9 scary movies you might have never seen that you can stream right now

Not all scary movies have to feature gore and evil killers. Sometimes the situation is horrific enough.

Take, for instance, this 2012 indie film.

Long before director Craig Zobel directed "Mare of Easttown" he made this movie based on "strip search phone scams" that went on in the early 2000s.

In the movie, like the real-life instances, someone calls a fast-food restaurant claiming to be a police officer, and then convinces the manager over the phone to conduct a strip search of a female employee.

Yes, everything in this movie happened in real life.

The movie stars Dreama Walker as the employee, Ann Dowd as the manager, and Pat Healy as the caller impersonating a police officer.

Okay, looking for gore and evil? Here you go.

Neil Marshall's 2005 horror follows a group of thrill-seeking women who set out to go caving. But they definitely chose the wrong cave. The group begins to be taken out by scary creatures living deep inside the cave.

The movie concludes with one of the best endings in a horror you'll probably ever see.

Speaking of a horror movie with a great ending.

This 1990 psychological thriller from director Adrian Lyne is a mind-tripping masterpiece.
