The work of late author Sir Terry Pratchett will live on in the form of a feature-length film based on his popular novel Wee Free Men, The Jim Henson Company announced Tuesday.

Both The Jim Henson Company and Narrativia have partnered together to bring Wee Free Men, part of the popular Discworld series, to life. Pratchett’s daughter, Rhianna co-director of Narrativia and a prominent video game scribe who has worked on projects like 2013’s Tomb Raider reboot and its 2015 WGA Award-winning sequel, Rise of the Tomb Raider will pen the film adaptation’s script.

Wee Free Men revolves around Tiffany Aching, a young witch who, armed with only a frying pan and her wit, grapples with an impending, nightmarish threat from the monsters of Fairyland. She enlists the help of the local Nac Mac Feegles, a group of six-inch-tall men, as the nefarious Queen of Fairyland wreaks havoc.

Jim Henson’s son, Brian, will serve as producer on the film. Executive-producing on the Henson side is Vince Raisa, while Rhianna, Rob Wilkins, and Rod Brown will also produce.

“I’ve loved the Jim Henson Company’s work all my life,” Rhianna said of the project in a press release. “…it’s a great honor to team up with them and bring Wee Free Men to the big screen.”

Perhaps best known as the creators of the wildly popular Muppets franchise, The Jim Henson Company, which has won 50 Emmy Awards and nine Grammy Awards, also produced films like The Dark Crystal, Labyrinth, and MirrorMask. Narrativia, launched by Terry in 2012 as an independent production company, owns and controls the multimedia and merchandising rights to all of the writer’s works, which have sold more than 85 million books worldwide to date.

A release date and casting details for the Wee Free Men movie have yet to be announced.
