With a hunched-over body, Coke bottle glasses, and a name like "Crangle", you know weirdo is going to follow. And it does, in spades. The half-hour really amounts to a Bikel showcase, as he gets to go through about every loony tune in the weirdo song book. As Crangle, he's out to eradicate the world of evil, that is, evil according to his own expansive definition. His poison is to contact folks "harboring" evil ones and let them know what they're doing. Needless to say, his lunacy is damaging a lot of undeserving victims. Yet he gloats the gloat of the smugly righteous. So what will happen at 4-o'clock when he "wills" the world's evil people to shrink down to midgets. That's the question.
The production's a one room, small cast setup that frankly features Bikel's same lunatic note the whole time. The only real interest is what Serling's got in store when the clock strikes 4. Otherwise, there's little storyline except for the loony emoting. I wish the screenplay provided a bit of Crangle's background. As it is, he and his venom are just sort of dropped in. To me, it's a mediocre entry at best.
(In passing--that's Moyna MacGill, Angela Lansbury's mom, as the aging woman. It's striking, to me, the family resemblance between the two.)
