Nausicaä of the Valley of the Wind

Very early film by anime master Hayao Miyazaki, who used the proceeds to found his famous Studio Ghibli. In a post-apocalyptic future, the world has fallen apart into several kingdoms, but is still threatened by ecological damage. A pacifist princess willy-nilly gets involved in the conflict, but possesses enough fighting spirit to enter the battle for the cause. Miyazaki adapted his own manga series in what in many respects is a precursor of his eulogised Princess Mononoke, containing all the typical elements: a fearless heroine, thrilling flying scenes, gorgeous visual designs, an ecological message, plus top-level animation.
