I'd forgotten that the Martian Chronicles came out as a TV mini-series -- they were fantastic stories to read and I thought that (for the time) the TV interpretation was very well done indeed...
...I don;t think we got the Ray Bradbury theater in the UK (but I might be wrong on that)
Did we actually get through like a hundred comments without mention of "The Martian Chronicles" TV series and "Ray Bradbury Theater"? They were 80's TV, but that was so long ago that it seems close enough to me.
One series I liked as a young boy that I don't think ever made it to the US was "Adam Adamant Lives!" I don't believe that there was much science fiction in it apart from the McGuffin that set up the series, though.
The main character was a victorian "gentleman adventurer" who was trapped and frozen in a basement by his Moriarty-like nemesis. He was unfrozen in the 1960s when the building in which he was trapped was demolished.
@OmegaMan: Re your comment "Starship Troopers has been made into a movie... also The Puppet Masters? I would like to see "Tunnel in the Sky" made into a movie."
"Starship Troopers" was a wonderful book, but the movie was dreadful -- it didn't address any of the political issues in the book at all.
"The Puppet Masters" was an OK film for its time, but it could stand being remade with modern effects and technologies.
"Tunnel in the Sky" would make a WONDERFUL film, as would "Time for the Stars," "Red Planet", "Between Planets", and "Farmer in the Sky" (to name but a few)...
Starship Troopers has been made into a movie... also The Puppet Masters? I would like to see "Tunnel in the Sky" made into a movie. A group of young people are dropped off on an unknown world for survival testing... but are never picked up, and have to fend for themselves.
