McLendon became even more famous in the 1950s when he bought some radio stations in Texas. The ones I listened to were KLIF in Dallas, KTSA in San Antonio, and KILT in Houston. On a good day, I could pick up all three of them in a car radio in Mexia, Texas. He might not have invented the Top 40 format, but he was expert at exploiting it.
At some point in the late '50s, McClendon got the idea he wanted to be a movie producer. Ken Curtis (best known as Festus on Gunsmoke's TV incarnation) went in with him, and one of the movies they produced was The Killer Shrews. Some would say that this movie makes Plan Nine from Outer Space look like a big-budget Hollywood studio production. If you've seen it on MST3K, you know what I'm talking about. Or scroll down and take a look at the trailer.
The special effects for the killer shrews drew the most laughter in the theaters in the '50s (yes, I was there). They were obviously just dogs with some tacky fur glued on them. The plot is ludicrous. A mad scientist is trying to shrink people to about half their normal size in order to cure world hunger. Somehow his formula creates killer shrews, and the cast is trapped on an island with them. Several people fall victim to the shrews, but the others escape in . . . you need to see it.
This is a classic of its kind, and it was filmed in Texas!
