We Were Liars: Release date news, cast details, streaming details and more about Prime Video's upcoming psychological thriller adaptation

E. Lockhart's popular YA novel "We Were Liars" is making its way to television. Amazon Prime Video has commissioned an eight-episode series adaptation. The adaptation will stay true to the central narrative of the novel while broadening its universe to incorporate viewpoints beyond that of the main character.

Published in 2014, We Were Liars is a psychological horror novel aimed at young adults, written by E. Lockhart. The book has garnered significant praise and won the Goodreads Choice Award for Best Young Adult Fiction. Additionally, it was recognized as one of the ALA Top Ten Best Fiction for Young Adults in 2015.

Set on an imaginary private island in Massachusetts, this series centers on a wealthy family and their complex, sometimes dark secrets. It tells the story of Cadence Sinclair Eastman, a teenager grappling with amnesia from a peculiar accident. The show delves into themes of trauma, privilege, and denial.

Julie Plec and Carina Adly MacKenzie, known for The Vampire Diaries and Roswell, New Mexico, created the TV adaptation, which combines modern flair with profound emotional depth.

Release date of We Were Liars

The series is scheduled to premiere on June 18, 2025, and Prime Video is expected to release all eight episodes at once on that date, adhering to the company's usual binge-watch approach.

The news was preceded by a teaser trailer and a series of first-look production images. The teasers suggest that the series will be a visually stunning, dramatic take on the same mood as the book. Pre-release images appear to focus on emotional and physical loneliness among characters, remaining faithful to the novel's exploration of loss, memory, and deception.

Where can you stream We Were Liars

We Were Liars will be available exclusively on Amazon Prime Video. A Prime subscription is required to view the series. To date, there has been no discussion of a staggered international release, so it appears that it will be launched everywhere simultaneously.

Prime Video is marketing the series as a YA psychological thriller while also highlighting its crossover appeal due to the thematic elements and the notable performances presented. The decision to release all episodes simultaneously further indicates the platform's confidence in the binge-worthiness of the narrative.

Cast: Who's who in We Were Liars

Emily Alyn Lind portrays the title heroine, Cadence Sinclair Eastman, an heiress trying to make sense of her life. She is joined by Shubham Maheshwari as Gat Patil, Cadence's would-be love, and Esther McGregor as Mirren Sinclair Sheffield, another of the "Liars." Joseph Zada portrays Johnny Sinclair Dennis, part of the main teen group.

The adult cast features experienced actors such as Mamie Gummer, David Morse, Candice King, Caitlin FitzGerald, Wendy Crewson, and Rahul Kohli. They represent the older generations of the Sinclair family, all of whom find their place within the themes of inherited wealth and bottled emotions in the plot. Each performer contributes a high level of depth to the family dynamics that serve as a focal point for the unfolding mystery.

Plot and setting of We Were Liars

We Were Liars takes place primarily on Sinclair-owned Beechwood Island. The show centers on Cadence and her three cousins, who call themselves "the Liars." Cadence suffers from partial amnesia due to an accident during one of their summer vacations. While she tries to recover her memory, secrets are revealed.

The television adaptation will remain faithful to the psychological framework of the novel but will incorporate broader perspectives. The series will contrast the book's first-person point of view by allowing the audience to explore other characters' motivations and emotional perspectives within the Sinclair family. This adjustment aims to provide a more intimate look into the factors behind the family's disintegration.

Production background of We Were Liars

The book We Were Liars was discussed for a movie adaptation shortly after its publication in 2014. However, its rights were occasionally reverted to E. Lockhart. Interest in its adaptation was renewed during the COVID-19 pandemic, and Prime Video acquired its rights under a series of terms.

Production is part of Universal Television, a unit of Universal Studios Group. Julie Plec and Carina Adly MacKenzie serve as showrunners and executive producers. E. Lockhart is an executive producer who ensures the storyline remains as close to its true tone as possible.

The decision to create it as a limited series rather than a feature film allows the story more freedom to explore the book's themes on a more intimate level.

Trailer and first look of We Were Liars

Amazon has already released a teaser trailer for We Were Liars, giving us a glimpse of the series' moody, atmospheric aesthetic. Without revealing any spoilers, the trailer features voiceovers from Cadence alongside dramatic shots of Beechwood Island. There is a palpable sense of tension, emotional complexity, and visual contrast—washed-out beaches intertwined with the secrets of torrential weather.

Initial promotional material teases a blend of intense drama and intrigue. The series seems to adopt a slow-burning approach, focusing on character interactions before unveiling its major plots. While overall reviews and reactions are still limited, the initial response to the teaser has been cautiously encouraging.

With its June 2025 premiere date, We Were Liars arrives more than a decade after the novel's initial impact on the YA scene. The series aims to bring the central story to life while adding new depth to secondary characters and subplots. Fans will experience a blend of psychological suspense, emotional turmoil, and a haunting atmosphere.

Whether you're a veteran reader of the book or a newcomer to the series, the adaptation aims to present We Were Liars through a sophisticated and modern lens. With no announcement regarding the release of a second season, the limited-series format suggests a standalone story that remains faithful to the book's ending.
