10 Horror Movies With No Obvious Villain

10. Devil (2010)

Claustrophobic thriller Devil is the perfect premise for a whodunnit-style horror where anyone could be the killer.

Set within the confides of a cramped lift, John Erick Dowdle’s flick sees a group of strangers find themselves trapped together when the lift they're in mysteriously breaks down. Being stuck in a lift is enough to ruin anyone’s day, but things are made much worse when one of the strangers is the literal devil.

Whenever the lights go out, one of the trapped is killed. Meanwhile, a small team of security guards and investigating police officers work to figure out what’s going on and discover who the killer is before everyone is killed. It’s a race against the clock to find answers while the bodies start piling up.

Executed with an endearing B-Movie charm that has all the idiosyncrasies M. Night Shyamalan (who’s credited with conceiving the story) is famous for, there are enough red herrings thrown in throughout its snappy eighty-minute runtime to keep viewers second guessing themselves to who the devil in disguise is.

And, coming from the mind of the Shyamalan, nobody will see the reveal coming when it’s time to unmask the true villain.
