All-Star Cast: Although not as blatantly advertized and abused as Dreamworks Animation, the movies in the canon will occasionally have a staggering roster of A-list celebrities lending their vocal talent. Before 1992's Aladdin introduced Robin Williams as the Genie, Disney preferred actual voice actors. After that, they started to increasingly advertise celebrity roles. Some of the more blatant examples: Mandy Moore and Zachary Levi as the leads in Tangled, Miley Cyrus in Bolt (particularly egregious because she replaced a voice actor who had already recorded most of her lines) and perhaps Mel Gibson in Pocahontas.
Thepackagemovies. Allofthem. With the exception of the Caballeros films (which were released together on 1 DVD in 2006 with minimal advertising), the last home video release of these movies is 2000, as a part of the Gold Collection DVD line, and Disney did not promote any of these releases, hence the movies are only known by animation enthusiasts and collectors nowadays. It's becoming rather odd since various characters from the package movies are represented at the Disney theme parks. note The infamous Mr. Toad ride in Disneyland is a good example, but coming across face characters of the Three Caballeros while visiting Disney is also not out of the question.
The Adventures of Ichabod and Mr. Toad DVDs are a common sight in stores around Halloween and they get a special packaging with a jack-o-lantern stencil or trick or treat bag included, so that one's not always an example.
Some of the racist imagery of their earlier films is downplayed or completely removed in contemporary times. A particularly egregious example is the removal of a black servant pony during a segment of Fantasia.
The Black Cauldron is the biggest one. While Hades (and occasionally, Frollo) appear in merchandising, Disney just wants people to forget The Black Cauldron was even made.
Production Posse: Check any of the credits in the Disney Animated Canon starting with The Aristocats and you'll begin to notice several recurring names in both the cast and crew. Here's a small rundown:
The Dark Age Of Disney:
Phil Harris, Pat Buttram, Sterling Holloway (a remnant from the studio's Golden Age) and George Lindsey.
If the film had a male child protagonist during that period, he was probably voiced by one of animator/director Wolfgang Reitherman's sons.
The Renaissance Age of Disney:
Alan Menken and Randy Newman.
Glen Keane, Andreas Deja, Ruben Aquino, Mark Henn, Tony Fucile.
Gary Trousdale, Kirk Wise, Don Hahn, Roger Allers, Rob Minkoff.
What Could Have Been: Two books have been written on the subject, The Disney ThatNever Was and Disney Lost and Found (focusing on My Peoples and Wild Life specifically alongside deleted segments from completed works.)
Also, The Nightmare Before Christmas was apparently supposed to be Disney's 32nd animated film, to have been released during the 1993 holiday season, with The Lion King, then Disney's 33rd animated film, being scheduled for the 1994 holiday season. Then Nightmare was rebranded as a Touchstone film due to being Darker and Edgier even by Disney's standards (and some of the animated canon's entries are more mature than others) and Lion King found itself pushed forward to summer 1994 and directly replacing Nightmare as Disney's 32nd as a direct result of said rebranding. Had things gone as planned, Nightmare would've been Disney's first non-hand-drawn film, as well as the first and so far only stop-motion entry, in the animated canon.
