I got in contact with UCLA and they gave me some details on how to possibly access their video. They want me to contact DIC Enterprises since they hold the rights, but they're now a part of DHX Media, so I'm not sure who to contact.
Update on my progress: I had two contacts at UCLA who would have been able to access the tape. I did some extensive film work for 1 of my contacts (as a favor if he helped me), but in the end he was not willing to help me get the tape as it required some footwork on his end. The other contact was more or less the same. So as of now i've exhausted my current resources.
Has anyone tried to contact the actors who played King Koopa they may have more info on it but thy are unlikely to respond
Cris Latta has passed and Pat Pinney has not been contacted. We need to appoint a liason for contact. Then the contact info will be available to the liason and myself, as we need to respect people's privacy. Any contact info should be posted in the discord and then the info will be placed in a spreadsheet shared only with myself and the liason, with the original post being promptly deleted.
Without archival, humanity would be lost to the sands of time.
