Overview

• The Natasha Allergy Research Foundation criticized a sequence involving a severe allergy and said it will contact the filmmakers, calling the portrayal triggering and dangerous.
• The film, a new take on The War of the Roses from director Jay Roach and writer Tony McNamara, opened August 29 and centers on a marriage that devolves into escalating conflict.
• Cumberbatch and Colman described a physically demanding, largely practical climactic set piece shot over several days with one‑take destruction and foam prop fruit.
• Although set in California, production used U.K. locations including the South Devon coast, Ascot Racecourse, and interiors built at Pinewood Studios, according to the production team.
• Cumberbatch noted a brief on‑set “speed bump” with Colman before the pair checked in as friends, as early reviews praise the leads and question the film’s tonal balance.
