Plans to make a movie based on "The Snow Queen" were started in the 1940's. The writers were not sure how its story could go and so the movie could not be made. Later, in 2011, the writers finally found a story to use for the movie and the production team began making the movie, naming it "Frozen". The plans said that "Frozen" would be hand-drawn, but the team later decided to use computer animation. It took only two years to make "Frozen", which was a very fast production time for a computer-animated movie.
