It's time to "no clip out of reality" and into...somewhere else.

Following on from a very eerie teaser we now have a full trailer for A24's Backrooms , Kane Parsons' feature length adaptation of his viral YouTube series which was in turn inspired by a 4chan creepypasta.

In the video above we see a man (Chiwetel Ejiofor) discovering a doorway to what appears to be another dimension in the basement of a store. Cue an exploration of a horrifying yellow liminal space where the rooms are either cavernously large or nightmarishly small — and possibly not unoccupied.

Backrooms stars Chiwetel Ejiofor, Renate Reinsve, Mark Duplass, Finn Bennett, and Lukita Maxwell.

Backrooms is in theaters May 29.
