First pictures and trailer for Disney's Frozen: watch now

With Tangled and Wreck-It Ralp h , Disney have successfully steered their CGI course into witty, adventurous and decidedly Pixar-threatening waters.

So we're pretty excited for their latest original comedy adventure Frozen , and the first teaser trailer and beautiful pictures (scroll below) suggests they could have another hit on their hands.

The plot finds fearless optimist Anna (voiced by Kristen Bell) embarking on an epic journey to find her sister Elsa (voiced by Idina Menzel), whose icy powers have trapped the kingdom of Arendelle in eternal winter.

Along the way she teams up with rugged mountain main Kristoff (voiced by Jonathan Groff), his loyal reindeer Sven, and an inept/merrily oblivious snowman called Olaf.

Cue mystical trolls, Everest-like conditions and all manner of magic mayhem.

The teaser trailer below seems to introduce us to Olaf, and the endearingly dog-like Sven.

One thing we definitely know after watching the below?

We want a pet reindeer.

And check out the other images released with the trailer. Purty, non?

Frozen opens in the UK on 6 December 2013.
