If you sit next to Jared Harris watching a horror movie -- like, say, "The Quiet Ones" -- in the theater, be prepared for a little yelling. The "Mad Men" star plus "Quiet Ones" co-leads Sam Claflin and Olivia Cooke answered HitFix's question: What kind of a horror film audience member are you?

To get into the head-space of their own characters, they each tapped into their own experiences and personalities for the role: Cooke, who plays a disturbed mental patient Jane, may surprise you with her answer.

Meanwhile, Harris said how going to an all-boys Catholic boarding school brought out a little exorcism excitement in him.

Watch the full interview above with Harris, horror fan Cooke ("The Signal," "Bates Motel") and Claflin ("The Hunger Games: Mockingjay").

"The Quiet Ones" went to theaters on Friday (April 25).
