Random Trivia For This Title:
- During production, director Don Bluth staged a demonstration of the difference between limited TV animation and the full animation used in the film. He had his staff stack up animation cels by his feet into two piles, one representing two minutes of limited animation, the other two minutes of full animation. The TV pile reached only to Bluth's shoelaces; the film pile went all the way up to eye level.
- A shot of a cat lunging towards the camera during the market attack is recycled from Don Bluth's previous film, The Secret of NIMH.
