We Used To Live Here, which was just acquired by Netflix.
The movie is based on a novella published as part of Reddit’s No Sleep feature. The psychological thriller definitely sounds like it’s going to be a scary movie!
Here is the synopsis, via Deadline: “A homeowner gets a knock at her door while her partner is at work. It’s a husband, wife and kids. They are peculiar, and the man says he once lived in the house and wanted to take a look around. The homeowner is just getting used to the old house herself, and things get progressively weirder as a snowstorm strands the visitors as they just won’t leave. The homeowner can’t get rid of them, and winds up sorry she ever opened the door as events progress.”
