NOVA ran a modified version of the doc. The above link is an interview with the producer. The official PBS store used to sell copies.

So NOVA ran this on TV? And there were copies available for sale? What format - VHS, DVD? And did anyone buy a copy?

If such a copy was available, this screams preservation, folks.

About a third (most of the Star Wars related material) was previewed at a convention back in 96.. A preservation of that is available on TWC301:

Very nice...at least we can now review what was in the film!
