Nausicaa

The second time watching the anime, there are quite a few details I that enjoy to have noticed. The color blue, as we can tell from the legend of the messiah to the "calm" eye color of the ohmu, is an all important theme in Nausicaa. However, those are not the only moments of the film when the color helps to construct the narrative and becomes a central plot device. Even from the very start, blue is immediately made crucial to the plot and obviously important to the audience. As we see Nausicaa gliding through the air on her glider and then disembarking and entering the cave in the opening scene, the blue dress that the princess wears camouflages her to the background of the cave wall as well as the open sky. This suggests that the princess has an innate affinity with nature and the open forest, both of which are shunned by the rest of the world for their poison.
In fact, one can even go as far as saying that Nausicaa belongs to the "wild" more than she belongs to the civilized environment of human society. This view is further supported when the audience sees the frustration and anger that surface from within Nausicaa when she is constrained to civilization and her subsequent desire to return to the wild. We see these with the death of Nausicaa's father and Yupa's discovery of her underground laboratory that serves a refuge for Nausicaa in her times of distress. No scene is more obvious, however, than the one that shows Nausicaa struggling against the soldiers of Pejite and crying, "Let my fly!" as she attempts to fly back to warn her people of the ohmu invasion. Beside the obvious intent of getting back on her glider, the quote may well have revealed a sub-conscious longing to fly forever and escape from the death and fighting among humans.
One more comment on Nausicaa's flying- her glider, when looked from afar, looks very much like a bird and I believe it to be far from unintentional on the part of Miyazaki- she is meant to be a bird at heart.

A few other things which grabbed my attention while watching the film, but may have not had important consequences in the film. They are the eerie resemblance of Lord Yupa's arrival in the valley of the wind to the arrival of Gandalf in the Shire in the beginning of The Fellowship of the Ring, and the one and only mention of "God" when Nausicaa prays for the safety of the valley (this surprised me as there is no blatant religious overtone whatsoever in any other part of the film).
