* Different metrics: Do we look at worldwide gross, domestic gross, or adjusted for inflation?
* Changes in Disney: The Disney company has undergone many mergers and acquisitions, so what counts as a "Disney movie" has evolved over time.
* Limited information: Box office data for older films isn't always readily available or accurate.
However, some contenders for the title of "lowest-grossing Disney movie" include:
* "The Black Hole" (1979): This sci-fi adventure film underperformed at the box office and is often cited as a financial disappointment for Disney.
* "The Gnome-Mobile" (1967): This live-action musical comedy based on a novel wasn't a box office hit.
* "The Love Bug" (1968): While a popular film, its original release was a modest success financially.
It's important to note that even a "low-grossing" film can be considered successful depending on its budget and other factors.
To get a more accurate answer, you'd need to consult specific box office data sources and define your criteria for what counts as a "Disney movie."
