...but I wouldn't mind reading a prequel novel about the death of Lionheart's wife. Perhaps the events of "Theatre..." wasn't the first time he's gone on a rampage?
Now put that gun down Heidi! You’re not solving anything by massacring people!
I wouldn't want to see a sequel either.
"There will be blood. Oh, yes! There will be blood."-Jigsaw; "Saw II"
Nah, that'd cover the same ground as The Abominable Dr. Phibes, plus Vincent Price wouldn't be around to play Lionheart!
On an unrelated note, Tim Burton wants to remake The Abominable Dr. Phibes. Or perhaps it was that he wanted to do one of the sequels that Bob Fuest had written a script for but wasn't able to get produced. At any rate, I think that could be a fun project if Burton could dial back the CGI he's been so obsessed with for the past decade or so.
