It’s a stretch but Mark Duplass’ character, Phil, is a scientist and researcher for a company that did imaging research before creating/discovering the doorway into the Backrooms. I’d like to think that at one point of his career he was an x-ray tech of some sort.

So kinda, sorta, maybe a movie about a x-ray tech as I know nothing but the bare minimum about what x-ray techs do so I’d like to believe they explore weird parallel dimensional limbo spaces.
