* ColbertBump: Like ''Franchise/{{Tron}}'' before it, an appearance in ''Franchise/KingdomHearts'' did a lot to raise the film's profile.
%%ZCE* DirectToVideo: One of the better films in this category.
* DuelingWorks: With ''Film/LooneyTunesBackInAction''. Both films feature the most iconic characters of their respective studios. Despite ''Back in Action'''s underperformance at the box office. ''The Three Musketeers'' was the winner.
* FakeNationality: We have the Troubadour, a French character, voiced by Creator/RobPaulsen, an American voice actor.
* FranchiseKiller: The film's lukewarm reception has caused Disney to shy away from making further films based on [[WesternAnimation/ClassicDisneyShorts Mickey and friends.]] While the Sensational Six have continued to live on in other media like television and video games, there hasn't been a film starring them since.
* TheOtherDarrin: In the Latin American Spanish dub, Rubén Cerda was unable to reprise his role as Mickey Mouse due to a financial disagreement with Disney Character Voices International, so Creator/ArturoMercadoJr took over as the character's permanent voice actor.
* WhatCouldHaveBeen: Besides the deleted scenes featured on the DVD, there were a few other meta-gags that were deleted from the film.
** In an earlier version of the film where Mickey, Donald and Goofy were consulting the actual book, the trio realized that they didn't have a D'Artagnan equivalent. Suddenly, a live-action Michael Eisner would appear on-screen to volunteer to be the Fourth Musketeer, excitingly swinging a sword and prompting the trio to just slowly walk away in a split-screen shot. This would've implied the film would used the RogerRabbitEffect, with the Sensational Six being animated, and everything else being live-action.
** When Mickey nearly drowns in the dungeons, he has a brief near-death experience where he literally meets his maker and proceeds to brief Walt on how the Ride/DisneyThemeParks are doing.
-->"Well, Roy finished Disney World. But I bet you knew that already. Then we built theme parks in Tokyo & Paris. Plus three more in Florida. [[SelfDeprecation Then Michael got this crazy idea to build one that celebrated California. Right in Disneyland’s parking lot. But that didn’t work…]]"
