I think that AMC’s show “James Cameron’s Story of Science Fiction” used DE as a source for their theatrical shots.

Discussing it over in that thread, but I think it’s possibly not from 2.7. Either from another TN1 release (one that’s better quality than the original release I used), or another high quality scan?
