This article contains spoilers for “Long Bright River,” now streaming on Peacock. Two years before Liz Moore's novel "Long Bright River" ever hit shelves in 2020 and became a bestseller - and one of Barack Obama's top books of the year - she was approached by different producers.

Amanda Seyfried dishes on her new Peacock limited series "Long Bright River" and fulfilling her dream of playing a police officer, including a traffic stop turned sideways during a ride-along with a real cop.

Long Bright River is a new Peacock TV show, which is an adaptation of the 2020 book of the same name by Liz Moore. The show is not based on a true story but takes inspiration from the author's life.
