Hey, It's That Voice!: Anyone who watched sitcoms in the 60s will instantly recognize Bob Newhart (Bernard) and his stutter as well as Eva Gabor (Bianca, who even mispronounces "rollercoaster" the way Lisa Douglas might). Jim Jordan, the voice of Orville, is Fibber McGee from Fibber McGee and Molly. For Down Under, you have George C Scott as McLeach and John Candy as Wilbur.
Mr. Snoops, in the first movie, is Joe Flynn (Capt. Binghamton from McHale's Navy).
Billy Barty played the baitmouse in The Rescuers Down Under.
The first video release of Down Underhas no commercials in either the beginning or the end of the tape.
Every home release for Rescuers from 1999-2003 omits the first Buena Vista logo and replaces it for Disney's (by this time outdated) white castle Vanity Plate.
Some of Madame Medusa's animations served as inspirations for Ursula's.
The Rescuers usually comes with a mouse-related short, usually a Mickey Mouse short, for both theatrical and home releases.
Bowdlerization: In one frame of the movie (theatrically and on the 1992 VHS), when Bernard and Bianca are riding Orville, going down from the building they were on, one building next to them has an image of a naked woman in one of the windows. Disney found this out when the movie was released again on VHS in 1999, and recalled it. The re-issue (and subsequent releases) zooms in on the image of Bernard and Bianca, so the image wasn't visible. According to animator Tom Sito, on his Facebook page, the image was put in by background artist Annie Guenther.
On the 1992 VHS, the "Feature Presentation" screen at the time was a navy blue color instead of light blue. This is then followed by the distorted version of the Walt Disney Classics logo.
What Could Have Been: The first movie was gonna be a very different movie than what was released. It was gonna be a vehicle for Louis Prima (of The Jungle Book), playing Louie the Bear, and, according to the video in the link, to be about a Bear using a pair of mice to help him escape from the zoo to save his friends in the North Pole. This version was scrapped shortly before Prima lapsed into a coma and it was Retooled into the movie we know today.note Prima never regained consciousness from his coma, and died the year after the finished film was released.
Also, before it was completely retooled, the movie's antagonist and villain was originally going to be Cruella DeVille. In fact there is a bit of a Development Gag there - Madame Medusa not only drives very similar to Cruella, but also her car looks to be inspired by it.
In the planning phase of The Rescuers, Orville the albatross was originally a pigeon.
Madame Medusa's swampmobile appears to be powered by a jet engine. This is evidenced by the jet engine-like rear exhaust and the distinctive jet noises the vehicle makes. However, in a later scene in the film, a normal four-stroke engine is shown to lurk under the hood at the front.
The Walt Disney Gold Collection DVD release of The Rescuers Down Under appears to be taken from a low-quality and degraded film print. This release shows all the characteristics of old film - dust specks, fluctuating brightness, and even the slight shifting of the image are present in this print. Ironically, The Rescuers Down Under was Disney's first film to be made entirely within a computer, and since the movie is on DVD, one would expect the full digital clarity present in most DVD movies.
Screwed By the Studio: When the opening box office weekend of the Rescuers Down Under didn't live up to expectations, studio head Jeffrey Katzenberg pulled the plug on the promotional campaign. It also didn't help that the movie competed againstHome Alone.
