The person was originally intended to be Larry, whom Kirsty was going
to find, and rescue from Hell. As this bit was unfilmed, the viewer
is led to believe that the person was actually Frank, impersonating
Larry, and tricking Kirsty into go to Hell.
Do Kirsty and Kyle hit it off?
Yes, in the original script they do. But this was never filmed.
Kirsty was to actually spends the night at Kyle's place, and
kiss him in a certain scene.
Chatterer and Chatterer II - what's the difference?
An unfilmed part in the corridors of Hell, shows Chatterer in Hell's
equivalent of a beauty salon, being re-made. This involves the scar
tissue being manually peeled from the upper part of his face to reveal
small, vicious, human eyes. The differences are noticeable though:
Chatterer (Hellraiser) : no ears, hooks around cheeks.
Chatterer II (Hellbound) : ears, no hooks around cheeks.
