According to Deadline,
Chandler Kinney (Zombies 2, Lethal Weapon) and Maia Reficco (Evita, Kally’s Mashup) are set as the leads in Pretty Little Liars: Original Sin, a darker, present-day iteration of the popular 2010-17 series, from Riverdale and Chilling Adventures of Sabrina creator Roberto Aguirre-Sacasa; Lindsay Calhoon Bring (Chilling Adventures of Sabrina); Alloy Entertainment; and Warner Bros TV. Lisa Soper (Chilling Adventures of Sabrina) will direct the first two episodes. The series is scheduled to begin production later this summer at Upriver Studios in New York.
Written by Aguirre-Sacasa and Calhoon Bring, the reboot based on the bestselling books by Sara Shepard will feature a new story and new characters. Twenty years ago, a series of tragic events almost ripped the blue-collar town of Millwood apart. Now, in the present day, a group of disparate teen girls — a brand-new set of Little Liars — find themselves tormented by an unknown Assailant and made to pay for the secret sin their parents committed two decades ago…as well as their own. In the dark, coming-of-age, horror-tinged drama Pretty Little Liars: Original Sin, we find ourselves miles away from Rosewood, but within the existing Pretty Little Liars universe — in a brand-new town, with a new generation of Little Liars.
Kinney will play Tabby, an aspiring director and horror movie buff. Like the other Little Liars, Tabby’s hiding a secret.
