"Long Bright River" series significantly adapts Liz Moore's novel

"Long Bright River," a new eight-episode series on Peacock, is based on Liz Moore's bestselling novel. Amanda Seyfried stars as Mickey Fitzpatrick, a patrol officer searching for her missing sister amid Philadelphia's opioid crisis. The series includes significant twists, such as Mickey's son being her sister's child and the killer being her partner. Co-creators Moore and Nikki Toscano adapted key moments from the book while allowing for changes in character development and plot details. Seyfried researched real police officers to portray Mickey's toughness, contrasting with her book character's more nerdy traits. The adaptation emphasizes community policing and the complexities of Mickey's character, who struggles with her role as a cop and sister.
