[neverending]

I haven't seen Jason Goes to Hell (is it anything like Ernest Goes to Jail?) but the necronomicon was not created for the Evil Dead. It was created by H.P. Lovecraft in his stories. The name "Necronomicon" has become such a part of the horror lexicon I doubt you have to ask anyone to use the word. Nevertheless, you wouldn't have to ask Sam Raimi for permission to use Lovecraft's term.
