The running gag where two of the fairies argued about what color Princess Aurora's dress should be (pink or blue) comes from the filmmaker's problem as to deciding just that.

The last fairy tale produced by the studio until The Little Mermaid (1989), thirty years later.

Princess Aurora's long, thin, willowy body shape was inspired by that of Audrey Hepburn.

In the traditional Italian version of this fairy tale, Sleeping Beauty is named Princess Aurora. In the German version, she is named Briar Rose. The film incorporates both names by having Princess Aurora use the name Briar Rose while undercover.

Second only to Dumbo (1941) (who didn't speak at all), this Disney title character has only about eighteen lines of actual dialogue throughout the entire film, in which she only appears in the film for eighteen minutes and which is actually about the three fairies who protect her, not about the Sleeping Beauty herself. Briar Rose/Aurora's first line is spoken nineteen minutes into the film and her last is delivered after she learns of her betrothal thirty-nine minutes in. However, she does sing two songs during this time frame. The very last sound she makes in the movie is when she arrives at the castle and is crying about never seeing her true love again.

Eleanor Audley--one of Walt Disney's favorite voice artists, most memorably as Lady Tremaine in Cinderella (1950)--initially turned the part of Maleficent down, much to Disney's surprise. As it later transpired, Audley was in the midst of battling a bout of tuberculosis and did not want to tax her voice too much. Fortunately, she recovered and accepted the part.

Even though it is not mentioned in the film, Maleficent's pet raven is named Diablo.

One of the film's iconic scenes, when Briar Rose (Aurora) meets Prince Phillip for the first time to the tune of "Once Upon a Dream," was called "Sequence 8" when it was being produced. It was a particularly hard sequence to get right (Walt Disney rejected it several times) and ultimately had to be done four times, almost bankrupting the studio in the process.

HIDDEN MICKEY: When the fairies discuss how to help the king and queen, Merryweather makes cookies in the shape of Mickey Mouse.

Much of the musical score is based on Pyotr Ilyich Tchaikovsky's ballet "Sleeping Beauty." The musical score throughout the film was recorded by the Berlin Symphony Orchestra. The ominous piece of music to which Maleficent hypnotizes Aurora into pricking her finger is called "Puss-in-Boots and the White Cat." In Tchaikovsky's ballet, it is used for a comic number in which two cats snarl at and try to scratch each other. Various movements from The Sleeping Beauty ballet underwent some reworking for the Disney film. The opening song ("Hail to the Princess Aurora") is actually the ballet's second movement, after the overture. Also, the theme playing when the three fairies clean the cottage is based on "The Silver Fairy" movement, which, in its original form, is barely a minute long.

The prince is named after Prince Philip, the Duke of Edinburgh and husband of Queen Elizabeth II of Great Britain, as well as Prince Philip of Belgium (now King Philip).

Walt Disney suggested that all three fairies should look alike, but veteran animators Frank Thomas and Ollie Johnston disagreed with this idea, saying that having them be alike would not be exciting. Also, the idea originally included seven fairies instead of three, as in the original fairy tale.

Sleeping Beauty (1959) was in production at the Disney Studios for nearly a decade. Story work began in 1951, voices were recorded in 1952, the actual animation took place between 1953 and 1958, and the stereophonic score was recorded in 1957. The movie was finally released one to two years later, in 1959.

A flamethrower was used to create the dragon breath sound effect for the climax of the movie. Castanets were used for the sound of its snapping jaws.

At the time, Sleeping Beauty (1959) was the most expensive Disney animation. Although it was a hit on its initial release, it still did not gross enough to recoup its $6 million outlay.

The second-highest grossing film of 1959 due to its re-releases, just behind Ben-Hur (1959).

For the first time on a Disney animated feature, one man, Eyvind Earle, was in charge of the color styling, background design, and the overall look of the film, even painting the great majority of the production backgrounds. Earle's modernistic approach to design and painting resulted in providing this film a bold, unique art style, even though his colleagues did not care for his production methods and art style while the film was in production. The elaborate background paintings usually took seven to ten days to paint. By contrast, a typical animation background takes one workday to complete.

The restoration process involved four painstaking steps. The first step was to scan the original negative into a computer and subject the entire print to a deflickering procedure, evening out all the worn images and creating a cohesive canvas upon which the restoration artists could work. This was then followed by roto-scoping to extract the principal characters, dust-busting to remove all traces of dust and scuffing, and then re-inserting the characters into their cleaned-up backgrounds. Then all 180,000 frames would be completely repainted by up to forty people in a process that clocked up nearly 48,000 hours. Once complete, the final product is then scanned onto a new negative.

Walt Disney's constant mantra to his animators was that the film could not be like Snow White and the Seven Dwarfs (1937).

Walt Disney had toyed with the idea of a royal couple dancing in the clouds as a finale for both Snow White and the Seven Dwarfs (1937) and Cinderella (1950). The concept finally got used in Sleeping Beauty (1959), and was later re-used in Beauty and the Beast (1991) and The Princess and the Frog (2009). A similar image had appeared in the Bongo (1947) segment in Fun & Fancy Free (1947).

The fairytale book used in the beginning of the movie was real, and was handmade by Eyvind Earle, the man responsible for the entire look and feel of the movie. It was restored in 2008 and is displayed sometimes during public events.

Such was the attention to detail brought about by the widescreen process was that some of the character animators were only capable of producing one drawing of their characters a day. Twenty-four drawn images are needed to make up one second of movement on film.

The Disneyland castle was named for this film, even though the park opened four years prior to the film's release. To help promote the film, the imagineers working on the new Disneyland project modeled the castle after the one in the film.

Animator Eric Cleworth based the dragon's head movements on those of a rattlesnake about to strike.

The first Disney animated film on which Walt Disney personally worked to be released in high definition.

Famed Warner Bros. animation director Chuck Jones worked on the film briefly when Termite Terrace closed temporarily during the late 1950s. He found the atmosphere at Walt Disney Productions oppressive because everything anyone did there had to be approved by Walt Disney before, during, and after the process of production. He was more than happy when Warner's animation department re-opened, where he stayed until it closed again in 1964.

Several story points for this film came from discarded ideas from Walt Disney's previous fairy tale involving another sleeping heroine, Snow White and the Seven Dwarfs (1937); they include Maleficent's capture of the Prince and the Prince's daring escape from her castle. Disney discarded these ideas from "Snow White" because he believed that his artists were not able to draw a human male believably enough.

Bill Shirley and Mary Costa auditioned together to ensure that their voices complemented each other's.

This was the last Disney feature to have cels inked by hand. From One Hundred and One Dalmatians (1961) onward, the cleaned-up pencil drawings were xeroxed onto the cels. However, some of the scenes in this movie did use the xerography process.

Aurora's hair does not stay "sunshine gold" throughout. Rather, it alters between flesh and peach color throughout the movie. There are only a few scenes that she actually has gold hair.

Art direction for this movie was inspired by European medieval painting and architecture.

Only one other Disney animated film, The Black Cauldron (1985), was shot in the same format of Technirama.

The third Disney film to undergo a painstaking computer restoration, after Snow White and the Seven Dwarfs (1937) in 1987 and 1993, and Pinocchio (1940) in 1992.

Studio trademark: Habitually barefoot character(s): Aurora is barefoot for all but the very last scene.

The voice of Maleficent is Madame Leota in The Haunted Mansion attraction at Disneyland California.

Viewers never get to find out what gift Merryweather was meant to bestow upon the princess - wisdom or compassion would have been obvious choices - but according to the platinum edition DVD's commentary, her gift was going to be happiness.

Shot on a 35mm Technirama double-frame negative (which is as big as two regular Academy frames joined together) running horizontally through the animation camera, with each frame photographed three times (once with a red filter, once with a blue filter, and once with a green filter). This negative was then printed on both CinemaScope-compatible anamorphic film and Super Technirama 70mm film, the first film released in Super Technirama 70.

This is the only Disney movie with square trees.

One song which was abandoned was "Evil-Evil," and it was to be sung by two of Maleficent's henchman (who also happened to be brothers). It described their hatred of mankind and desire to cause them problems.

One of the first instances when the movie soundtrack album featured the orchestral score instead of just songs from the film. This set the precedent for soundtrack albums that followed.

The first Disney animated feature to be created ostensibly for the 70mm format.

Queen Leah is the first mother of a Disney Princess to be alive during the film. This would not happen again until Mulan (1998).

Live actors in costume served as models for the animators. The role of Prince Phillip was modeled by Ed Kemmer, who had played Commander Buzz Corry on television's Space Patrol (1950) five years before Sleeping Beauty (1959) was released. For the final battle sequence, Kemmer was photographed on a wooden buck. All the live actors' performances were later screened for the animators' reference. Among the actresses who performed in reference footage for this film included Frances Bavier, Spring Byington, and Madge Blake, the latter two of whom did some live-action doubling as the fairies. The voice artists were not chosen to do so for the fairies because they were not pudgy enough, though Merryweather's face does bear some resemblance to Barbara Luddy.

In 1960, to promote the release of the film in Japan, Walt Disney handpicked some 250 cels, backgrounds, preliminary paintings, animation drawings, and story sketches to send to that country for a touring exhibition. Although the material was mostly for Sleeping Beauty (1959), Disney also provided examples from other films as well, including the only known cel and background setup from Flowers and Trees (1932). The exhibition opened at the Mitsukoshi department store that May and then traveled to sixteen other stores throughout Japan. After the tour, Disney donated the artwork to Tokyo's National Museum of Modern Art. However, the material did not fit well into its permanent collection, so the museum gave the artwork to Chiba University to enhance the study of the school's visual arts program.

King Stefan's and King Hubert's argument (which is centered around them singing "Skumps," a drinking song) originally took place at the beginning of the film. They sang a song called "It Happens I Have A Picture," in which they proudly presented portraits of their children to each other. The demo of the song, which appears on the Legacy Collection edition of the soundtrack, was performed by Hans Conried (as Stefan) and Bill Thompson (as Hubert).

Was re-released in the United States in 1970, 1979, and 1986. It was also re-issued in a few European countries in 1995. It was originally supposed to be re-released in America in 1993 as promoted on the 1992 VHS of Beauty and the Beast (1991), but no further evidence existed of these plans and was most likely to have been cancelled by Disney.

George Bruns initially started scoring the film in Los Angeles in 4-track stereo, until he got wind of a new studio in Berlin that used 6-track stereo, so he decamped for Germany. Bruns' efforts were rewarded with an Oscar nomination.

For several years it was largely unknown who voiced Queen Leah (Aurora's mother), due to her being uncredited. Her lines were recorded by Verna Felton.

Hans Conried, best known as the voice of Captain Hook/Mr. Darling in Peter Pan (1953), recorded dialogue as King Stefan before Taylor Holmes was cast.

Many elements of Sleeping Beauty (1959) have been recycled into later films. The best example is The Sword in the Stone (1963), which reuses opening credit backgrounds and various animation sequences; the two most noticeable are the owl from the forest scene, who would inspire Merlin's pet Archemedes, and Malificent in dragon form, which led to Madam Mim in dragon form.

In active production from 1951 until the end of 1958, setting a record (for which it is tied with another 70mm film, The Black Cauldron (1985)) for being the Disney animated film with the longest production schedule.

In its original release, Sleeping Beauty (1959) was preceded by the featurette Grand Canyon (1958).

Despite the film being about her, Sleeping Beauty or Aurora only says about 18 lines in the whole film.

The song "Once Upon a Dream," is largely based on the Op. 66, Waltz of The Sleeping Beauty ballet, composed by Tchaikovsky.

The huge cost of " Sleeping Beauty " was a massive concern for Walt Disney who slashed his animation personnel from 551 to just 75 the following year. In fact, Disney was advised to pull out of animation altogether and concentrate on TV and theme parks instead.

The look of Maleficent was mainly inspired by actress Maila Nurmi's character Vampira who took most of her inspiration from Morticia Addams and coincidentally The Evil Queen from Walt Disney's Snow White and the Seven Dwarfs (1937).

It took Disney product eight years to make and a million dollars to finance, making it one of the most expensive movies of all time. Adding for fluctuations - about $68 million to make in 2018.

There was a scene storyboarded in which one of the fairies was attempting to make the cake without using the wand, but ultimately caused it to crash right through the roof. Ultimately, Walt Disney decided not to use it as he felt it was one gag too many.

In the penultimate scene where Maleficent appears in the fireplace and hypnotizes Aurora, the female vocalist that is heard while the fire is burning out is actually saying "Aurora!" and is sung none other than Mary Costa herself. While difficult to hear in the film, it is much more clearer on the score/soundtrack.

Amongst Aurora's animal friends in the forest are three birds who individually are red, green and blue in colour - the same colors as the three Good Fairies.

The fourth of Disney's Untouchables to be released on home video.

The character Maleficient is pictured on one of ten USA nondenominated commemorative postage stamps celebrating "Disney Villains", issued as a pane of 20 stamps on 15 July 2017. The set was issued in a single sheet of 20 stamps. The price of each stamp on day of issue was 49¢. The other villains depicted in this issue are: The Evil Queen from Snow White and the Seven Dwarfs (1937), Honest John (Pinocchio (1940)), Lady Tremaine (Cinderella (1950)), The Queen of Hearts (Alice in Wonderland (1951)), Captain Hook (Peter Pan (1953)), Cruella De Ville (One Hundred and One Dalmatians (1961)), Ursula (The Little Mermaid (1989)), Gaston (Beauty and the Beast (1991)), and Scar (The Lion King (1994)).

The second Disney animated feature to be filmed in the 2.35:1 aspect ratio. The first was lady and the tramp (1955)

Despite being the titular role, Aurora's screen time is only 18 minutes in the film.

The first Disney animated film where the Prince (Prince Philip) takes an active role in defeating the main villain. The Evil Queen/Witch fell off a cliff in Snow White and the Seven Dwarfs (1937) and Lady Tremaine was left with her daughters after Cinderella (1950) married her Prince, who did nothing. Philip actually kills Maleficent in the film.
