The eleven-footer at Film Effects of Hollywood.
The days of large-scale miniatures: the above picture is a sample bluescreen shot from a television series called Star Trek. Linwood Dunn's company, with Dunn himself behind the camera, photographed lots of "beauty-pass" material of the USS Enterprise, including this original footage for the first season episode "Space Seed". (The Howard Anderson Company had the model for the two pilot shows and the first few episodes, before it was shipped to Dunn.)
That's enough Trek postings for a while. I've done a few in the last few weeks to celebrate the stellar show's premiere fifty-five years ago.
Back down to Earth, and 2021....
