A24 Teases Backrooms Trailer With Posters Quoting the Original 4chan Lore

Overview

• A24 shared new character posters for Backrooms that tease a fresh trailer and reaffirm a May 29, 2026 theatrical release.
• The artwork lifts the opening line “If you’re not careful” from the 2019 4chan post, with earlier materials using “You are not supposed to be here.”
• Fans analyzing the posters pointed to shifting yellow tones and bits of blue painter’s tape as nods to Backrooms lore, Kane Parsons’ shorts, or The Caretaker’s album art.
• The feature is a loose adaptation directed by YouTube creator Kane Parsons from a script by Will Soodik, starring Renate Reinsve and Chiwetel Ejiofor with Mark Duplass, Finn Bennett, Lukita Maxwell, and Avan Jogia.
• An official synopsis says a therapist enters an otherworldly maze to find a missing patient, and coverage highlights the challenge of scaling the shorts’ first‑person style and creature designs for theaters.
