In the earlier stages of the film's production, Anna's role was vastly different from that of the final project. Instead of being a princess, Anna was a peasant on a quest to have the Snow Queen help free her frozen heart. Not only that, she was of no relation to Elsa in these stages of the film's production. The filmmakers struggled to find the movie's heart through this version, finding it difficult to have a believable and engaging relationship between the two female leads when they truly have nothing to do with one another. However, one of the filmmakers suggested the two be made siblings, and things quickly changed from there. Anna was made a princess, as well as Elsa, who, in turn, went from a villain to a misunderstood heroine.
Anna's voice actress, Kristen Bell, served as one of the prime inspirations for the character. The filmmakers, as well as Bell, wanted a heroine different from the trademark princesses of Cinderella and Belle; one who was clumsy, socially awkward and constantly spoke before she thought. Anna's supervising animator, Becky Bresee, noted she took much of Anna's animated movement from Bell's facial expressions and rhythm when she recorded the lines.
Quite notably, however, Anna has exhibited examples of above-average physical strength and has proven herself to be quite powerful in this regard; she doesn't seem to notice, as she has accidentally caused physical pain to characters such as Kristoff (when she nonchalantly threw a bag of carrots to the mountain man, but with far more force than intended) and Olaf (when she attempted to gently insert his carrot nose onto his face, only to jab it in forcefully and giving the snowman a "head rush" by mistake) as a result of underestimating her own strength. During "For the First Time in Forever", she was seen dancing with and subsequently flinging a bust with ease. During a wolf attack, she held her own, using Kristoff's lute to smack one of the wolves away from the sled - which had brutal results for the wolf. The most noteworthy example of Anna's physical capacity is perhaps following the film's climax, where the princess punched the traitorous Prince Hans off a ship, with a substantial amount of force strong enough to send the prince flying off of his feet.
Anna also has an incredible amount of endurance in harsh winter conditions, as she was able to navigate through post-blizzard terrains with a simple cloak and ball gown for over twenty-four hours or so, without too much negative effect other than some initial discomfort towards the unexpected cold. Following the purchase of her winter gear, she seemed entirely unaffected by the weather and only fell into the danger of freezing to death due to the frozen curse accidentally placed upon her heart by Elsa in the midst of her journey, as its power froze the princess from the inside out. As a young child, she was also unaffected by the snow figures she and Elsa played within the enchanted forest she made with her ice magic (barefoot, no less).
As she walks off, Anna bumps into Hans once again, who takes the princess out on a romantic date around the city. Anna falls in love with Hans, and the night ends with a proposal from Hans. Anna immediately agrees, and the newly engaged couple return to the ballroom to ask for Elsa's blessing. Elsa refuses, telling Anna that she can't marry someone she met, only for Anna to hiss back that shutting people out is the only thing Elsa is good at. This leads to a heated argument between the sisters, which climaxes with Anna questioning why Elsa coldly shuts out her family and the world. Anna's prying triggers Elsa's anxieties, causing the queen to inadvertently unleash her powers upon Anna and their guests. Horrified by what she's done and the way everyone reacted, Elsa flees the ballroom. Despite her confusion, Anna follows behind in an attempt to stop her sister. Elsa escapes into the fjords and unknowingly places a curse that traps Arendelle in an eternal winter. As snow flurries fill the sky, the Duke of Weselton goes into a panic, exclaiming that Elsa must be apprehended. Claiming responsibility for Elsa's departure and the curse, Anna makes it her mission to find Elsa and save the kingdom. With Hans in charge in her absence, Anna leaves the castle on horseback, searching for her sister.
Upon seeing her sister's lifeless body, Elsa breaks down in tears. Kristoff, Olaf, and Sven arrive shortly afterward and mourn the loss of the princess, as Arendelle's onlooking populace does the same. Fortunately, Anna's sacrifice for Elsa has constituted an act of true love, thus breaking her curse and thawing her frozen heart. Anna and Elsa embrace and profess their love for each other. With help from Olaf, Elsa comes to realize that love is the key to controlling her powers. As Anna watches in amazement, Elsa frees Arendelle from its eternal winter, effectively restoring peace to the kingdom. Hans, meanwhile, regains consciousness and is shocked to find Anna alive. Anna calmly confronts him before fiercely punching him in the face and knocking him into the fjord. Anna and Elsa share another hug, and as the sisters embrace, Anna looks lovingly at Kristoff, showing that she reciprocates his romantic affections.
In Ralph Breaks the Internet, Anna is a netizen who lives and works in Oh My Disney as a cast member where she and the other Disney princesses meet and greet their fans. When Vanellope glitches into the princesses' dressing room to hide from the First Order Stormtroopers, Anna is seen talking with Elsa and Moana. When the princesses mistake Vanellope for a threat, they charge at her with various weapons; Anna is the only princess shown without a weapon, instead opting to use her fists (a reference to when she punched Hans). Vanellope explains that she is also a princess, which surprises Anna and prompts Pocahontas to ask what kind of princess she is. Anna, Mulan, Merida, and Moana are the only ones who do not ask Vanellope a question. When Jasmine asks Vanellope if she has "daddy issues", she notes that she does not have a mom, to which Anna and Elsa relate.
After declaring Vanellope an official princess they admire her "gown" and change into comfortable modern clothes. Anna wears a green flannel shirt with a black top with a graphic of a sandwich that reads "FINISH EACH OTHER'S", blue jean shorts, and black-and-white sneakers and is seen lounging next to Tiana while eating a bag of potato chips. Before Vanellope leaves, Merida tries to give her advice in an unintelligible Scottish accent which confuses Vanellope, and she asks the princesses what Merida said and they explain that they cannot understand Merida with Anna adding that she is from "the other studio".
In the climax of the film, Anna and the princesses witness Ralph about to fall to his death from the Google tower and work together to save him. Anna and Cinderella help Jaq and Gus sew two of the princesses' discarded dresses to Rapunzel's magic hair to use as parachutes. After Ralph is saved, the princesses introduce themselves as friends of Vanellope and befriend Ralph as well.
The site is soon attacked by the Fire Spirit, and Elsa uses her powers to put out its flames (and saves Anna from suffocating after she runs into the flames). Elsa tames the spirit, an agitated fire salamander, and names it "Bruni". After the Northundra recognize their mother's scarf as Northuldran-made, the two princesses realize their mother was the Northuldran girl who saved their father's life, ceasing conflict between the two groups as the Northuldra sing "Vuelie" and welcome the royal sisters into their tribe, and Elsa promises to find the truth of the past and free the forest, despite Anna's concern at how big that promise is that Elsa needs to keep.
Before they leave, Anna finds that Kristoff had run off to deal with matters of his own. Believing this to be another sign of rejection, Anna chooses to leave Kristoff behind for the sake of protecting Elsa. The sisters are guided by Bruni and Gale to the shipwreck of their parents, washed ashore from the Dark Sea. There, they find a note explaining that the monarchs were searching for Ahtohallan to find answers about Elsa's magic. Elsa, knowing that sending Anna and Olaf with her would upset the balance between both worlds and that it's too risky for both of them, declares that she must journey to Ahtohallan alone to find the voice. Anna insists on joining Elsa to protect her from Ahtohallan's curse and reminded her the warning in their mother's song, "Go too far and you'll be drowned", but Elsa instead sends Anna and Olaf off on an iceboat to keep them out of danger, infuriating both the princess and Olaf. Anna and Olaf find themselves in the Earth Giants' territory but are able to escape through a dark cave while avoiding waking them up.
While halfway up the mountain, after escaping the pack of wolves, Anna, Kristoff, Olaf and Sven run into Hans, a prince from the Southern Isles who is on his way to find Elsa himself. Kristoff and Sven leave the group when Anna and Olaf allow the prince to join them on their quest. They eventually find a cabin inhabited by a family before a royal guard arrives and takes them back to Arendelle. Hans then explains she is the lost princess of the kingdom and wishes to be by her side. However, Anna finds him increasingly untrustworthy and runs down to the dungeon to find her sister. The close proximity causes Anna to freeze. But even with the curse's enactment, the snowstorm becoming increasingly dangerous and Hans's ruthless pursuit, Anna braves through the danger. She recovers all of her childhood memories moments upon seeing Hans readying to strike her sister with his sword. She shields Elsa with her body, but the close proximity causes the curse to take full effect, turning her into an ice statue. However, by recovering her memory, the curse is lifted and Anna is ultimately thawed. After Elsa unfreezes the kingdom, Anna returns to the village to talk with her adoptive parents and then returns to her childhood home, where she starts a new future with her sister, as well as a romantic relationship with Kristoff. 041b061a72
