Hawaii-born cast members Jason Scott Lee and Tia Carrere helped the writers with dialog and accents.
Disney promoted this movie with a series of trailers inserting Stitch into some of its "classic" titles. Examples:
- The Little Mermaid (1989): Stitch surfs a wave that crashes down on Ariel.
- Beauty and the Beast (1991): Stitch causes the chandelier to fall during the ballroom scene, nearly smashing Belle and the Beast
- Aladdin (1992): Stitch steals Princess Jasmine from Aladdin during the "A Whole New World" magic carpet ride.
- The Lion King (1994): Stitch takes Simba's place on Pride Rock during the "Circle of Life" opening.
One of the most complex parts of Stitch's characterization is that it's challenging to read what kind of emotion he is feeling, mainly because his eyes don't have pupils. The animators essentially got around this problem by making Stitch very physical.
"Lilo" means "generous one" and originates in Hawaiian. It can also be interpreted as "lost," and this would give the song title "He Mele No Lilo" a loose translation as "Lullaby of the Lost." The name Nani means "Beautiful" in Hawaiian.
Like the live-action monster movie that appears briefly, photographs of Elvis Presley are real pictures and not animated drawings.
