"The Black Cauldron" is notable for being Disney's first animated feature film to incorporate computer-generated imagery in its animation for bubbles, a boat, a floating orb of light, and the cauldron itself. Though "The Black Cauldron" was released a year before "The Great Mouse Detective", both films were in production simultaneously for some time and the computer graphics for the latter were done first. When producer Joe Hale heard about what was being done, the possibilities made him excited and he made the crew from "The Great Mouse Detective" project create some computer animation for his own movie. For other effects, animator Don Paul used live action footage of dry ice mists to create the steam and smoke coming out of the cauldron.
