This was Kirstie Alley's only Disney movie.
The first Disney Channel movie to be rated PG and to have foul language.
Was the last movie that Kathryn Zaremba did. After "Toothless" finished shooting Kathryn Zaremba retired from acting.
Limbo is actually set in a very famous location called "Vasquez Rocks" where many television shows and movies have been filmed. One of the most famous is the original Star Trek series show called "Arena" where Captain Kirk fights the Gorn. This shot was then recreated in the movie "Paul" with Simon Pegg and Nick Frost.
Kristie Alley's character is the only Tooth Fairy who doesn't have wings.
