Mark Hamill oversees a very deadly journey in the trailer for The Long Walk, the film adaptation of Stephen King‘s novel.

Director Francis Lawrence’s dystopian horror feature stars Cooper Hoffman as Raymond Garraty, David Jonsson as Peter McVries, Charlie Plummer, Ben Wang as Hank Olson, Roman Griffin Davis, and Judy Greer.

The Long Walk centres on an annual contest in which a hundred teenage boys set out on the titular trek, a journey that requires them to maintain a quick pace without stopping and ends with just a single survivor. The prize is determined by the winner of the competition. Hamill portrays The Major, the leader of the secret police force known as the Squads, who enforces the rules of the Walk.

Lawrence directs from a script by JT Mollner, itself an adaptation of King’s 1979 novel, though it was originally published under his pseudonym, Richard Bachman. The story was inspired by the loss of young men’s lives to the Vietnam War, which was ongoing when King attended university and was writing it.

Lawrence serves as producer alongside Roy Lee, Steven Schneider, and Cameron MacConomy.

The Long Walk is scheduled to be released in the United States by Lionsgate on September 12th, 2025. Watch the trailer below:
