Dailies | Eric Bana Couldn’t Sleep After Watching Exorcism Videos for ‘Deliver Us From Evil’ (Video)

The horror film is based on the paranormal investigations of retired NYPD veteran Ralph Sarchie, who became a demonologist

Eric Bana takes on the real-life role of retired NYPD officer Ralph Sarchie for his latest film, “Deliver Us From Evil.” In preparing for the role, he saw actual footage of Sarchie assisting in exorcisms in New York, admitting on “Chelsea Lately” that they kind of freaked him out.

“In pre-production we saw some video tapes of of [Ralph Sarchie] which I really wish I hadn’t seen,” he told Chelsea Handler. He added that they “sort of jolted my safe skepticism.”

When Handler asked if he had trouble sleeping afterward, Bana admitted that he did for about a week. “The thing about it is it wasn’t what you expect,” he explained. “You’re expecting someone making a lot of noise and kind of screaming and ranting and yelling and it’s not that at all. It’s a really still kind of really eerie thing. And it freaked me out.”

Bana channeled that into his performance as Sarchie in “Deliver Us From Evil,” which co-stars Edgar Ramirez as the priest he partners with on exorcisms, as well as Olivia Munn, Sean Harris and Joel McHale.
