Keeper of the Purple Twilight

The Outer Limits (1963)

Keeper of the Purple Twilight, directed by Charles Haas.

In advance of the invasion of Earth, an alien wants to know what all this "emotions" stuff is about, particularly that "love" weirdness that no one can explain. He swaps some mentality with a human scientist in exchange for the secret of a disintegrator beam (an odd thing to trade prior to war) and spends time with the human wife to work out the "love" details.

As you might expect, this interferes with the invasion plans.

Another SF action/thriller, modest in both dimensions. So much of the time is wasted filler.

Great title. No one knows what it means. The plot reminds me some other cheezy SF film, but I can't bring it to mind.

The alien rubber head is pretty impressive. I believe it was the last costume done by the great Wah Chang for the series.

The cast:

The Blu-ray commentary track is by David J. Schow. Claiming there is not much to say about this episode (although he does anyway) he spends a lot of time on season 2 as a whole, its many problems.

Admittedly this is not a strong episode, but he speaks of it as one of the worst: kiddie-SF derived from pulp magazines and matinee serials. I wish.
