Fifties TV series that I watched as a kid:
Circus Boy (starring a little blond kid named Mickey Dolenz)
Casey Jones
Cannonball (about two truckers)
Jet Jackson (which I'm told was actually Captain Midnight reruns)
Anybody remember any of those?
I would have included Robin Hood in the list, but a few years ago, late at night, I saw a movie that someone cobbled together out of a few episodes of that show. It was fun, but the plots were too thin for anyone over the age of ten.
It's interesting to hear that there was a movie made of The Silver Sword. I read the book as a kid.
