I noticed actor Charles Dierkop played the role of "Pete Royster" in this series.
He has been in a lot of stuff, but I immediately knew his name as the uncredited "Horned Mutant" in S1.E13 of LOST IN SPACE, entitled "One of Our Dogs is Missing."
As a matter of fact, we just lost Mr. Dierkop this year, back on Sunday, February 25. He was 87.
