The Quiet Ones, based on a true story, takes audiences on a terrifying journey into one scientist’s effort to create a poltergeist and in the process rid the world of all those supernatural scares.

It stars Jared Harris (Sherlock Holmes: Book of Shadows) as the professor and he is joined in the effort by Sam Claflin, who plays the filmmaker charged with chronicling the experiment, and Olivia Cooke as Jane -- the woman who appears to be possessed by an entity named Evie.

We caught up with Harris, Claflin and Cooke and in light of all the success horror movies have had over the years, we wondered if they -- after starring in one -- had any idea why it is that with so much real fear out in the world, we as an audience voluntarily head into the dark to be terrified.

“You’re in a safe environment,” Cooke said. 

“It’s safe danger,” Claflin added and laughed.
