Disney has released the first images from their upcoming animated film, Frozen.  The film features Kristen Bell as the voice of a young dreamer named Anna who teams up with Kristoff (Jonathan Groff), an extreme mountain man, to find her sister Elsa, the Queen of Arrendelle (Idina Menzel) who has accidentally trapped their kingdom in eternal winter.  Anna and Kristoff are joined on their journey by Kristoff's trusty reindeer Sven, and a talking snowman/comic-relief, Olaf (Josh Gad).  The film will also have a bit of a love triangle between Anna, Kristoff, and the dashing Prince Hans (Santino Fontana), but the story will focus more on the relationship between Anna and Elsa.  "That's such an important part of this,'' co-director Jennifer Lee tells USA Today.  "Two sisters torn apart by a big family secret."  Bell adds that Anna is "not a good fighter, she doesn't have good posture, she's not very elegant, and she's constantly putting her foot in her mouth.  But, Bell adds, "she's a good person and she's utterly determined."  That sounds a bit like Disney's Rapunzel, but I'm sure Anna will have her own personality, and I'm particularly interested to see how she relates to Elsa, since we haven't really seen that dynamic with a Disney princess before.

Here's the official synopsis for Frozen:

When a prophecy traps a kingdom in eternal winter, Anna (voice of Kristen Bell), a fearless optimist, teams up with extreme mountain man Kristoff (voice of Jonathan Groff) and his sidekick reindeer Sven on an epic journey to find Anna’s sister Elsa (voice of Idina Menzel), the Snow Queen, and put an end to her icy spell. Encountering mystical trolls, an amazing and comedic snowman named Olaf, Everest-like conditions and magic at every turn, Anna and Kristoff battle the elements in a race to save the kingdom from destruction.
