Megan Gallagher's 'All Her Fault': A Thrilling Exploration of Motherhood and Modern Parenting
By Editor • August 15, 2026 • 3 min read
Megan Gallagher has made her mark in the world of television adaptations, most recently with the gripping series 'All Her Fault,' which has quickly become Peacock’s most-watched original show, racking up an impressive 46 million viewing hours in just three weeks. Based on Andrea Mara’s novel, the series features Sarah Snook as Marissa, a distraught mother whose life spirals out of control when her son, Milo, goes missing, leading to revelations that shake her family to its core.
Gallagher, who also serves as the executive producer, has a knack for bringing complex narratives to life. In 'All Her Fault,' she dives deep into the emotional turmoil of motherhood, particularly the silent struggles that many women face, even when they are in committed relationships. This theme resonates strongly with viewers, sparking conversations about the realities of parenting in today’s world.
Initially, Snook was hesitant to take on the role, but Gallagher’s offer to shoot in Australia was a game-changer. "For the majority of the series, Marissa is in DEFCON 5 trauma," Gallagher explained. She emphasized the need for an actress who could convey the depth of the character beyond just the emotional breakdowns. Snook fit that bill perfectly, bringing both sophistication and authenticity to the portrayal of a mother in crisis.
Interestingly, the series was set in Chicago, despite being filmed in Australia. Gallagher, who hails from America but resides in Norway, noted that the decision to choose Chicago was intentional. She aimed for a setting that felt relatable to a broad audience, steering away from the more recognizable cities like New York and Los Angeles. "Chicago was very Middle America and more universally understandable," Gallagher said, highlighting the adaptability of Mara’s narratives.
In a notable departure from the source material, the role of the investigator, originally female, was given to actor Michael Peña as Detective Alcaras. Gallagher explained that this change was meant to introduce a positive male presence in a story that critically examines male involvement in family dynamics. Drawing from her personal experiences, Gallagher wanted to depict a father who actively engages in parenting, countering the often negative portrayals of men in similar narratives.
One of the most significant discussions around 'All Her Fault' has centered on its honest representation of motherhood. Gallagher expressed her delight at the overwhelming response from audiences, particularly women who identified with the show’s themes. "I knew it would resonate, but I did not know it would resonate as much as it did," she reflected. The series sparked conversations on social media, with viewers dissecting its portrayal of family life, and one TikTok comment humorously noted the portrayal of two notably flawed husbands, emphasizing that infidelity was not the central issue here.
As for the series finale, Gallagher confirmed that the conclusion remained faithful to the book, delivering a satisfying and impactful resolution. The twists, including the dramatic revelations surrounding Milo’s abductor and the fate of Marissa’s husband, Peter, were crafted to maintain the narrative’s tension and emotional weight. "So no one considered anything else ever, because you don’t mess with something [that good]," she stated, underscoring the series’ commitment to its source material while also introducing fresh elements.
Looking ahead, Gallagher is set to adapt another of Andrea Mara’s novels, titled 'Such a Nice Girl,' which explores female friendship across generations. This new project promises to delve into the complexities of relationships between mothers and daughters, all while maintaining the engaging storytelling that Gallagher has become known for.
In a landscape filled with adaptations, Gallagher’s work stands out not just for its thrilling plots, but for its powerful commentary on the realities of modern-day parenting, making 'All Her Fault' a must-watch series that resonates far beyond the screen.
