When the moving pendulum blade drops toward Malloy's throat, it is much closer in the close-up shots than it is in the longer shots (where Leslie's Nielsen safety would be a concern).
At some points, it is clear that under his eye patch Leslie Nielsen still has an eye. Look for it especially during the scene in which he is lying on the bed--the angle allows you to see right under the side of the eye patch!
Host: Time again for your weekly excursion into the cultural. Paintings, statuary, still lifes, collages, some abstracts, and some items in ice. That's not the technique. That, hopefully, is what we turn your blood into. A good way to begin the attempt, painting number one, about a man who spends a night in a haunted house. An unbeliever, if you will, who, by dawn, believes. The name of the painting is A Question of Fear. The name of this place is the Night Gallery.
Malloy: Interesting color, white. I've often wondered why they call cowards yellow, when it's the white flag they use to surrender.
Mazi: Recently, my colleague and I discovered a way of converting a complex enzyme molecule in the human body until its structure is identical with that of an annelid. Better known to you as an earthworm.
Malloy: That's terrific, I'm delighted for you.
Mazi: The result is quite extraordinary . The bones of the body disintegrate without affecting the nervous system or the vital organs until the victim is, as near as can be, an earthworm.
Malloy: You're out of your mind, man, that's impossible.
Mazi: Really? Then I suggest you pay another visit to the cellar. There you will see now my colleague. He's quite harmless - only rather repulsive.
This episode is based on the short story "A Question of Fear" by Bryan Lewis.
