Alternate titles
When "The Ninth Configuration" hit theaters on the East Coast U.S. in the summer of 1980, it had the title "Twinkle Twinkle Killer Kane." It was also the title of Blatty's novel when it was originally published.
Two points to make here:
1. Changing titles may have hurt this film in finding an audience when it was originally released.
2. "Twinkle Twinkle Killer Kane," strange as it is, worked better as a title than "The Ninth Configuration," the former title having an air of mystery and beauty whereas the latter sounds like something out of a recipe book. Am I the only one who thinks this?
