Ama and the Mysterious Crystal/Trivia

Trivia

 * This is Universal Studios' first animated film that was created completely in-house, as Steven Spielberg's Amblimation's films were distributed, but not produced by Universal, and An American Tail (1986) and The Land Before Time (1988) were produced by Don Bluth's American-Irish Sullivan Bluth Studios.
 * This is Universal Animation Studios' first traditionally animated film.
 * This is the first Universal Animation Studios film to be released in December.
 * Coincidentally, this film was released on the same day as the dark comedy film Mouse Hunt, which happens to be the first family film from DreamWorks.
 * THX was chosen by Universal Studios Home Video to digitally remaster the film on both VHS & Laserdisc. However, THX digitally remastered the widescreen VHS of the film instead, allowing it to improve the image and sound quality for the widescreen version. Nevertheless, THX digitally remastered both the Signature Collection and DTS Digital Surround Laserdisc releases and later the 2000 DVD release.
 * It is also the first Universal Animation Studios film to be digitally mastered by THX on home media releases.
 * Karey Kirkpatrick and Michael J. Wilson did an uncredited rewrite of the script.
