There's a new horror movie on the way called Mara, and we've got an exclusive clip from the film that's almost sure to have you watching the foot of your bed tonight.
The movie stars Olga Kurylenko (Oblivion) as Kate Fuller, a criminal psychologist who is investigating the death of a man who was apparently strangled in his bed. When Fuller questions the man's 8-year-old daughter, all she can get out of her is the name "Mara."
Further digging on Kate's part reveals the existence of an entire community of people who claim to be the prey of a shadowy, ancient demon that kills people while they sleep — and paralyzes them beforehand.
Director Clive Tonge apparently based the movie on the real-life phenomenon of sleep paralysis, during which people are conscious but unable to move as they are either falling asleep or waking up. The sensation is sometimes accompanied by sounds like roaring, hissing, or even voices, as well as hallucinations of other figures in the room around or above them.
The creature in the clip is played by Javier Botet, whose resume includes other frightening apparitions such as the Leper in Stephen King's It, the title roles in Mama and Slender Man, and other entities in movies like Insidious: The Last Key, Crimson Peak, and The Conjuring 2.
