Long Bright Riveris anchored by an A-list lead and features a lineup of seasoned TV actors poised for future success. The Peacock original series adapts Liz Moore’s New York Times bestselling novel of the same name. BeforeAmanda Seyfried stars in 2025’sThe Housemaid, she is playing the main character inLong Bright River. Set against the backdrop of Philadelphia’s opioid crisis, the story follows a police officer obsessively searching the streets for her estranged drug-addicted sister — all while a serial killer preys on the vulnerable women of the area.
While the show might change some elements, the novel has been described as more of a domestic drama than a traditional thriller — thoughthe threat of the next body being Mickey’s sister creates a sense of dread. WhileSeyfried awaits the production ofMamma Mia 3, she’s generating buzz for her upcoming role, and fans are eager to see her as a determined police officer hunting a killer. ThoughLong Bright Rivercan’t joinAmanda Seyfried’s best movies, perhaps it will be added to her growing list of great TV shows.
