Can a single night of temptation define the morality of a long-term marriage?

In short: Massy Tadjedin's 2010 directorial debut, Last Night, explores the thin line between emotional and physical infidelity. When a married couple spends a night apart following a fight, they each face distinct temptations. The film avoids easy moralizing, instead forcing viewers to confront the ambiguity of human desire and commitment.

The film follows Joanna and Michael Reed, a New York couple whose relationship is tested when Michael leaves for a business trip. While Michael is physically drawn to his co-worker Laura, Joanna encounters her ex-boyfriend Alex. Tadjedin, who wrote the script roughly four and a half years before release, initially conceived the project as a thriller but shifted focus toward the moral complexities of monogamy. She aimed to create characters that felt like real people, deliberately avoiding the tropes of 'monsters and angels' often found in cinematic depictions of cheating.

Casting was a central pillar of the production, with Tadjedin prioritizing chemistry to ensure the relationships felt authentic. Keira Knightley, returning to acting after a hiatus, anchored the project, while Eva Mendes was cast to bring warmth to a role that could have easily become a stereotypical temptress. The film’s international cast—including Sam Worthington and Guillaume Canet—used their natural accents, which Tadjedin felt added an organic quality to the story. Despite the director's efforts to create a balanced narrative, critics were divided; many praised the performances of Knightley, Canet, and Mendes, while Worthington’s portrayal of Michael faced significant criticism for appearing 'blank' or 'lifeless'.

The film's path to release was fraught with complications. Originally purchased by Miramax, the project was delayed following the company's sale to Filmyard Holdings. It eventually premiered at the 2010 Toronto International Film Festival and saw a limited theatrical release in the United States in May 2011. Commercially, the film struggled in the US, grossing less than $100,000, but found more success in foreign markets, ultimately earning over $7.7 million worldwide. Today, the film remains a subject of debate for its ambiguous ending and its refusal to provide clear answers about the characters' futures, leaving the audience to interpret the weight of their choices.
