The Galaxy Being, written and directed by Leslie Stevens.
A devoted radio engineer develops 3D television and tunes into microwave broadcasts from another galaxy. Inadvertently: it is also a matter transmitter. He has already cobbled together an automatic language translator. When an irresponsible DJ turns the power up too high, First Contact follows.
This is a fine pilot episode for the series. The alien effects are pretty simple superimposed negatives, but that nicely suggests a truly alien incompatible form of matter. The visitor looks like the surface of a star with sunspots.
As always, the sound and visual design of the program is superb. The music cues bring back so many memories, tying the whole series together.
The plot is a familiar one of obsessed scientist in tension with his wife and social obligations. See Altered States (1980) for another treatment. The clever bit this time is that the only like-minded friend our hero can find is a deathless "nitrogen-cycle" (?) being from Andromeda. Who is also a renegade, breaking the rules to contact other life.
The story pauses for a couple instances of TV drama-speak between husband and wife. We see the show is still rooted in the TV anthology genre of the 1950s, which itself had roots in radio serials of the decade before: often the same actors, same types of stories.
We have parallels to The Day the Earth Stood Still (1951): our fear of the alien, his healing powers, and his final lecture on the need for understanding.
Notes:
We're ignoring the speed of light in this clever scenario.
In a real-world parallel, early radio astronomy was indeed pioneered by amateur enthusiasts. Grote Reber built the first parabolic radio telescope in his backyard and did a complete sky survey. For ten years he was the only radio astronomer in the world.
The alien says that electromagnetic waves are the ultimate reality. There is no death because the brain waves travel outward forever.
The truly unbelievable part: army, police and mob disperse when dismissed by the alien.
The radio station silhouetted against the sky became a scene in my dreams.
I always loved the astronomical photos in the closing credits.
The commentary track is by Outer Limits expert and author David J Schow. He gives much background on Leslie Stevens and the origins of the series.
He notes the similarities to The Day the Earth Stood Still (1951)...
...and also that our engineer has found a like-minded companion from across space.
The brother's girlfriend is played by Allyson Ames, married to Leslie Stevens at the time.
William O. Douglas Jr is the man in the alien suit. He was the son of the Supreme Court justice of that name.
The suit was a neoprene wet-suit worn backwards and oiled to make it shine. The eyes were "crow's eyes", glass ones from a taxidermist, I presume.
