Of course, William Schallert ("Tribbles") was a recurring character on the show as teacher Mr. Pomfritt
Pomfritt?? Seriously?? They had a character named "Mr. French Fry"??!!
Personal thanks to Harvey for making it possible for me to see Dobie again after more than 50 years. I was 8 when it first aired.
My exposure to Dobie was limited. I'm not sure I've seen it at all since "Bring Me The Head of Dobie Gillis" ... which I turned off before it was over — fortunately.
We've covered TV and movies, how about radio? The fifth episode of the 1950 science fiction anthology Dimension X, adapting "Knock" by Fredric Brown (author of the story on which "Arena" was indirectly based), featured Arnold Moss (Karidian/Kodos) in the lead role, playing opposite Joan Alexander, the voice of Lois Lane in the '40s Superman radio series and cartoon shorts.
Ah, I know the original well. From memory:
The last man on Earth sat in a chair. There was a knock at the door.
"Hel-lo, Wal-ter."
(Edit: So much for memory. It's "sat alone in a room.")
