The special, according to press notes, "ventures behind-the-scenes for an exclusive look at the origins and evolution of the Academy Award-winning film 'Frozen,' now the biggest animated feature of all time. A breathtaking and fantastic saga, the special tells the real story of making a modern movie based on a timeless tale that nearly overnight became a cultural touchstone for legions of fans."
Viewers will be offered a rare look inside Walt Disney Animation Studios and access to the creative team that brought "Frozen" to life.
This special will include images and footage from the research trips to Norway, Quebec, announcements about the next chapter of "Frozen" and a never-before-seen preview of "Frozen" characters Anna, Elsa and Kristoff on an upcoming episode of ABC's "Once Upon a Time."
Directed by Chris Buck ("Tarzan," "Surf's Up") and Jennifer Lee (screenwriter "Wreck-It Ralph") from a screenplay by Lee, the voice cast of the film features Bell ("Forgetting Sarah Marshall," The Crucible), Menzel (Wicked, If/Then), Jonathan Groff (Spring Awakening), Tony Award nominees Josh Gad (The Book of Mormon) and Santino Fontana (Cinderella), Alan Tudyk (Prelude to a Kiss) and Ciarán Hinds (Cat on a Hot Tin Roof).
The film uses original songs by husband-and-wife songwriters Robert Lopez (The Book of Mormon, Avenue Q) and Kristen Anderson-Lopez as well as an original score composed by Christophe Beck ("The Muppets").
Here's how the film, produced by Peter Del Vecho, is described: "Fearless optimist Anna (voice of Bell) sets off on an epic journey—teaming up with rugged mountain man Kristoff (voice of Groff) and his loyal reindeer Sven—to find her sister Elsa (voice of Menzel), whose icy powers have trapped the kingdom of Arendelle in eternal winter. Encountering Everest-like conditions, mystical trolls and a hilarious snowman named Olaf (voice of Gad), Anna and Kristoff battle the elements in a race to save the kingdom."
Additionally, Disney has released a multi-language version of the film's hit song "Let It Go," which can be seen below.
