Lost in Space and Star Trek share something in common, in 1964 both series had their pilot episodes rejected by network broadcasters but were given a second chance if recommended revisions were made. For Lost in Space, this gave 20th Century-Fox an opportunity to replace the large 4ft. diameter "Gemini 12" spaceship with a smaller scale "Jupiter 2" that included onboard running lights. One of the issues with the large-scale model was the way it never appeared to have the same shape depending on the backdrop, lighting, or broadcasting filters used in post-production. That the Gemini 12 looked different shapes, scene to scene, remains one of the strangest optical effects no one could adjust for!
Lost in Space became the most heavily promoted TV show on CBS for 1965. That summer, no one could escape the image of the Jupiter 2 heading for a crash on an alien planet as CBS ran promos all day, everyday. Filmed and broadcast in black & white added to the show's "spaciness", in my opinion.
Episode One drew a huge audience as viewers wanted to see the entire crash scene. That the Jupiter 2 didn't crash in Episode One caused a spillover effect for Episode Two.
I'll never forget the excitement in the air as the end of Episode Two hinted at the "Crash to Come" in Episode Three. The final two minutes at the end of Episode Two show the only remaining footage of the original spaceship. Note the lack of operational lights on the model and how the poor quality YouTube upload completely washes-out all visual details of the Gemini 12. Apologies for the poor audio quality too. You may need to boost the volume to hear anything!
I was 8 years old when I first saw this.
