Random Trivia For This Title:
- Walt Disney originally didn't want to include the 'Bella Note' spaghetti-eating scene, now one of the most iconic moments in the whole Disney canon.
- To maintain a dog's perspective, Darling and Jim Dear's faces are rarely seen.
- In order to make the climactic fight between the rat and the Tramp more exciting Wolfgang Reitherman animated from the point of view of the loser and then attempted to avoid that particular outcome.
- The studio's first officially self-penned story since Dumbo. The original story was created by Joe Grant while Snow White and the Seven Dwarfs was nearing post-production. Ward Greene used Joe Grant's original version as the basis for his novel. Greene's novel was still being written while the film was still in production. Grant's wife was said to have been angry over the story being "stolen" but Walt Disney maintained all legal rights to the story.
- In making this film, Walt Disney claimed that it was a "fun picture" to make (another example of such a film was Dumbo), because it was an original story and was easily adjustable as they made the film and got to know the characters - there were no pre-existing storylines.
- Hiring Peggy Lee arguably was the first instance of a superstar voice being used for an animated film.
- Barbara Luddy was nearly 50 when she voiced the young Lady.
- A dream sequence where giant dogs take their owners for walks was scrapped because of adverse audience reactions.
- The film's setting was partly inspired by Walt Disney's boyhood hometown of Marceline, Missouri. The film's opening sequence, in which Darling unwraps a hat box on Christmas morning and finds Lady inside, is reportedly based upon an actual incident in Walt Disney's life. After he'd forgotten a dinner date with his wife, he offered her the puppy-in-the-hat box surprise and was immediately forgiven.
- Verna Felton, who voices Aunt Sarah, is the mother of actor Lee Millar, who provided the voice of Jim Dear.
- The first feature-length animated movie to be made in widescreen (2.55:1). Made simultaneously in both a widescreen CinemaScope version and a standard Academy ratio version. It's also the widest film the company has ever created. The decision to film in Cinemascope was made when the film was already in production, so many background paintings had to be extended to fit the new format. Overlays were often added to cover up the seams of the extensions. CinemaScope presented some new problems for the animators. The wider canvas space made it difficult for a single character to dominate the screen, and groups had to be spread out to keep the screen from appearing too sparse. As the release date neared, Walt Disney was dismayed to learn that not all theaters were equipped to show a film in CinemaScope. Consequently, another version of the film had to be made, this time in original aspect ratio.
- Darling's real name is never used, even her friends call her "darling" at the baby shower. It is unclear if that's her name or an endearment.
- As the story was being developed at the studio, Ward Greene wrote a novelization. Walt Disney insisted that this be released some two years before the film itself to give audiences time to familiarize themselves with the plot.
- Peggy Lee later sued Disney for breach of contract claiming that she still retained rights to the transcripts. She was awarded $2.3m, but not without a lengthy legal battle with the studio which was finally settled in 1991.
- In early script versions, Tramp was first called Homer, then Rags and Bozo. A 1940 script introduced the twin Siamese cats. Eventually known as Si and Am, they were then named Nip and Tuck.
- In 1937, story man Joe Grant approached Walt Disney with some sketches he had made of his Springer spaniel called Lady. Disney really liked the sketches and told Grant to put them into a storyboard. However, Disney ultimately didn't think much of the finished storyboard. Six years later, he read a short story in Cosmopolitan by Ward Greene called 'Happy Dan the Whistling Dog'. He was sufficiently interested in the story to buy the rights to it. Then in 1949, after Joe Grant had left the studio, his spaniel drawings were unearthed and a solid story using his designs started to take shape. Grant never received any acknowledgement for his contribution to the film until the Platinum Edition DVD in 2006.
- Included among the American Film Institute's 1998 list of the 400 movies nominated for the Top 100 Greatest American Movies.
- In the film, Tramp never calls Lady by her actual name. Instead, he calls her by the two nicknames: "Pigeon" and "Kid"
- Tramp's predicament in being thought to have attacked a baby when he was protecting it from a predator is a reference to the Folktale of Gellert.
- In the climax of the picture, Trusty was originally killed when hit by the wagon. That is why Jock nudges him and he does not rouse. When Walt Disney viewed this scene, he was shocked, not wanting a repeat of the traumatic scene in Bambi, thinking that it was too intense. Walt then made the animators put Trusty into the end Christmas scene with a Broken Leg to reassure the audience that Trusty was simply knocked out and injured in the previous scene.
- The mischievous young puppy at the end of the film (the one who resembles his father, Tramp) is called "Scamp". He was featured in a children's book, a syndicated daily comic strip, and comic books, before starring in Lady and the Tramp 2: Scamp's Adventure.
