Random Trivia For This Title:
- This was the first Walt Disney animated feature to inspire a sequel. The popularity of the film almost led to a spin-off TV-series in 1989; however, when the animation department green-lit its sequel, The Rescuers Down Under, the project was scrapped. The series was still made, but Bernard and Miss Bianca were replaced with Chip and Dale, and the series was called [Chip 'n' Dale Rescue Rangers].
- Real-life husband and wife John McIntire and Jeanette Nolan both voice characters in the film; Rufus the cat (McIntire) and Ellie Mae the muskrat (Nolan).
- Actor Phil Harris, who had played Baloo the bear in Walt Disney's The Jungle Book, Thomas O'Malley in The AristoCats and Little John in Robin Hood, was almost brought again for yet another comic role in this film. However, the dramatic nature of the film called for comic relief characters and humor gags to be toned down, so only the characters of Orville and Luke were left.
- Penny freezes whenever she gazes into Madame Medusa's eyes. In the mythical legend, those who gazed into Medusa's eyes turned to stone.
- This was Joe Flynn's last film. He recorded his lines as Mr. Snoops only a few weeks before his untimely death in July, 1974. The film was released three years later.
- Fans of Walt Disney animation, and animation in general, have often mistakenly referred to the sometimes "sketchy" style in this film, as well as in others such as The Sword in the Stone and The AristoCats as "lazy" and budget-cut. In fact, the veteran animators working on these films, particularly Milt Kahl, strongly objected to their drawings being altered in any way and demanded that they should appear on the film's animation cels exactly as they had been drawn.Veteran animators Frank Thomas and [?] Ollie Johnston consider it their best picture without Walt Disney. The film even won a Special Citation Award from the National Board of Review in the United States "for restoring and upgrading the art of animation."
- Walter Matthau and Dana Laurita were the original voices for Bernard and Penny, respectively.
- In the scene where Penny is carrying Rufus off to supper, Penny grabs Rufus and uncomfortably carries him off in her arms, pushing him up with her knee as he begins to slip. According to [?] Ollie Johnston, who animated the scene, this was done in order to show the tender affection between Penny and Rufus by having the cat to be too fond of Penny to complain, since it would have been easier for Penny to walk away and have Rufus follow her.
- Madame Medusa's fiery red dress and hair and Penny's light blue overalls use their color to contrast the theme of good and innocence against evil. This use of color for personification was later used in other Walt Disney Company films such as Beauty and the Beast and The Hunchback of Notre Dame.
- The film broke a record for largest box office gains on opening weekend, a record it would keep until the release of Don Bluth's An American Tail.

- The Rescue Aid Society honors their founder, Euripedes Mouse, who removed a tiny needle from a ferocious lion's paw, a clear reference to the classic Aesop fable, "The Mouse and the Lion." Originally, the Rescue Aid Society was to be placed in a hole somewhere, until the idea of a luggage bag in the basement of the United Nations building came up.
- Bernard (Bob Newhart) complains several times that he hates flying. One of Newhart's comedy routines was called, "The Mrs. Grace L. Ferguson Airline (And Storm Door Company)", wherein he explains why he hates to fly.

- HIDDEN MICKEY: A Mickey Mouse watch hangs on the wall in the Rescue Aid Society mouse organization building.
- This is the very first Disney animated classic film to feature a small prologue prior to the start of the opening credits; the credits are thus attached into the storyline as they are shown over images describing the journey of Penny's bottle.

It is also the last Disney animated classic film to receive an Oscar nomination until The Little Mermaid, twelve years later.
