Last week I got Season 1 of Adventures of Superman
, starring George Reeves. It's black and white, released around 1952 or 1953. In "The Runaway Robot", I recognized John Harmon as a two-bit crook. He was the Rodent who kills himself with McCoy's phaser in TOS: The City on the Edge of Forever, and Tepo in TOS: A Piece of the Action.
This episode starred Russell Johnson as the boss bad guy. Johnson was veteran of science fiction films during the 50s and 60s, but most famous as The Professor on Gilligan's Island
. Apparently he wanted to do Star Trek, but never got a chance.
