The series, characterized as a suspense thriller, revolves around the narrative of Mickey (played by Seyfried), a police officer tasked with patrolling a Philadelphia neighborhood severely impacted by the opioid crisis. As a sequence of murders unfolds in the area, Mickey becomes cognizant that her personal history may be intertwined with the case.

Liz Moore is collaborating with Nikki Toscano, known for her work on “The Offer” and “Hunters,” in adapting the book for the screen. Both Moore and Toscano will serve as executive producers, with Toscano also taking on the role of showrunner.


In a joint statement, Moore and Toscano conveyed, “‘Long Bright River’ tells a story about the collective power of an underserved community. We are thrilled that Amanda Seyfried will lead this series about how those initially perceived as victims can band together to regain their power.” The series draws inspiration from Moore’s family background and her involvement with harm-reduction and community-service organizations in Philadelphia, aiming to depict with compassion the lives of those grappling with addiction and their supportive family members.

This project marks Seyfried’s latest venture in a lead role for a limited series. Having previously earned an Emmy and a Golden Globe for her performance in Hulu’s “The Dropout,” where she portrayed disgraced Theranos founder Elizabeth Holmes, Seyfried continues to make her mark in the television industry. Her recent work includes starring in Apple TV+’s limited series “The Crowded Room.” Seyfried has an extensive television repertoire, including roles in “Big Love,” “Veronica Mars,” and the revival of “Twin Peaks.” On the cinematic front, she received an Oscar nomination for her role in “Mank” in 2021 and has starred in iconic films like “Mean Girls,” the “Mamma Mia” franchise, and the 2012 adaptation of “Les Misérables.”

In addition to her starring role, Seyfried will also serve as an executive producer for “Long Bright River.” Executive producers for Original Film include Neal H. Moritz, Pavun Shetty, and Amanda Lewis, while Amy Pascal will executive produce through Pascal Pictures. The first episode will be directed and executive produced by Hagar Ben-Asher. The production will be a collaboration between Sony Pictures Television and UCP.
