Walt Disney Feature Animation's final traditionally animated feature film to be released in cinemas (ending the 44-film legacy that began with Snow White and the Seven Dwarfs (1937)).
Although this film is the last traditionally animated Walt Disney Feature Animation (WDFA) and number 44 on the list, it is actually only number 35 of the traditionally animated WDFA that is made up of a single story. Fantasia and Fantasia 2000 consists of several animated segments, this is also the case for the so-called "package films" (made up of smaller shorts, rather than one long narrative), which were produced during and shortly after the WWII, from 1943 to 1949. These films are Saludos Amigos (1943), The Three Caballeros (1945), Make Mine Music (1946), Fun and Fancy Free (1947), Melody Time (1948) and The Adventures of Ichabod and Mister Toad (1949). The same procedure was used once more with The Many Adventures of Winnie-the-Pooh (1977).
During its theatrical release (first-run and sub-run) in the United States, this film reportedly earned less than half of its estimated production cost. This was one of the final factors that led to the decision to make this the last traditionally ("hand-drawn") animated Disney feature for theatrical release. In early 2006, at the urging of professionals both in and out of Disney, plans were being considered for resuming traditionally animated features for theatrical release starting with The Princess and the Frog (2009).
This film earned its "PG" rating due to one of Maggie's lines about her udders ("Yeah, they're real. Quit staring.")
At one point Maggie refers to Buck as the "stallion of the Ci-moron," a reference to the Dreamworks feature Spirit: Stallion of the Cimarron (2002). Although Dreamworks features often made fun of Disney films, this is the first time Disney has returned the favor.
When Rico sees Mrs Calloway about to crush him, he says "Mother of Mercy. Is the end of Rico?" This same line was spoken by Edward G. Robinson in Little Caesar (1931).
The two vultures who appear near the beginning of the movie are animated in exactly the same way as the vultures in Disney's The Jungle Book (1967/I).
During the second song, the duck that is dancing is doing the "Elaine" dance from "Seinfeld" (1990).
Mexican singer/songwriter Ely Guerra was the voice of Grace in the dubbed Mexican version.
Alameda Slim is named after Wilf Carter also known as "Montana Slim". Carter was known as a Country Singer and Yodeler.
The working title of this film was "Sweating Bullets" and an early plot idea was about a calf named Bullets who saved his herd from a band of ghost cattle rustlers called the Willies.
GOOFY HOLLER: When Junior falls down the elevator shaft.
Writers Will Finn and John Sanford originally pitched the film as an animated feature film based on the myth of the Pied Piper. Maggie the Cow was originally written as a deaf girl. Michael Eisner immediately hated the idea, because he thought no parent would take their children to see a movie where children are murdered. So Will and John wrote this movie, which contains elements from the Pied Piper myth.
