Aguirre-Sacasa is set to pen the script for a reboot of PLL, which will feature all new characters and a new story, according to multiplereports.
There's no network yet attached to the project, although Deadline reports that HBO Max could be a possible destination, considering they are already working on developing a reboot of Gossip Girl and the original series is available on the platform.
The original Pretty Little Liars -- created and developed by I. Marlene King, based on the book series of the same name by author Sara Shepard -- debuted in 2010 and aired for six seasons before coming to an end in June 2017.
The show had two attempted spin-offs, including Ravenswood and Pretty Little Liars: The Perfectionists, but both series ended after one season.
Lucy Hale, who was a star of the original series, spoke with ET's Katie Krause back in May and addressed the possibility of someone creating a PLL reboot or adapting it as a film in the future.
"We're in a quarantine that we thought would last a couple weeks. Anything is possible at this point," Hale said. "I don't rule anything out, [but] I feel like we'd need a little more time to pass. I feel like we would get more out of it if we were, like, 10 years down the road."
"I feel like they're gonna do a spinoff or something before then. I don't know. I'm so protective of this show," Hale continues. "So I feel like when the time comes that they want to do it with a whole new cast, I might have to produce it because I'm way too protective of it."
