* ActingForTwo: Or rather, acting for four, in the case of Peggy Lee, who does the voices of Darling, Si, Am and Peg.
** And in the case of Bill Thompson, acting for ''five'', doing the voices of Jock, Joe, two of the dogs at the dog pound (the bulldog and the dachshund), and the policeman at the zoo.
* AFIS100Years100Passions: #95
* AuthorAppeal: The movie is set during TheGayNineties because Walt Disney was a big fan of that particular time period, and the town in the movie was inspired by his own hometown of Marceline, Missouri.
* BasedOnATrueStory: The first scene, anyway. WaltDisney once gave his wife Lillian a puppy as a Christmas present, and he put it in a hatbox to heighten the surprise.
* TheDanza: Peggy Lee not only voices Darling and the two Siamese cats, she also voices Peg, one of the dogs at the pound.
* FakeNationality: Despite the wide range of international characters throughout the film, there are quite a few instances of this:
** Peggy Lee (Swedish Lutheran) [[{{Yellowface}} as the two Siamese cats]].
** Alan Reed (American Jew) as [[FakeRussian Boris the Russian Wolfhound]].
** Bill Thompson (native of Terre Haute, Indiana) as Jock the [[UsefulNotes/{{Scotland}} Scottish terrier]], Dachshie the German dachshund, [[FakeBrit Bull the English bulldog]], Joe one of the two {{Italia}}n chefs, and the [[{{Oireland}} Irish]] [[OfficerOHara Police Officer]].
* HeyItsThatSound: The zoo hyena's laugh was later heard in ''Film/{{Elf}}'' from a jack-in-the-box, and in the ''Franchise/CrashBandicoot'' video games as the "voice" of Ripper Roo.
* KeepCirculatingTheTapes: The version that Disney animated in the 1.37:1 Academy ratio, for theaters unable to show widescreen movies, has only received one official Creator/WaltDisneyHomeVideo release. In 1998, Disney released it on VHS and LaserDisc, as part of the WaltDisneyHomeVideo/WaltDisneyMasterpieceCollection. Reissues of the movie on newer formats only feature the [=CinemaScope=] version, leaving the Academy version unable to view, aside from some clips included in some of the bonus features.
* RealLifeRelative: Verna Felton (Aunt Sarah) was the mother of Lee Miller (Jim Dear).
* ScrewedByTheLawyers: Peggy Lee sued Disney when Creator/WaltDisneyHomeVideo first released the movie on [[UsefulNotes/{{VCR}} VHS]] and LaserDisc, under the WaltDisneyHomeVideo/WaltDisneyClassics label in 1987, citing that her contract did not allow them to use her voice on video. She eventually collected a seven figure sum, and Disney began including in their contracts rights to "media not yet existing."
** The same thing happened with the Mexican Spanish dub, as Tramp's voice actor (Roberto Espriu) sued Disney for the same reason, forcing Disney to do another new dub with a different cast.
* TalkingToHimself: Peggy Lee, Dallas [=McKennon=], Lee Millar and Bill Thompson each perform more than one role in the film.
* TropeNamer:
** SpaghettiKiss
* UrExample:
** This was the first animated feature screened in Cinemascope, the first Disney animated feature to be distributed under Buena Vista Distribution (as opposed to RKO Radio Pictures, as previous ones had) and also one of the first animated Disney films to be (mostly) based on an original story by Joe Grant.
** The casting of Peggy Lee as voice actor and songwriter was also one of the earliest examples of a "big name" in an animated feature at the time.
* WhatCouldHaveBeen:
** [[spoiler: Trusty]] was supposed to die after [[spoiler: the dogcatcher's wagon hit him]], but WaltDisney didn't want another serious death, following the trauma Disney/{{Bambi}}'s mom's demise caused many children.
** Boris the Russian Wolfhound (who appears at the pound) was originally supposed to be the male lead of the film, having Tramp's role. However, the title "Lady and Boris"..."just didn't have the right ring to it".
** Tramp/Boris was also supposed to have had a song, called "''I'm Free as the Breeze''", which he sang about his life as a happy stray. It was cut when the film was {{retool}}ed.
** In one early version, the rat spoke and was more of a troublemaker than a genuine menace. He would have had a Jersey gangster sort of personality. His name would also have been Herman.
** Si and Am were supposed to be seen in the aftermath of the rat attack, looking [[EvenEvilHasStandards shocked at the outcome]].
** A dream sequence was animated where the dogs took their owners for walks, but cut due to negative audience reactions.

* The Classics tape that got Disney sued by Peggy Lee was the final sales tape to contain the early "Cheesy Diamond" The Classics: Walt Disney Home Video logo with the spinning logos, as well as the last new tape to have the line's logo on the back of the tape's case. It's also one of only two "Cheesy Diamond" tapes to not have a later Sorcerer Mickey Walt Disney Classics reprint [[note]] At least in the United States; a French VHS has the 1989 Sorcerer Mickey Walt Disney Classics logo on it [[/note]]; the other was ''Disney/SleepingBeauty'', which followed ''Lady and the Tramp'' back into the vault.
* The Masterpiece Collection tape a decade later was one of two titles in that line to have a widescreen version made, and again, ''Sleeping Beauty'' was the sister title to that.
