In the early 60's it was as science fiction series introduced by Boris Karloff on Saturday nights on ITV. Causing a few arguments amongst us veterans! TIA.
This reminds me of a time about 8 years ago when I was trying to recall a series I saw many years previously. Hoped to be able to get to see some episodes or whatever. Took me ages to find out it was "Out Of The Unknown" and the BBC had destroyed the series. Just a few episodes have been found since :-(
