“Pretty Little Liars: The Perfectionists,” is based on the popular book series “The Perfectionists,” written by Sara Shepard, who also penned the No. 1 New York Times bestselling book series “Pretty Little Liars.” Everything about the town of Beacon Heights seems perfect, from their top-tier college to their overachieving residents. But nothing in Beacon Heights is as it appears to be. The stress of needing to be perfect leads to the town’s first murder. Behind every Perfectionist is a secret, a lie and a needed alibi. “Pretty Little Liars: The Perfectionists” is produced by Alloy Entertainment and Long Lake Media in association with Warner Horizon Scripted Television. I. Marlene King (“Pretty Little Liars,” “Famous in Love”) wrote the pilot and serves as executive producer with Leslie Morgenstein (“Pretty Little Liars,” “The Vampire Diaries”) and Gina Girolamo (“The 100,” “The Originals”).
“Pretty Little Liars” stars Sasha Pieterse (“Inherent Vice”) and Janel Parrish (“To All the Boys I’ve Loved Before” and is currently starring in a production of “Grease” in Toronto) are set to reprise their original roles in the new pilot. In “Pretty Little Liars,” Pieterse played Alison DiLaurentis, the former queen bee whose mysterious disappearance rocked the small town of Rosewood. Parrish played Mona Vanderwaal, Hanna Marin’s best friend, who was unmasked as the mysterious tormentor “A” at the end of the show’s second season, and ultimately beat uber-villain, A.D., at her own game.
