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 the 1844 Danish fairy tale The Snow Queen by Hans Christian Andersen. The film was directed by Chris Buck and Jennifer Lee (in her feature directorial debut) and produced by Peter Del Vecho, from a screenplay written by Lee, and a story by Buck, Lee, and Shane Morris. It stars the voices of Kristen Bell, Idina Menzel, Josh Gad, Jonathan Groff and Santino Fontana. Frozen tells the story of Princess Anna as she teams up with an iceman, his reindeer, and a snowman to find her estranged sister Elsa, 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 Lee. Kristen Anderson-Lopez and Robert Lopez were hired to write the songs for the film, while Christophe Beck composed the score.
Frozen premiered at the El Capitan Theatre in Los Angeles on November 19, 2013, and went into its general theatrical release on November 27. 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 received two awards at the 86th Academy Awards, and numerous other accolades. It was the first Walt Disney Animation Studios film to win Best Animated Feature.
During its theatrical run, the film was a significant commercial success, earning $1.285 billion in worldwide box office revenue, overtaking 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 launching a franchise, including an animated short in 2015, an animated featurette in 2017, and a feature-length sequel, Frozen II, in November 2019.
