One of my many attempts of editing the original spiderwalk scene from The Exorcist back into the film. I used outtake footage from "The Fear of God: 25 Years of The Exorcist" documentary. The music is called 'String Quartet' by Krzysztof Pendrecki, which can be found on The Exorcist CD soundtrack.
You can find the original un-edited outtake in the video response section below, along with a video of director William Friedkin and author William Peter Blatty discussing why it was cut from the film.
This version of the spiderwalk follows more closely to what William Peter Blatty wrote in the novel:
------------------------------
Chris looked up and froze.
Gliding spiderlike, rapidly, close behind Sharon, her body arched backward in a bow with her head almost touching her feet, was Regan, her tongue flicking quickly in and out of her mouth while she hissed sibilantly like a serpent.
"Sharon?" Chris said numbly, still staring at Regan.
Sharon stopped. So did Regan. Sharon turned and saw nothing. And then screamed as she felt Regan's tongue snaking out at her ankle.
Chris whitened. "Call that doctor and get him out of bed! Get him now!"
Wherever Sharon moved, Regan would follow.
