A24 has put out a cinema-only teaser, shown ahead of Resident Evil, for a horror film called Slayground, along with a countdown site, runlikehell.com, that ticks down about 30 days. The teaser is built as surveillance footage from inside a haunted attraction, the setting the film takes its name from, and A24 has not released a synopsis, cast list, or release date.
The teaser and the countdown site
The teaser is presented as security-camera footage pulled from inside the attraction, and it ends on the address runlikehell.com. A24 played it only in theaters rather than posting it online, part of a deliberately cryptic rollout. That site now carries the marketing: it opens on a wall of black-and-white surveillance feeds from named rooms, including Tomb of Doom, Satanor’s Lab, Portrait Room, a hallway, a kill chamber, and a dungeon, each with a running timestamp. Some feeds show figures moving through the sets, while others cut to static. The clips are short, grainy, and looped, styled like real security footage from the attraction’s rooms. Below the feeds, a clock counts down roughly 30 days, which points to more news around mid-October, and an email signup asks visitors to opt in to A24 promotional materials. A24 has not said what the countdown leads to, and it has not released a poster or key art.
The reported director, cast, and plot
A24 has not put out an official synopsis or cast. According to trade reports, Slayground is written and directed by Jeremy Saulnier (Green Room, Rebel Ridge) and was previously titled October, reportedly changed because A24 would not hold the release for that month. The title is not connected to the 1983 film or the Donald E. Westlake novel of the same name. The reports say it follows a mass-murder suspect, played by Cory Michael Smith, who goes on the run on Halloween, with a cast that includes Imogen Poots, James Badge Dale, Matty Matheson, Chase Sui Wonders, Sophie Wilde, Young Mazino, and Stephen Root, and a score by Trent Reznor and Atticus Ross. The same reports put the runtime at about two and a half hours and say the film has been in post-production for roughly a year. None of that is confirmed by A24, and no release date has been set.
Slayground’s fictional haunt and its workers
For the haunt world, the draw is the setting. Slayground is named for the fictional haunted attraction where its lead character works, and the teaser plays out on that attraction’s cameras, which puts a working haunt and its staff at the center of a major studio’s horror release. Slayground centers on that setting, putting the sets, the scare actors, and the job itself on screen. Readers curious about that work can see our guide to how to become a scare actor.
If the countdown holds, more on Slayground should surface around mid-October. For the rest of the season’s horror on screen, see our 2026 Halloween streaming guide. A24 is also behind Backrooms, which recently started streaming.
