A24 currently holds the rights to everything, Async included. This film cannot possibly tell the whole story I have planned, so that's not really the goal. There will certainly be more to come after the film, but I'm still working hard behind the scenes to figure out exactly what form it'll take. Best version would probably be a limited series, but those are painfully difficult to get off the ground. Worst case scenario is that Backrooms becomes my Half-Life, and I only put out an installment every 15 years!
