Been watching
Tales of Tomorrow, the first SF anthology show on US television. (1951-53)
Half hour vignettes, filmed in Black and White with little or no refilming or editing. YouTube has them complete with period ads.
Not made for kids and developed with the Science Fiction League of America. Stories by Theodore Sturgeon, Kornbluth, Weinbaum, Verne, VanVogt, Padgett (Kuttner & Moore), John Cambell and numerous other authors from the Golden and Silver ages of SF/Fantasy.
The Little Black Bag, What You Need, The Crystal Egg, Frankenstein, 20,000 Leagues - - - and many more.
Actors included Boris Karloff, Paul Newman, Lee J. Cobb, Rod Steiger, James Dean, Franchot Tone, Thomas Mitchell, Burgess Meredith, Raymond Burr, Jackie Cooper, Jack Warden, Jack Carter, Leslie Nielsen (five episodes), Darren McGavin Nina Foch, Mercedes MCcambridge, Eva Gabor, Una O'Connor, Cloris Leachman, Sylvia Sidney, and Joanne Woodward.
I found it amusing that a few actors are prominently mentioned in descriptions but are so minor that if you blink you'll miss them (Newman).
All produced pretty melodramatically, but actually fun to watch as drama, beyond enjoying as history.
A few got re-filmed for
The Twilight Zone.
On YouTube, I put in either "Tales of Tomorrow Complete episode" or Tales - - - with the name of an actor.
Here's the Wikipedia with the list of 85 episodes.
