Trivia: The Great Mouse Detective

  • Acting for Two: Barrie Ingham voices both Basil and the unlucky Bartholomew.
  • Awesome, Dear Boy: Price on his role as Ratigan. He had stated that Ratigan was his favorite film role.
  • Dueling Movies: With An American Tail, another animated movie about mice coming out the same year (though it didn't come out until a few months afterward). The Great Mouse Detective lost in the end, but that didn't mean it wasn't successful; in fact, it convinced Disney that its animation unit still had a future.
    • The success of An American Tail probably helped convince Disney as well.
  • Executive Meddling: Largely averted, as Jeffrey Katzenberg had little to no faith this movie would be any good. Most of his attention was spent on meddling with The Black Cauldron, which became a failure. Katzenberg did, however, demand the title of this film be changed from "Basil of Baker Street" to simply "The Great Mouse Detective", a move that inspired an infamous fake memo that became a category on Jeopardy. Two of the four directors have since said they've always hated the new title.
    • However those directors may have had some solace in the title being changed to "Basil the Great Mouse Detective" is some countries, including Australia.
  • Hey, It's That Voice!:
  • Hilarious in Hindsight: The box that Olivia is sitting on when Dawson finds her reads "Dr. Gaston's Liver Pills." 5 years later, we would meet Dr. Gaston, and he was evidently health conscious, based on eating 4 dozen eggs every day.
  • I Am Not Shazam: The lead dancer at the bar is listed in the credits as "Miss Kitty Mouse," but, Fanon aside, this doesn't actually appear to be her name. Rather, it's a description of her. She isn't "Miss Kitty Mouse," but "the Miss Kitty mouse."
  • What Could Have Been: Madonna was considered to voice Miss Kitty and perform the song "Let Me Be Good To You".
    • This isn't as far-fetched as it may seem when one listens to Madonna's jazzy showtunes on the Dick Tracy soundtrack.
    • Olivia was originally planned to be older, acting as a potential love interest for Basil, but it was later decided she should be a child to make her more sympathetic.
    • John Cleese was the first choice to voice Basil.
    • Ratigan's original design was very thin and frail-looking. They changed it after Vincent Price was cast to reflect Price's larger build. Glen Keane also says that he based it partially on then-head of the studio, Ron Miller, an ex-football player.
