Remember the little girl in Poltergeist, transfixed by the ghostly voices coming through the TV set after the channel went off the air? That was EVP, or Electronic Voice Phenomenon, and it’s the paranormal premise of White Noise, Michael Keaton’s spooky new film coming to theatres Jan. 7. Supporters of EVP see it as a sort of high-tech update of the old seance or Ouija board, with the dearly departed using the electronic tools of our age to try to communicate with the living. Ironically, white noise — that video snow and audio rush between TV and FM frequencies — isn’t heard much in this age of cable TV and digital radio tuners. You’d have to go low tech — an old 12-channel TV set with rabbit ears, say — to experience pure white noise. Then you’d have to listen to, well, basically nothing but that random audio data for about 20 years before even fervent believers say you might actually hear and record something from “the other side.” As a supernatural experience, EVP has been seriously chronicled since about 1939, and Keaton feels White Noise is about to spark new interest in it. But he remains neither a believer nor non-believer. Interviewed during a recent promotional visit to Toronto, the actor, best known for playing Batman, swears he approached this film not wanting to be tainted by any supposed evidence. ‘It’s very intriguing’ “We purposely didn’t try it,” he says. “Who am I to say? I think it’s very intriguing, all this stuff.”
