For those who don’t already know, Frozen is Disney’s latest computer animated musical fantasy-comedy film that’s loosely inspired by Hans Christian Andersen’s fairy tale The Snow Queen, it is the 53rd animated feature in the Walt Disney Animated Classics series. The film’s animators visited an Ice Hotel in Quebec, Canada to study how light reflects and refracts on snow and ice. For the film’s setting, the animators used the landscape of Norway and the feel of the winter season of Wyoming for inspiration.
Peter Del Vecho explained that “the title Frozen came up independently of the title Tangled. It’s because, to us, it represents the movie. Frozen plays on the level of ice and snow but also the frozen relationship, the frozen heart that has to be thawed. We don’t think of comparisons between Tangled and Frozen, though.” He also mentioned that the film will still retain its original title, The Snow Queen, in some foreign countries: “because that just resonated stronger in some countries than Frozen. Maybe there’s a richness to The Snow Queen in the country’s heritage and they just wanted to emphasize that.
