"WORLD OF GIANTS" 101 Special Agent, 1959 Television

Years ago, I did Web a search for all 13 episodes of this science-fiction espionage Television series.
This is the only episode that I found on the web.

My brother, and I, watched all 13 episodes in 1959. It never appeared on Televison again.
I was surprised to see on the Wiki episode list that two very talented directors Jack Arnold and Byron Haskin directed episodes.
