'Killer Kane' - origin of the name?
I wonder if William Peter Blatty ever watched the 1968 western, More Dead than Alive, starring Clint Walker and Vincent Price.
Clint Walker's character, a gunfighter who is released from prison after serving eighteen years for multiple murders, is named "Killer Cain."
Different spelling, but pronounced the same as Stacy Keach's character.
Thoughts?
