Blumhouse has a couple of movies filmed and undergoing test-screening / planned for release this film:
"You Should Have Left," directed by veteran screenwriter David Koep. It's based on a German horror book about a writer that goes into the German alps to finish his screenplay before realizing that he may be losing his mind, or the house is changing around him. It's a terrifying book and it has had test-screenings (two in LA, maybe some others elsewhere) already, so I'm guessing it'll see a theatrical release some time this year or next year (December? October?)
"The Hunt," directed by Homestar Runner creator Craig Zobel and written by David Lindelof. It's an "action horror" that, according to collider, revolves around, quote, “a group of ‘rednecks’ who are captured and hunted for sport by rich, liberal elites.” So Battle Royale crossed with The Purge but for the other guys. It could be a hit, it could be a disaster, who knows given the current climate; that having been said, it's something to look at, especially depending on how well it does at the box office and whether or not it gets a sequel
"Prey," directed by Franck Khalfoun. It's a high school teen thriller, something terrible is happening, it was filmed back in 2016 and I have no idea what's going on with it. Wikipedia lists Uni as the distributor though, so I'll just list it for now.
Magic 8 Ball got announced this past week, so it's probably not gonna see the light of day for the next year or two.
