The following also appears at The Land of Whatever.
Several years ago, I acquired the rarely seen 1961 pilot for The Adventures of Superboy, Whitney Ellsworth's last live-action adaptation of the Superman franchise. Coming three years after Adventures of Superman, one would think that one of the networks could've picked this up as a Saturday morning entry, five years before Superman would return as an animated cartoon.
You might recognize one of the villains in this story. It's Stacy Harris, who was a frequent guest star on both versions of Dragnet. Yes, the plot is right out of the same cookie cutter as the Superman series. No originality might explain why this wasn't picked up, but, to be fair, just judge for yourselves.
Edit, 11/13/15: Unfortunately, we can only provide a small sample:
At least this was better than Ellsworth's Superpup pilot.........!
