Trivia

First Disney animated movie to be spun off from a television series.

This was the first Walt Disney film released to theaters that was animated, not by the Disney "Feature Animation" division, but by the "Television Animation" division. This explains the notable difference in quality between this film and other Disney animated releases around the same time (for example, The Little Mermaid (1989), The Rescuers Down Under (1990), and Beauty and the Beast (1991)). The Television Animation division has since produced several other theatrical releases, such as A Goofy Movie (1995) and Return to Never Land (2002) (with striking improvements in animation quality), as well as numerous direct-to-video sequels for Disney features.

Alan Young used to joke that given the treasure hunting story, that this movie would be the closest he'd get to playing Indiana Jones.

There were originally plans to have films based on Chip 'n' Dale Rescue Rangers (1989) and Goof Troop (1992) following this film. However, after the film performed below expectations at the box office, the "Chip 'n' Dale" film was scrapped and the "Goof Troop" movie was re-purposed as a standalone follow-up to the series, titled A Goofy Movie (1995). A "Chip 'n' Dale movie would eventually be produced in 2022.

Side characters from DuckTales (1987), like Gyro, Doofus, Bubba the Cave Duck, and Gismoduck are absent, as the filmmakers didn't want to confuse newcomers who have not seen the Disney Afternoon cartoon. This is also why none of any of the show's villains, like the Beagle Boys, Magica DeSpell, and Flintheart Glomgold are present.
