**One Night Only**, a Will Gluck-directed romantic comedy starring Monica Barbaro and Callum Turner, opened August 7–9, 2026, to a disappointing $5.7 million from roughly 3,012 theaters—well below pre-release tracking in the mid-to-high single digits. Weak critical reception, limited audience interest in theatrical comedies amid a crowded summer slate, and heavy competition from *Spider-Man: Brand New Day* in its second weekend suppressed turnout and kept Friday estimates around $2.81 million. These confirmed results have driven overwhelming trader consensus toward the sub-$6 million outcome. An upset above $6 million would require substantial revisions to official weekend reporting or an unusually strong Sunday finish that contradicted all daily tracking, both highly improbable once final numbers are locked.
