I hope this does well as Kane pixels, the guy who made all those backrooms videos was involved in this and A24 approached him and involved him to make it.

The main actor here is Chiwetel Ejiofor who was the operative in Serenity and the main guy in 12 years a slave so well known. Let's see as if they allow Kane to convey the horror of an endless maze that is based of something slightly familiar, it might work out.
