Re: The Black Cauldron - The Film and the DVD **Warning Complete Story Spoilers**
The Black Hole was in development for a long time at Disney, several years before Star Wars even.There was once a great fan site devoted to the film that had images of all sort of pre-production artwork. Many of them were dated pre-1977. Vincent was more mechanical and not cute in those. Obviously Star Wars was the catalyst that finally got the film into production.
I loved it when Sealab 2021 had a robot that looked a lot like Vincent tormenting Captain Murphy!
