Has anybody seen this?

Other than the brief clip played on brilliant the THX 1138 DVD documentary ("A Legacy of Filmmakers: The Early Years of American Zoetrope"), the single-paragraph review found on this site is the only thing I've been able to dig up on this.

Does anyone know how you could go about seeing it? I imagine it would make for a fantastic addition to the THE RAIN PEOPLE DVD that will probably never see the light of day.

Is it available at the USC/UCLA film library? If anoyne has anything to share about this rare documentary, this Coppola/Lucas fan would surely appreciate it. Cheers!
