The cast of Lionsgate’s adaptation of Stephen King’s 1979 novel The Long Walk continues to expand as production gets underway. Deadline reports that Judy Greer (Halloween 2018, Cursed) and Mark Hamill (The Life of Chuck, The Fall of the House of Usher) are the latest stars to join the film.

Francis Lawrence, known for The Hunger Games: The Ballad of Songbirds & Snakes, is directing from a screenplay by JT Mollner (Strange Darling).

Originally published under Stephen King’s pseudonym Richard Bachman, The Long Walk is set in a dystopian future America governed by a totalitarian regime. The story centers around an annual walking contest in which 100 teenagers must walk non-stop under strict rules until only one remains alive. The novel follows 16-year-old Raymond Garraty and the diverse group of teens around him, each with their own secrets and motivations.

The film stars Garrett Wareing (Ransom Canyon), Tut Nyout (The Witcher: Blood Origin), Charlie Plummer (Spontaneous), Ben Wang (American Born Chinese), Jordan Gonzalez (Pretty Little Liars: Summer School), Joshua Odjick (Welcome to Derry), and Roman Griffin Davis (Jojo Rabbit). Cooper Hoffman and David Jonsson will also lead the ensemble.

Character details, including those for Greer and Hamill, have not yet been revealed.

Francis Lawrence is producing the film through his company, alongside Roy Lee, Cameron MacConomy, and Steven Schneider. Meredith Wieck and Erin Jones-Wesley are overseeing the project for Lionsgate, with Phil Strina handling negotiations for the studio. Filming will take place in rural Manitoba throughout the summer.

Stay tuned for more updates on this exciting project.
