The technology change also happened when Disney cut its animation department after the economical failure of the very expensive Sleeping Beauty,
Unlike many other Walt Disney animated features, One Hundred and One Dalmatians features very few songs, only three, with just one, "Cruella De Vil", playing a big part in the film (ironic, considering that Roger was a professional songwriter). Even this song isn't sung in one setting (a scene between Cruella and Anita splits it into two parts). The other two songs are "Kanine Krunchies Jingle" (sung by Lucille Bliss, who voiced Anastasia in Disney's Cinderella), and "Dalmatian Plantation", of which only two lines are sung as the film's closer. The MPAA was close to re-rating this movie due to the new criteria about smoking.
- Several of the characters from Lady and the Tramp (1955) can be seen in a pet shop window during the twilight bark sequence and when Pongo and Perdita fight the Baduns, the same sounds in the background are from the scene that Tramp fights the three alley dogs.
- Cruella De Vil was designed as a manic take-off on the flamboyant actress Tallulah Bankhead, as well as some of her personality quirks.
- This was the final film for animator Marc Davis. After animating Cruella De Vil in this film, Davis went to work for WED Enterprises, designing for such Disneyland rides as the Haunted Mansion and Pirates of the Caribbean.
- Quite a few liberties were taken in bringing the book to the screen. In the original story, the two Dalmatians who ran across England to rescue their pups were named Pongo and Missis Pongo, or just plain Missis; Perdita was a stray whose own puppies had been sold, and who was taken into the household to help wet nurse Missis' fifteen puppies. In the film, their owners are named Roger and Anita Radcliffe; in the book, they're Mr. and Mrs. Dearly, no first names given. The book also features two Nannies (Nanny Cook and Nanny Butler) to the film's one; Jasper appears under the same name in both versions, but Saul is changed to Horace for the film; and Tib, the book's heroic gray tabby female, is transformed into an orange-colored tom.
