- Celebrity Voice Actor: Dinah Shore was one of the most successful recording artists in the US, and she narrated (and sang) in Bongo.
- Completely Different Title:
- "Coquin de Printemps" (That Cheeky Spring) in France.
- "Bongo e i tre avventurieri" (Bongo and the three adventurers) in Italian.
- Cross-Dressing Voices: Mickey in "Mickey and the Beanstalk" was dubbed by Yoshiko Ohta (of Himitsu no Akko-chan fame) in the 1981 Japanese TV dub.
- Edited for Syndication: When "Mickey and the Beanstalk" was shown on Disney's Wonderful World of Color, the dragonfly battle and the antics of Goofy and the gelatin were shortened.
- Hey, It's That Sound!: During the Bongo segment, when the circus train starts, it's the exact same one as Casey, Jr.'s starting sounds with his circus train from Dumbo (which, funny enough, was meant to be a tie-in piece, as detailed under What Could Have Been).
- The Other Darrin: Both Walt Disney and Jimmy McDonald share the role of Mickey.
- Four dubs of the film exist in Japan (two for television, two for home video), each featuring a different stable of voice actors.
- Refitted for Sequel:
- Mickey and the Beanstalk was going to be part of a proposed package feature that would have featured either The Gremlins or The Wind in the Willows. The former would not be made, while the latter ended up being part of The Adventures of Ichabod and Mr. Toad.
- Jiminy Cricket's song in this film, "I'm a Happy-Go-Lucky Fellow", was originally created for Pinocchio, but was ultimately not used in that film.
- What Could Have Been:
- Earlier versions of the Beanstalk segment had two versions of where Mickey got the beans. One version has Honest John and Gideon being the tricksters who sell Mickey the beans, while another has Mickey meeting the queen of Happy Valley: Minnie, who gives him the beans.
- According to the featurette included on the DVD and on the 1997 VHS and laserdisc, both were originally going to be made into full-length films, with Bongo being a companion piece to Dumbo, to the point where the Elephant Matriarch, Catty, Prissy, and Giddy were to make an appearance. However, when the US entered World War II, the idea was shelved.
- When Bongo was still being developed as a full-length feature, several new characters were added. These included Chimpy, a monkey sidekick for Bongo; a pair of mischievous bear cubs; and Stinky, a manifestation of Bongo's animal instincts. There was even an appearance by Mother Nature, depicted as a flighty business woman. Eventually, the cast was pared down to the original three characters from the Sinclair story.
- Bongo's love interest was named "Susie" and then "Silveryear" before the animators settled on "Lulubelle."
- Dinah Shore would have appeared in live-action framing sequences, narrating the story of Bongo to a troop of girl scouts.
- Originally, Mickey, Donald and Goofy would have had separate adventures before entering the giant's castle, a format borrowed from the shorts starring the three of them together. Mickey would have tried to ride a grasshopper like a horse, Donald would have fallen into a bird's nest and been mistaken for one of the hatchlings, and Goofy would have eaten berries that made him invisible. (The latter two ideas were later worked into two Donald Duck cartoons, "The Contrary Condor" and "The Vanishing Private".) Pluto was also considered as a member of the party, and Clara Cluck would have been the hen that laid golden eggs.
- Walt briefly considered having a framing story in which Mickey and friends threatened to go on strike if they didn't get a feature film. Ironic, considering the studio would go through a bitter strike not long afterwards.
