One Night Only 2026

One Night Only (2026) is an American romantic comedy directed by Will Gluck, starring Monica Barbaro and Callum Turner as two New Yorkers searching for something more meaningful on the most chaotic night of the year. The movie is set in a fictionalized version of New York where premarital sex is legally permitted for just one night each year, turning the annual event into a frantic social phenomenon.

Recently dumped Owen and hopeful romantic Allie meet during the madness, but a series of misadventures keeps pulling them apart just as they begin to connect. Released theatrically in the U.S. on August 7, 2026, the 102-minute R-rated comedy has attracted attention for its unusual premise, large ensemble and string of celebrity cameos.

Storyline & Plot Analysis

The One Night Only storyline takes place in a society where single people have only one officially sanctioned night each year to have sex before marriage. The unusual rule creates a frenzy across the city, with people planning the night months in advance.

At the center are Allie, a romantic looking for a genuine connection, and Owen, who has recently been dumped. When the two meet, there is an immediate spark, but their night does not go according to plan.

A series of wrong turns, unexpected encounters and separate side adventures repeatedly prevents them from staying together. While everyone else seems focused on making the most of the city’s annual celebration, Allie and Owen gradually discover that what they actually want may have little to do with the night’s official purpose.

The premise gives the film room to poke fun at dating culture, social expectations and the pressure to find a romantic or sexual partner on a designated night. At its core, however, the movie remains a meet-cute romantic comedy about two people unexpectedly falling for each other.

Production Details & Behind-the-Scenes

Will Gluck directed and produced One Night Only from a screenplay by Travis Braun, with Gluck also contributing to the script. Jacqueline Monetta produced alongside him through Olive Bridge Entertainment. Universal Pictures distributed the movie theatrically.

The film was shot in New York City, with cinematographer Yaron Orbach handling the visuals. Its slightly fictionalized version of New York allows the production to exaggerate the city’s annual celebration while retaining recognizable urban locations and romantic-comedy energy.

One of the movie’s biggest production talking points is its unusually large collection of celebrity cameos. Among the appearances are Glen Powell, Sydney Sweeney, Pete Davidson, Bobby Cannavale, Julia Fox and Nicholas Braun, giving the film plenty of surprise moments beyond its main ensemble.
