8 Horror Movies That Were Filmed In Total Secrecy

Making a movie takes a lot of time, money, and effort. Shocking information, right?

All sarcasm aside, a movie production is a huge undertaking. Actors, camera operators, lighting directors, sound engineers, whatever the hell a "Best Boy" is. They've all got to be in the same place at the same time playing their parts to perfection.

So how on Earth do you make a movie in secret? Let alone one with all the bloody excess of a horror.

Well, you should ask these lot. They figured it out.

The following eight films were all filmed in total secrecy, so imagine everyone's surprise when they were suddenly announced as done seemingly out of nowhere.

Some had marketing leading up to their release, whilst some literally just appeared one day and everyone was like, "Umm, ok, guess I'll see that then!"

From big name directors and actors to fairly humble staff members, these production crews deserve some sort of medal for how they managed to keep tight-lipped about such massive projects.

If any intelligence agencies are out there and in need of any camera people, then maybe give some of the folk on worked on these pictures a call. They know how to keep their mouths shut.

Steven Soderbergh is a very successful man, despite having a name that could very easily get him confused with Steven Spielberg.

The Academy Award winning director of Traffic, Logan Lucky, and the rebooted Ocean's series usually ranks pretty highly when discussing popular directors of the modern age. So imagine how excited his fans were when it was announced that he'd shot a film entirely in secret.

Unsane stars Claire Foy as a woman who has to leave her home city to avoid a stalker. She finds herself committed to a mental hospital and, once inside, she realises that the people working there aren't out to help her at all.

Also starring Joshua Temple, Juno Leonard, and Matt Damon, Unsane was very well-received amongst viewers. They praised the quality of the acting, the depth of the story, and the cinematography - which is mad considering the entire thing was shot on an iPhone 7 Plus.

This was a big risk for Soderbergh, who knew that any marketing surrounding a new release of his was sure to be successful. But the film made $14.3 million on a $1.5 million budget, so well done him.
