Sailor Venus: (about the Snow Dancer) She's no Venus de Milo!
Unlike the other two movies, this movie is actually based on the manga. Volume 11 of the manga features a side story about Princess Kaguya, which was adapted into this movie.
On the DVD, there is a hidden Easter Egg; Go to the Extras Menu, highlight the Transformations option, but do not hit enter. Hit the left button once, and then Luna's crescent will be highlighted, and now you can access Luna's transformation scene.
Princess Kaguya is the name of the principle character in one of Japan's oldest tales called "Taketori-monogatari," otherwise known as "The Tale of the Bamboo Cutter." According to the tale, a bamboo cutter finds an infant, with the elegance of a princess, inside the stem of bamboo. He takes her home and she grows into a fine maiden who is admired by many. One day she tells the bamboo that she must return to the moon, a place that's her original home. She leaves and forever after, the bamboo is sacred.
This legend is included in the DVD extras.
