensed to connect for twelve hours and visibly unsure what to do with the permission.

Monica Barbaro and Callum Turner are the two faces the film organizes that anxiety around, and the casting is the clearest statement of intent here. Barbaro, coming off an awards-season breakthrough, plays Allie as a hopeful romantic who wants the night to mean something; Turner, all rumpled defeat, plays Owen, recently dumped and moving through the crowd like a man who has already decided the evening will disappoint him. They are, the film suggests, possibly the only two people in the city chasing more than a quick encounter, which is exactly what keeps pulling them apart. Neither is a marquee comic lead by trade, and that miscasting-against-type is the bet: two dramatic actors playing sincerity straight inside a high-concept farce.

Gluck knows this register better than almost anyone working in studio comedy. He built Easy A on a teenager’s manufactured reputation and turned Anyone But You into a surprise theatrical hit by trusting two attractive people to bicker at length. He reportedly rewrote Travis Braun’s Black List script after that success, treating the dystopian conceit as the next mutation of a formula he has been refining for a while: put charismatic performers in a pressurized situation and let the constraint do the plotting. The constraint here is time. Twelve hours, one rule, and a city built to run out the clock.

The production design is doing the heavy lifting the premise needs. This is not our New York but a curdled, ordinance-bound version of it, and the film renders the difference through light rather than exposition, through neon curfews and the crowd behavior of people rationed to a single sanctioned night. Gluck stages the couple’s near-misses as a nocturnal relay across boroughs, a series of missteps and side quests that keep them racing toward and away from each other. The visual argument is consistent: desire under regulation looks garish, exhausting and a little sad, however loudly the soundtrack insists everyone is having fun.

What the film has not yet shown it can do is make the conceit outlast its own hook. High-concept romantic comedy lives or dies on whether the world-building is more than a delivery system for one joke, and a premise this blunt can curdle into leering just as easily as it can turn tender. The supporting bench is deep enough to crowd the two-hander it depends on, and no critic has seen the finished cut, so the question of whether the dystopian frame says anything about modern intimacy or simply rents its shape remains open. A trailer can promise chemistry; it cannot promise that twelve hours of contrivance will resolve into a reason to care.

Around the leads, Gluck has stacked an ensemble that reads like a downtown guest list. Molly Ringwald appears as Owen’s mother, Linda, with LeVar Burton as her partner; Maya Hawke, Julia Fox, Este Haim, Ziwe, King Princess and Ben Marshall fill out the crowd of the licensed and the lonely. Braun’s original screenplay drew Gluck in enough to rework it himself, and he produces through Olive Bridge Entertainment. The result is being positioned as a mid-summer counter-program, an R-rated adult comedy aimed squarely at audiences who aged out of the season’s franchise slate.

Universal Pictures releases One Night Only in United States theaters on August 7, 2026, rated R and running 102 minutes. Spain follows on August 26 under the title Una noche al año, and Brazil on August 27 as Só Por uma Noite; a Mexican theatrical date has not been confirmed at the time of writing. The tagline promises that twelve hours can change everything. Whether that is a threat or a wish is, for now, the most interesting thing the film is keeping to itself.
