Sad to say, it is apparently lost: a few years back I wrote to Alexandra and she replied that the movie is considered lost. Mind you, she used to work for the Paley Center when it was the Museum of TV & Radio, so she must have tried to find a copy of the tape or a kinescope. And it's a shame when you consider it was written by no less than Rod Serling! Perhaps someone can do a remake as the script still exists among Serling's papers. Amazing that a major production from a date as late as 1968 (and in color!) hasn't been preserved. But then, look at the horrid state of affairs with the BBC and how they have spent the past 20 years trying to recover stuff they erased or junked- far worse than the US networks!
