Aside from its main animation facility in Glendale, California, Disney opened a satellite feature animation facility during the production of Mermaid near Orlando, Florida, within the still-unfinished Disney-MGM Studios Theme Park at Walt Disney World. Though the park opened to the public a year later, work at the animation studio began in May 1988, and the Disney-MGM facility's first projects were to produce an entire "Roger Rabbit" cartoon short, and contribute ink and paint support to Mermaid.
