Peacock is bringing crime, suspense, and emotional depth to the screen with Long Bright River, a gripping new limited series premiering on March 13, 2025. Based on Liz Moore’s bestselling novel, the show blends police drama, psychological thriller, and family drama, making it one of the most anticipated book-to-screen adaptations of the year.
A Story of Family, Addiction, and Survival
Set in the opioid-ravaged streets of Kensington, Philadelphia, Long Bright River follows Mickey Fitzpatrick (Amanda Seyfried), a dedicated police officer whose duty and personal life collide when her estranged sister, Kacey, goes missing. As a series of murders shakes the city, Mickey fears Kacey might be one of the victims — or somehow involved. As she navigates a corrupt system and her own troubled past, she must race against time to uncover the truth.
The series is based on Liz Moore’s critically acclaimed novel, first published in 2020. The book, spanning 482 pages, was praised for its emotional depth and raw portrayal of addiction, earning a place on several 'Best Books of the Year' lists.

Cast, Release Date, and What to Expect
Starring Amanda Seyfried, Long Bright River also features Nicholas Pinnock (as Truman Dawes), Ashley Cummings (as Kacey), Callum Vinson, and John Doman. The series is produced by Sony Pictures Television and Universal Content Productions, with Liz Moore and Nikki Toscano serving as executive producers.

A Dark and Gritty Adaptation
With its tense atmosphere, layered storytelling, and complex characters, Long Bright River is expected to deliver both mystery and emotional weight.
