Trivia: In the scene where Meg appears, Richard Picardo had a hard time breathing in the latex costume and mask while underwater. When he/she pops up, look closely; Meg appears to be spitting water and gasping for breath.
Trivia: The unicorn voices were the sounds of humpback whales.
Trivia: During the making of the film, the directors had real birds populate the forest set (one of the largest sets ever built for a movie). One day it was suddenly destroyed by an accidental fire. (No one was hurt, and all the birds flew out safely). They had to rebuild the entire set and continue filming.
Trivia: There is a persistent fan-theory that this film was one of the main inspirations for the iconic "Legend of Zelda" video-game franchise, though this has never been completely confirmed, and is up for debate as both the game and film were in production during the same time period, so it is unlikely that anyone involved in the game's production saw the film until only a few months before the game's release.
