The late Trio cable channel had a series called “Brilliant But Canceled” about shows on TV all too briefly:
I wouldn’t call what follows “brilliant,” but they were definitely canceled, and shortly after I started watching them at a very young age.
“The Interns,” which was on briefly in 1970, includes an actor from “Star Trek” and “The FBI,” another “Star Trek” actor, B.J. from “M*A*S*H,” one of those actors whose face you recognized (before his untimely death at 49), and the star of “Highway Patrol” in a series that lasted one season:
Before I knew Glenn Ford as a movie actor of long standing, I saw him in this one-season series:
My viewing preferences of TV series with cars probably started with the 13-episode “Bearcats!”
Perhaps because of his recently canceled “Get Smart,” I watched the next sitcom of Don Adams, “The Partners.” The only episode I recall was when their car’s driver’s side door was sheared off by a passing car, creating a three-door detective car.
“Partners” was moved halfway into its only season. Its time-slot replacement was “Emergency!”
You’ve already read here about “Chase,” produced by Jack Webb;
Another Webb series not long for the screen was “Project UFO”:
Movie fans may remember an actor named Khigh Dhiegh, the Chinese bad guy in “The Manchurian Candidate.” TV fans remember him (name at birth, believe it or don’t: Kenneth Dickerson) as Wo Fat in the original “Hawaii Five-O.” While playing Wo Fat, Dheigh briefly was the lead of “Khan,” about a San Francisco private detective. “Khan” is so rare that you can’t even find a snippet of it on YouTube, perhaps because it was canceled two episodes into its four-episode run.
As you know, quality and popularity are not synonyms. I don’t remember much about any of these series, but since none lasted very long, neither does anyone else.
