In an interview with Yahoo Entertainment at San Diego Comic-Con, Hardy recounted how he had his own paranormal experience while filming on location in a Transylvanian fortress. Hardy was shooting a sequence called the Corridor of Crosses with star Taissa Farmiga, and said he had set up his monitors in “this little cell room along the sides of this long corridor.

“As I stepped into the room I saw a couple guys sitting in [the back] of the room,” Hardy said. “I presumed they [were from] the sound department. I said, ‘Hi,’ and I quickly turned around — I had my back to them. And I was watching the monitors, I was watching Taissa, I was watching the camera, and it was quite a difficult scene to coordinate, and it took about half an hour.

“So I was sitting there, there’s only one doorway in and out of this room, and we finally got the shot. I turned around to say, ‘Oh, did you see that? What did you think?’ And there’s no one in the room. And there never had been.”

The Nun is slated for release in theaters on September 7th, 2018.
