Looking at all of Miyazaki's animated films, it is not difficult to find that "flying" is his eternal theme. In this film, he even moved the stage to a "Castle in the Sky"-Laputa, a city in the sky. This is an aerial city powered by flying rocks of anti-gravity device. Full of strong social consciousness and humanistic care, Hayao Miyazaki tries to inquire into the root cause of the loss of civilization, insinuates the existing shortcomings of human civilization, and explores the philosophical propositions of how civilization can survive and develop. And all of this is manifested through the rise and fall of Laputa, the fictional city of the sky.
In the film, Laputa is already a deserted city when it appears. People can only imagine its prosperity in the past through huge flying rocks, countless robots, and piles of treasures. Miyazaki obviously has no intention of focusing on introducing the audience to the process of the emergence and development of Laputa civilization. He just used the final destruction of this once extremely prosperous civilization to strongly shock and impact the hearts of every audience, so as to question the masses in modern society, and finally to think about the practical problem of where human civilization should develop.
