- Author Existence Failure: Walt Disney passed away towards the last leg of the film's production, one day after cast member and frequent Disney voice actress Verna Felton passed away; this is the final film to involve both of them to an extended degree.
- Awesome, Dear Boy: When Louis Prima was approached by The Sherman Brothers to play King Louie, his immediate response to hearing the song and the pitch was to ask them, "What do you wanna do, make a monkey out of me?" When the brothers sheepishly admitted it, Prima's followup was, "You got me!"
- Big Name Fan: Both Brad Bird and Genndy Tartakovsky credit this film as the one which convinced them to become animators themselves. Bird in particular points out the sequence of Mowgli and Bagheera climbing a tree as an iconic example of the kind of physicality animation can have, which he's always trying to live up to.
- Celebrity Voice Actor: The Hebrew dub has the vultures done by an Israeli pop band. Of course, the original English version isn't exactly innocent either.
- Crossdressing Voices: Averted in both the original English version and many other dubs with Mowgli, but played straight in the Mexican Spanish dub of the first film, albeit this is averted as well in the sequel.
- Cut Song: A ton of cut songs are found on the DVD. Here is one of them.
- The Danza: Louis Prima as King Louie.
- Disowned Adaptation: Per word of Chuck Jones in his book Chuck Jones Conversations (who did his own animated adaptations of Kipling's stories), Kipling's daughter hated the Disney movie for being an In Name Only adaptation of her father's work."Before we started our film, I discovered that Kipling's daughter was still alive and called her. In an elegant, British Dowager-like voice, she confirmed my pronunciation (of Mowgli's name) and added "and, I hate Walter Disney." It was the only time I ever heard anybody call him Walter. In her lifetime, she said nobody ever pronounced anything but Mauwgli."
- Dub Name Change: In 1993 Finnish dub, Colonel Hathi was referred to as General Hathi. This change was allegedly done due to a request by Hathi's voice actor in the 1993 Finnish dub.
- End of an Age: Meta-example. This is the final Disney animated film to fully involve Walt Disney himself (along with actress Verna Felton, who died alongside him), and at one point was intended to be the Grand Finale to the Disney Animated Canon altogether before Walt was convinced to greenlight The Aristocats prior to his death.
- Half-Remembered Homage: Walt Disney told his entire staff not to read the original Kipling stories at all. The film was said to be "inspired by" rather than "based on" Kipling's works.

- Playing Against Type: Sterling Holloway, who typically put his highly unique voice to friendly characters like Winnie the Pooh and Mr. Stork, plays the sinister Faux Affably Evil Kaa, who's all the creepier for it.
- Recycled Script: The sequence where Baloo and the monkeys kept taking Mowgli away from each other is a shot-for-shot remake of a similar sequence from The Adventures of Ichabod and Mr. Toad.
- Screwed by the Lawyers: Disney ended up limiting the appearances of King Louie when the widow and family of Louis Prima, the voice of Louie in the original film, sued them over the stunning similarities of Prima's voice when Jim Cummings voiced Louie in TaleSpin. This resulted in Disney writing him out of the sequel, replacing him with an Expy named King Larry in House of Mouse, and have any appearance of him reduced to complete silence until the remake in 2016 (which uses a version of Louie far distanced from Prima's take).
- Unintentional Period Piece: Walt Disney attempted to avert this, specifically the vultures. Hence, the vultures talk like The Beatles (and are caricatures of them) but don't sing like them, as Walt felt that a bunch of Beatles expies would date the film. Instead they sing like a barbershop quartet. Suffice it to say that a Beatles-style number would have aged far better, but considering that barbershop dates back to the early 1880s while the Beatles were still a fairly new fad, how was Walt to know that?
- What Could Have Been:
- The Vultures were originally planned to be voiced by The Beatles and sing a rock song, but the band would end up passing on the offer due to busy scheduling (As well as John Lennon refusing to sing a barbershop quartet number). The Beatles-inspired character designs for the Vultures were kept in the finished film, however.
- It was more than that: Walt Disney realized a 60s rock song would date the film too much, and had it changed to a doo-wop song instead. Plus, John Lennon strongly disliked Disney.
- A rhino character named Rocky, who would have accompanied the Vultures, was originally going to be in the film.
- Before that, the film was a closer and much darker adaptation of the book.
- Louis Armstrong was originally considered for the voice of King Louie, but Walt Disney decided against it to avoid the potential controversy of casting a African American man to voice an apenote .
- Andreas Deja on his blog posted a long list◊ of actors considered for the role of Shere Khan, including (but not limited to) Don Adams, John Carradine, Hans Conried, Boris Karloff, Vincent Price, Basil Rathbone, Don Rickles, and Larry Storch.
- There were plans to include Tabaqui the jackal in the film, as a comic-relief character trying to eat Mowgli (a role eventually given to Kaa), but Disney didn't want to have another canine villain.
