It worries the moguls, of course, because what happens to the movie if Lee disappears for some reason when it's only half complete. It will be a different location every night, unknown to anyone else. He barely escapes but insists that from now on, he himself will decide where to live. Then there is a genuine attempt on somebody's part to murder Lee. The studio pooh poohs this as superstition but they assign a studio cop to be constantly at his side. They pursue you, subject you to a painful and lingering death, and then mutilate your body. You don't defect from the First Amalgamated Zionist Church of Beelzebub and get away with it. Lee shows up when summoned but he's a little nervous.
They decide to make a movie about the cult and import Lee to star in it. Lee is the Bishop, or the anti-Bishop or whatever, and the moguls are enthralled by his performance. A handful of Hollywood producers and other high-echelon types are watching a film of a Black Mass that was conducted in Europe somewhere.
I think we can all agree that the worship of Satan is a bad idea, but it's even worse being a lapsed Satanist, as Christopher Lee can tell you.
