Yes it was Frank Gorshin. I remember it well. A Favorite of mine was "All Our Yesterdays."I had already graduated from high school and was out on my own when it came out. I liked the 'Tribbles' episode, as well as 'Sharper than a Serpent's Tooth'. There was another, the title of which escapes me. It was about 2 races, both half black and half white. One was black on the left side, while the other was black on the right side, and they hated each other because of it. I believe that Frank Gorshin was in it, but I could be mistaken.
