I’m not sure if I’ve seen this before, if it’s on one of the already released DVDs or Blu-rays or if it will even be on the forthcoming The Exorcist (Extended Director’s Cut) Blu-ray hitting shelves on October 5. The features are multiple, but there’s no specific mention of this cool little video.
Just below is a look at scenes from The Exorcist featuring Linda Blair‘s original audio followed by the same scenes with the voice of the demon as provided by Mercedes McCambridge.
From a 2004 article at the New York Times:
Because of her great vocal skills, Ms. McCambridge was hired to portray the Demon in William Friedkin’s 1973 smash hit The Exorcist. After weeks of what she called the hardest work she had done for a film, she was promised prominent mention in the credits.
But when she attended the preview, her name was missing. As she left the theater in tears, Mr. Friedkin tried to explain that there had been no time to insert her credit. The Screen Actors Guild intervened and forced her inclusion.
Watch the video below, it’s almost just as creepy before the voice effects were applied as it is after.
