This was one of my favorite scenes to board on Rise of the Guardians. I just put the whole scene on my website. In the end this version was to ambitious for the final film. But there are some things that stuck. Originally Bunny had a more mechanical warren similar to the movie Hop or Charlie and the Chocolate factory. We wanted to stay away from anything mechanical and make it feel like a natural tribal cycle of nature. Everywhere Bunny landed or touched blossomed with life. Some moments stuck through to the end and other were too expensive. The process of the egg coloration was developed in this version with the pollen, vines and rivers coloring the eggs. A few things that wish we could have had in the final version were North riding a reindeer like a cowboy, giant bioluminescent danelion seeds, egg timer and an avalanche of eggs. But the movie wasn’t about bunny so the warren scene was pared back significantly for the final film.
