Tom Felton, who portrays Ben's (Sebastian Stan) college friend, Patrick, a paranormal expert, was also drawn to the premise. "It's not a random cabin in the middle of the woods," Felton says. "It's based on something which people can relate to: an ordinary life, an ordinary day, an ordinary house."

Tom Felton says that the role of Patrick was an appealing challenge. "It's way out of my comfort zone. It was nothing like what I'd done before."

Lincoln notes, "I wanted to cast a younger, savvy guy with an edge as the scientific expert. Tom is an interesting actor and I'm excited for people to see him in this very different role."

Tom Felton recalls seeing ''ghost consultant" on the crew list and wondering, "What the hell is that?" The consultant was, in fact, real-life ghost hunter Joshua Warren, who was enlisted to lend his expertise. Felton reveals, "The research freaked me out to the point where when we came on set for the opening segment, I wanted to make sure all the machines were turned off during shooting our 'experiment.' I was convinced we were actually going to create something out of nothing. Joshua made it all so real."
