Frozen is a 2013 American 3D computer-animated musical fantasy–comedy film produced by Walt Disney Animation Studios and released by Walt Disney Pictures. It is the 53rd animated feature in the Walt Disney Animated Classics series. Inspired by Hans Christian Andersen's fairy tale The Snow Queen, the film tells the story of a fearless princess who sets off on an epic journey alongside a rugged iceman, his loyal pet reindeer, and a naive snowman to find her estranged sister, whose icy powers have inadvertently trapped the kingdom in eternal winter.
Frozen underwent several story treatments for years before being commissioned in 2011, with a screenplay written by Jennifer Lee, and both Chris Buck and Lee serving as directors. It features the voices of Kristen Bell, Idina Menzel, Jonathan Groff, Josh Gad and Santino Fontana. Christophe Beck, who had worked on Disney's award-winning short Paperman, was hired to compose the film's orchestral score, while husband-and-wife songwriting team Robert Lopez and Kristen Anderson-Lopez wrote the songs.
Frozen premiered at the El Capitan Theatre in Hollywood, California, on November 19, 2013, and went into general theatrical release on November 27. It was met with strongly positive reviews from critics and audiences, with some film critics considering Frozen to be the best Disney animated musical feature film since the studio's renaissance era. The film was also a massive commercial success; it accumulated nearly $1.3 billion in worldwide box office revenue, $400 million of which was earned in the United States and Canada and $247 million of which was earned in Japan. It ranks as the highest-grossing animated film of all time, the fifth highest-grossing film of all time, the highest-grossing film of 2013, and the third highest-grossing film in Japan. By January 2015, Frozen had become the number-one Blu-ray Disc in the United States. Frozen won two Academy Awards for Best Animated Feature and Best Original Song ("Let It Go"), the Golden Globe Award for Best Animated Feature Film, the BAFTA Award for Best Animated Film, five Annie Awards (including Best Animated Feature), two Grammy Awards for Best Compilation Soundtrack for Visual Media and Best Song Written for Visual Media ("Let It Go"), and two Critics' Choice Movie Awards for Best Animated Feature and Best Original Song ("Let It Go"). An animated short sequel, Frozen Fever, will premiere in March 2015.
