Early screenings for the Will Gluck-directed romantic comedy “One Night Only,” starring Monica Barbaro and Callum Turner, have produced mixed critic responses ahead of its August 7 wide release, with the Tomatometer hovering near 50-55% based on initial reviews. The high-concept premise of a single sanctioned night for unwed intimacy has drawn praise for the leads’ chemistry yet criticism for tonal inconsistencies and dystopian elements that some find off-putting. Pre-release buzz from guild and festival circuits remains limited, leaving room for the score to shift as additional notices arrive post-opening. Traders are watching for how mainstream outlets balance the stars’ appeal against the film’s divisive narrative.
