Here’s a little excerpt from Frozen’s song Let It Go, sung by someone who attended D23’s Destination D. (not me!)
It was included in this podcast (the Frozen part starts at 48:00) : as no cameras were allowed, they had to write down the lyrics and remember the tune… They also mentioned that they were missing one of the lines, so it’s not the definitive, official, version of the song… But it’s still nice to listen to!
Let it go, let it go
I’m one with the wind and sky
Let it go, let it go
You’ll never see me cry
Let the storm rage on
The cold never bothered me anyway
Sorry anon, I wasn’t part of those who were able to hear the song, but I did find these :
Let it go, let it go
I’m one with the wind and sky
Let it go, let it go
You’ll never see me cry
Let the storm rage on
The cold never bothered me anyway
Which someone quoted in this podcast. (the Frozen part starts at 48:00, the song is mentioned at 52:50)
That’s all I’ve got for now!
After all of that, we got a quick glimpse at Disney’s new film, Frozen, their next CG animated project that’s loosely based on Hans Christian Anderson’s “The Snow Queen.” The musical stars Broadway legend Idina Menzel as Elsa, a queen in self-imposed exile, and Kristen Bell as her sister Anna, who, along with a mountain man named Kristoff, travels into the icy wilderness to track find her sister and bring her home. Bobby Lopez (Book of Mormon, Winnie the Pooh) and his wife Kristen are writing the songs for this movie, and along with Menzel’s talents, we’ll also be hearing Bell’s singing voice too. (The younger actress also got her start on Broadway.)

BREAKING NEWS! We’re excited to announce that Idina has been cast in Disney’s next animated feature film, Frozen. Based upon the Hans Christian Andersen fairy tale entitled “The Snow Queen,” Idina will voice the title character of the Snow Queen. “Veronica Mars” star Kristen Bell will also be voicing the other lead character. According to ENTERTAINMENT WEEKLY:
The Wicked Witch of Oz might be turning green with envy (if she wasn’t already, obviously). Idina Menzel, who won a Tony Award for originating the role of misunderstood Elphaba in Broadway’s Wicked, will be playing a different type of sorceress in Walt Disney Animation’s upcoming Frozen, loosely based on 1845′s The Snow Queen by Hans Christian Andersen.
Kristen Bell will costar as Anna, a young girl who ventures to find Menzel’s Snow Queen and end the perpetual winter that has fallen over their mythical kingdom, the studio announced today.
The movie, of course, will have a musical element, with original songs by Broadway’s Robert Lopez (a two-time Tony winner for Avenue Q and The Book of Mormon) and wife Kristen Anderson-Lopez (who worked with him on Disney’s 2011 Winnie the Pooh.)
Still uncast in the movie is the role of the leading man, Kristoff, a mountain climber who leads Anna on her quest through snowy peaks and dangerous cliffs to find the legendary Snow Queen.
The digitally animated feature will open in November 2013 and is being directed by Chris Buck (Tarzan, Surf’s Up) and produced by Peter Del Vecho (Winnie the Pooh, The Princess and the Frog).
Andersen’s writings, of course, provided source material for the movie that led to Walt Disney Animation’s renaissance in 1989 — The Little Mermaid, another loose adaptation of a classic tale whose popularity today is testament to its, let’s say, legs.
Walt Disney Animation Studios presents an epic tale of adventure and comedy in Frozen a computer-animated feature film slated for the big screen in November 2013. Directed by Chris Buck (Tarzan, Surf’s Up) and produced by Peter Del Vecho (Winnie the Pooh, The Princess and the Frog), Frozen features the vocal talents of film/TV/stage star Kristen Bell as Anna, a young dreamer about to take the adventure of a lifetime, and Tony Award-winning actress Idina Menzel as Elsa the Snow Queen. The movie will feature original songs by Broadway greats Robert Lopez and Kristen Anderson-Lopez.
In Frozen, a prophecy traps a kingdom in eternal winter, so Anna (voice of Bell) must team up with Kristoff, a daring mountain man, on the grandest of journeys to find the Snow Queen (voice of Menzel) and put an end to the icy spell. Encountering Everest-like extremes, mystical creatures and magic at every turn, Anna and Kristoff battle the elements in a race to save the kingdom from destruction.
