movie with a mysterious wall

A troubled rock star descends into madness in the midst of his physical and social isolation from everyone.

In a small fishing village, a gloomy middle school student named Kai meets a mermaid named Lu.

European mercenaries searching for black powder become embroiled in the defense of the Great Wall of China against a horde of monstrous creatures.

In 221 BC, Qin Shihuangdi conquered the rest of China. Qin's great accomplishments and also his serious faults are showed in this film. Qin adopted autocratic dictatorship and led a luxurious life: abolition of feudalism and the centralization of power in the form of a now-hereditary bureaucracy loyal to himself; burning books and burying scholars; the construction of a sumptuous palace for his concubines and also the Great Wall.

The action takes place in Siberia where a mysterious wall appears from time to time. Scientists are dispatched to study it and some of them believe that the wall is produced by some sort of alien intelligence, "the Martians", as they call them. The scientists attempt to communicate with the Wall, but all they experience in return are hallucinations about their past experiences. In those visions they are faced with some unresolved issues, repressed memories, and absurd dream-like situations. They meet people – messengers – from their past who reveal to them some simple truths about their own lives, which may be hard to accept, so they dismiss those messengers as the Martians and stubbornly continue attempting to "understand" the Mysterious Wall using their rational minds.

The wall man is a strange wall-dwelling creature that is neither human nor ghost.
