One Night Only, the Will Gluck-directed romantic comedy starring Monica Barbaro and Callum Turner, opened in theaters on August 7, 2026, to mixed critic reviews that have anchored its Rotten Tomatoes Tomatometer in the mid-40s to low-50s range based on roughly 125 reviews. The consensus highlights an intriguing high-concept premise undermined by uneven world-building and tonal inconsistencies, despite praise for the leads’ chemistry and occasional charm. Early audience scores on the platform sit notably higher in the low-to-mid 70s for verified users, reflecting stronger popular appeal typical of studio rom-coms. With the film now in wide release, additional reviews are unlikely to shift the score dramatically, though any late surges in positive notices or audience-driven buzz could influence final certified tallies.
