The lantern that Mother Gothel holds during the line, "the plague," in the song "Mother Knows Best," and in the beginning when she is singing to the flower, is the same lantern the Stabbington brothers hold when Flynn sees them across the water.
The character design of Flynn came from the process called the "hot man meeting" by Nathan Greno and Byron Howard, during which they set up a meeting with all of the female employees of the studio in one room and asked them for their opinions of what made a man good-looking, in order to create Flynn's character design with features such as eye color, hair color and style and body type. Video footage showed concept art and photos of various male celebrities, including Johnny Depp, Hugh Jackman, Brad Pitt, David Beckham and Gene Kelly, on the walls of the room.
Disney's previous animated feature The Princess and the Frog (2009), despite being popular with critics and audiences alike, was a box office disappointment. Disney felt that the film's princess theme discouraged young boys from seeing it. In an attempt to market the film to a broader audience, Disney changed the title of the film from Rapunzel to Tangled, and promoted it as a comedic adventure. An early trailer for the film focused less on Princess Rapunzel and more on Flynn Rider, the male lead character. It was originally believed that Disney's marketing campaign was a desperate attempt to search for a particular audience. However, Byron Howard and Nathan Greno, claimed that the title change was to emphasize that Flynn has as much of a role in the film as Rapunzel.
For the scene in which Rapunzel enters the marketplace, the animators were inspired by entrances of Walt Disney World and Disney Land. Rapunzel's excitement towards all the music and people is reminiscent of children at the parks.
An average inch of hair weighs about 50 µg, a light estimate, as blonde hair tends to be lighter than other colors. Animators have said that Rapunzel's hair is approximately 70 feet (840 inches), and consists of about 100,000 strands. That yields 4,200,000,000 µg = 4,200,000 mg = 4,200 g = 4.2 kg (approx 10.4 lbs) of hair. We assume that its manageable weight in the movie is another innate magical property.
Studio trademark: Habitually barefoot character(s): The character of Rapunzel is constantly barefoot, something she shares in common with her voice actress Mandy Moore, who loves to perform barefoot. Bare feet are also symbolic of innocence.
Pinocchio can be found in the Snuggly Duckling, right after the cupid is swung to the right of the screen. He is in the top right corner in the rafters. In addition, Pumbaa from The Lion King (1994) (visible in the same scene) and Louis from The Princess and the Frog (2009) (one of the puppets used later in the song) can also be found. It can be inferred that they are all involved in this scene, due to them all having dreams (Pinocchio: real boy, Pumbaa: accepted despite bad gas, Louis: jazz musician).
The teaser trailer for the movie showed the first meeting between Rapunzel and Flynn quite differently. After hitting him with the pan, Flynn comes to appear but Rapunzel stays out of sight, while her hair punches and grabs him, and drags him around the room in slapstick fashion. When Flynn is tied to the chair and tries his smoldering look on her, she throws him out of the tower while still tied to her hair. There is also an unused scene where Flynn waits at the foot of the tower and gets the full weight of Rapunzel's hair thrown on him, which greatly amuses Maximus, the horse.
From the beginning, Glen Keane intended that the film looked and felt like a traditional hand-drawn film, but in 3-D. He hosted a seminar called "The Best of Both Worlds," where he brought in fifty Disney animators (both CGI and traditional artists) to discuss the techniques used in each style and how to, in his words, "bring the warmth and intuitive feel of the hand-drawn to CGI."
According to Glen Keane, the movie's visual style (a three-dimensional painting) was greatly inspired by the Romantic painting "The Swing," by the French rococo artist Jean-Honoré Fragonard; "A fairy tale world has to feel romantic and lush, very painterly." For a clear idea of what was intended, the animators duplicated the picture in 3-D to achieve a shot containing depth and dimensions.
In the marketplace, when Rapunzel looks at the mosaic of herself, the camera cuts from her eyes to the tile eyes of the picture and, very briefly, there is a clarinet musical motif that is exactly the same as the motif in Ferris Bueller's Day Off (1986), when Cameron is looking at the pointillist painting and the camera cuts between Cameron's eyes, and that of the child in the painting. The moment is just a fraction of a second; just after that, Rapunzel looks at the clarinet player walking behind her, and smiles.
According to production manager Doeri Welch Greiner, the original script was a quasi-sequel to Enchanted (2007), and had Rapunzel turned into a squirrel and her place taken by a girl in the real world. Glen Keane eschewed in favour of a more fun and fantastical fairytale that Disney is famous for: "I think that's what Disney needs to do right now. No one else can do it. We should not be embarrassed or make excuses for doing a fairytale."
The sword that Maximus uses to fight Flynn at the dam is a Roman gladius. This would normally be an anachronism to the time-set of the movie. However, in this case, it is very fitting because the name Maximus is also a Roman name.
The song that activates the power of the magic flower is only sung the whole way through, without breaks, twice--once when Rapunzel heals Mother Gothel (though it was very quickly), and another time when Rapunzel heals Eugene's hand. The rest were separated by scenes or never completed.
In the Snuggly Duckling tavern, the ruffian, "Greno," who leaves to get the guards, is named for and modeled after the film's co-director, Nathan Greno, only much bigger but with the same van Dyke-style goatee and the same arm tattoos.
The algorithm that manages how Rapunzel's hair moves appears to be based on a similar algorithm for cloth. This is noticeable, for example, at the end of the "When Will My Life Begin" montage as she tosses her hair around her in a spiral.
Glen Keane credits animator Kyle Strawitz for achieving the painterly style of the film, saying, "Kyle helped us get that Fragonard look of the girl on the swing. He took the house from Snow White and the Seven Dwarfs (1937) and built it in CGI, and painted it so that it looked like a flat painting that suddenly started to move, and it had dimension and kept all of the soft, round curves of the brushstrokes of watercolor. Kyle really helped me start to believe that the things I wanted to see were possible--that you could move in a Disney painterly world."
The colors of the main characters' clothes are meant to reflect their personalities. Rapunzel wears purple, a color often associated with royalty. Flynn/Eugene wears blue and white, colors that often stand for goodness. Mother Gothel wears red, a color that often symbolizes evil.
Glen Keane's ambition with this film, technically speaking, was to make the computer "bend its knee to the artist" instead of having the computer dictate the artistic style/look of the film, and make the computer become as "pliable as the pencil."
When Mother Gothel is first seen in the tower with Rapunzel, there are several items that reveal Mother Gothel's true intentions, including a spinning wheel (as in Sleeping Beauty (1959)), a pattern of an apple (as in the Evil Queen's apple in Snow White and the Seven Dwarfs (1937)) on the bottom newel post of the stairway, and her lantern emitting a green color (reminiscent of Maleficent's magic, also in Sleeping Beauty).
Because many of the techniques and tools that were required to give the film the quality Keane demanded of, although it did not exist when the project was started, the WDFA had to make them on their own.
According to Glen Keane, the technique of non-photorealistic rendering was extensively used to make the CGI surface look like it is painted, but still containing depth and dimension. He also mentioned the use of subsurface scattering and global illumination and "all of the latest techniques" to render, in computer-generated imagery, convincing human characters and rich environments.
"You Are My Forever" was a deleted song that was meant to be sung to Rapunzel, at different times in the film. Originally, it was to be sung by Mother Gothel in a maternal way. Flynn would later reprise the song in a romantic way. "You Are My Forever" was eventually replaced with the songs "Mother Knows Best" and "I See the Light."
When Mother Gothel is looking for her bricked-up doorway into the tower, the plant covering the base of the tower resembles Campanula rapunculus, commonly known as rapunzel (or rampion) - this plant is the one that the Brothers Grimm used in their original story to give their main character her name. However, rapunzel is not a climbing plant as shown in the movie (it appears to be growing like ivy up the base of the tower) - the animators appear to have taken some creative license with it.
Also in the original Grimm Fairy tale, Flynn Rider was actually a prince and Rapunzel wasn't a princess but born a peasant, Before her birth, her mother saw some rampion growing in Dame Gothel's garden and craved it longingly, Rapunzel's father stole the rampion, the first time successfully but during the second time he got caught and in exchanged for the rampion he had to give up his first child. When Rapunzel was born, the witch appeared and took the child away and named the baby girl after the rampion her mother had craved for. After 12 years Gothel locked Rapunzel in a tower and was the only visitor for some years until a prince came by. In the Grimm story Rapunzel falls for the prince who visits her frequently leading her to become pregnant. Gothel finds out and cuts Rapunzel's hair and banishes her to a desert where she gives birth to twins. The prince arrives at the tower only to learn that the witch is there. In his grief he lets go of the hair and falls into thorns becoming blinded. He wanders through the desert, gets reunited with Rapunzel who cries and the tears restore his sight and they live happily ever after
During the reprise of "Mother Knows Best" (where Gothel manipulates Rapunzel into believing that Flynn doesn't return her feelings), fog surrounds the characters. This is meant to reflect how Gothel is clouding Rapunzel's mind with doubt.
There was at least three different character takes on Flynn. In one he was originally intended to be a wayward prince hanging out with a group of bandits. Later on he was a sort of "bandit prince" and leader of a group of rogues (the rogues themselves eventually became the Snuggly Duckling thugs). Soon he was conceived as a British farmer named Bastian, who was orphaned at a young age and forced into a life of thievery to survive, though he hated it. He was later edited into a Jack Sparrow-esque design before becoming the Flynn seen in the movie.
Scored an Academy Award Nomination for Best Original Song with "I See The Light", but it didn't get a Nomination for Best Animated Feature. It was later widely considered a snub in the category, particularly because the foreign film few people knew existed, "The Illusionist" (2010), was nominated alongside How to Train Your Dragon (2010) and Toy Story 3 (2010).
The trivia items below may give away important plot points.
In the opening scenes, you see baby Rapunzel in her cradle staring up at a baby mobile. In a little bit of foreshadowing, several items are seen hanging from the mobile that come into play later in the story, namely, a chameleon (her pet Pascal), a rubber ducky (the Snuggly Duckling that Flynn takes her to), a cupid (also from the Snuggly Duckling), a horse (Maximus) and a blue bird (when she first leaves the tower).
Whenever Mother Goethel expresses her "love" to Rapunzel, it is always to her hair and not directly to Rapunzel. She kisses Rapunzel on the head and touches her hair whenever expressing love. She also calls her "my little flower," in reference to the original sunflower. By contrast, whenever Flynn is being affectionate to Rapunzel, he always brushes her hair away, so he can see her face better.
While it may seem that Mother Gothel is the eighth animated Disney villain to fall to her death - following the Wicked Queen (Snow White and the Seven Dwarfs (1937)), Ratigan (The Great Mouse Detective (1986)), McLeach (The Rescuers Down Under (1990)), Gaston (Beauty and the Beast (1991)), Frollo (The Hunchback of Notre Dame (1996)), Queen Narissa (Enchanted (2007)), and Charles Muntz (Up (2009)) - she does not in fact die in this manner. She is, however, the only Disney villain to die from extreme and rapid old age - brought on by the sudden loss of the magic effect on her of Rapunzel's blonde hair. She only happened to be falling out of a 70-foot window at the time; once her cloak hits the ground, she has already turned to dust.
In the beginning of the movie, the inside of Rapunzel's tower is bright and full of color. After she returns from seeing the lanterns, it is dull and darkly colored, to symbolize that she no longer sees the tower as amazing.
Mother Gothel is very similar to Judge Claude Frollo from The Hunchback of Notre Dame (1996). Both have no magical powers, both keep a person hostage for their own personal gain, both sing a song to their hostage to keep them from running away, both try to kill their hostage's love interest and both fall to their death.
For most of the film, Flynn calls Rapunzel "Blondie" or "Goldie," even after she tells him her name. He does not call her by her real name until after Mother Gothel and the Stabbington brothers separate them.
