Frozen

Fun Facts About Frozen

• Disney's Frozen (2013) is loosely inspired by Hans Christian Andersen's 1844 fairy tale The Snow Queen. But the story was heavily reinmagined: the villainous Snow Queen was transformed into the misunderstood Elsa and focused on sisterly love rather than a kidnapped boy.
• Actress Kristen Bell recorded Anna's dialogue while sick. Some of her lines where you can hear snorting and coughing were kept because they sounded more authentic.
• Olaf the snowman was inspired by a single doodle. He quickly developed from there to a fan favorite character.
• The filmmakers researched snow physics intensely. They consulted snow scientists to make ice, snow, and frost behave realistically.
• Anna's clumsiness and awkward movements were intentionally designed by the animation team to sharply contrast with Elsa's poised, graceful control.
• Elsa's ice palace is designed with high mathematical precision. The staircase incorporates fractal patterns found in nature, particularly reflecting the organic growth of ice crystals and snowflakes.
• Frozen sparked a global sing-along phenomenon, driven by the massive success of its soundtrack and specifically the Oscar-winning "Let It Go" — this song was recorded in over 40 languages.
• The trolls are inspired by Scandinavian folklore and Nordic legends where these creatures were said to dwell in mountains, caves, and forests. But while tradition depicts them as mischievous and ugly, Frozen reinterprets them as magical and benevolent.
