Frozen is a 2013 American computer-animated musical fantasy film produced by Walt Disney Animation Studios and released by Walt Disney Pictures. The 53rd Disney animated feature film, it is inspired by Hans Christian Andersen's fairy tale "The Snow Queen". The film depicts a princess who sets off on a journey alongside an iceman, his reindeer, and a snowman to find her estranged sister, whose icy powers have inadvertently trapped their kingdom in eternal winter.
Frozen underwent several story treatments before being commissioned in 2011 as a screenplay by Jennifer Lee, who co-directed with Chris Buck. The film features the voices of Kristen Bell, Idina Menzel, Jonathan Groff, Josh Gad, and Santino Fontana. Christophe Beck was hired to compose the film's orchestral score, while Robert Lopez and Kristen Anderson-Lopez wrote the songs. Frozen had its general theatrical release on November 27, 2013.
It was praised for its visuals, screenplay, themes, music, and voice acting; some film critics consider Frozen to be Disney's best animated film since the studio's renaissance era. Frozen won a significant number of major awards, including the Academy Awards for Best Animated Feature and Best Original Song, the Golden Globe Award for Best Animated Feature Film, the BAFTA Award for Best Animated Film, and two Grammy Awards.
During its theatrical run, the film was a significant commercial success, earning $1.280 billion in worldwide box office revenue. It also overtook Toy Story 3 to become the highest-grossing animated film of all time, and carried its position until it was overtaken by the remake of The Lion King in 2019. It also became the fifth highest-grossing film of all time and the highest-grossing film of 2013. By January 2015, the film became the best-selling Blu-ray Disc in the United States, which resulted in the film to launch a franchise, including an animated short in 2015, an animated featurette in 2017, and a feature-length sequel, Frozen II, in November 2019.
