Madeline Mackenzie is the fierce, fast-talking, impeccably put-together mother at the center of Monterey's wealthy social swirl in Big Little Lies — a woman whose relentless energy and need for control mask deeper insecurities about her marriage, her daughters, and her own choices. Madeline is the engine of the show's social drama.
Her arc peels back the perfect façade to reveal regret, jealousy, and fierce loyalty, as she and her circle of mothers are bound together by a death and the lies they tell to protect one another. Madeline's sharp tongue and bruised heart make her compulsively watchable.
Reese Witherspoon — also a producer — anchors the star-studded HBO limited series.
