Disney has been working on Snow Queen-based-fairytale ‘toon Frozen for so long now, we saw concept art back when we visited the company for The Princess And The Frog. It has been going through quite the development process, but now the Mouse House has released a new piece of art from the movie to EW and you can check it out below.

Frozen, which hits our screens next year, stars Kristen Bell and Idina Menzel (or their voices, both spoken and singing) in a mythical tale of two sisters. Kind-hearted Anna (Bell) will have to go on a dangerous quest to track down frostier Elsa (Menzel), who is causing their land to suffer through a perpetual winter.

Anna sets out with cliffhanging adventurer Kristoff (Jonathan Groff had been rumoured for his voice, but Disney has not confirmed his involvement) on a dangerous mission in the chilly, Scandinavian-inspired landscape.

“We wanted to push it to the extreme,” says co-director (and Wreck-It Ralph screenwriter) Jennifer Lee. “The unnatural quality of the ice emphasises [that] this is not, you know, sky-made ice, but ice made by someone.”

And while it’s tough to research he magical ability to create strange snow and ice, it was easier to get a bead on sibling issues, especially after hosting a “Sibling Summit” for the filmmaking team that brought in their families to talk relationships and issues. “We got a ton of information from that”, says her colleague Chris Buck, “and it kind of grounds these characters in believability in magical and unbelievable world”.
