Sometime during the 1980s or early 1990s, when I had money and could afford cable, I stopped on the public access channel because I saw what looked like TOS Star Trek, but really wasn't. It may have been during the lean years, before TNG showed up.
The audio was directly from the episode "The Doomsday Machine", but the footage looked like it had been done on Super 8mm or 16mm color filmstock, with amateur actors in passable uniforms and rather simple sets. They pantomimed every single scene to the soundtrack. The whole thing was like a serious reconstruction of the episode, not played for laughs. I don't remember if they used original effects clips or made their own. I only saw it once, though I checked through the week to see if it would show up again. It was a very surreal experience.
Does anyone else remember seeing something like this? It could have aired in Chicago, Phoenix, San Francisco, or St. Louis given the approximate dates.
I think the same group later did a non Trek film called Captain Future.
