Many people don't get what the supernatural events were about in this movie. It is normal because it contains elements of common themes of ghosts and ufo. However, it deals with neither. Many of the events of the film makes sense if you understand occult lore of the Middle East surrounding creatures known as the Djinn. Forget about the Aladdin version of the Djinn. Mythological and occult lore of the Djinn is entirely different. Djinn are said to be of fire that doesn't burn. That is an ancient reference to electricity or magnetism. The word jinn in Arabic has the linguistic meaning of 'invisible' and it also shares the same linguistic root as the word 'mad'. Let's take a closer look at the movie... 1) The man in the cave is actually a sorcerer. The beings he was communicating with are the djinn. They are invisible to the naked eye, but they registered on the solider's equipment. He provided them water that turned into sand. Djinn in ancient lore are able to materialize things ranging from food to gemstones. However, they eventually turn to dust. 2) Evil tribes of the djinn such as the Beni Ghilan (followers of al-Ghoul) are believed to consume dead human flesh. 3) Ancient records detailing djinn materialization talk about strange sounds like 'buzzing bees' before they appear. In this movie, it is the buzzing sound of a chopper. 4) Magnetic phenomena....there is a little known Arabic text called the Green Island dating back to medieval morocco. This book talks about a man who was kidnapped by the djinn and taken to a magical island. He was returned to his village many years later. He left behind a make-shift map trying to point out where this magical island was. Modern researchers of the story tried to correlate the map with modern geographic data. They discovered that the instructions placed it somewhere in the middle of the Bermuda triangle. The mountain range appears to be another secret home of the djinn and thus seem to reflect strange magnetic phenomena. 5) Weird lights...the same old occult texts when discussing djinn manifestation refer to lights that suddenly appear and shine upon the sorcerer from which emerge strange figures (the djinn). 6) Ending....djinn are reported to have strong telepathic abilities and to be very secretive of their reality. The film's ending is about a man whose brain was scrambled by the djinn after being touched on the forehead by one of them. He got too close and he was neutralized and left behind as an example... I don't claim to know exactly what the script writer intended with all of those references. I am making an educated guess here based on the similarities (coincidental or intended) between the events of the movie and the ancient mythological narrative.

这片子我给打五星。首先我是比较感兴趣远古外星人理论的。欧美很多科幻片剧情都是基于某种科学假说或者科学理论而设计拍摄的。所以想看懂这片子还是得对相关背景有一定了解。从几个点来大概说一下对电影的理解：在山洞的老人手中拿的小飞机是曾经在考古界比较轰动的黄金飞机，另外这个东西曾经在苏美尔文明研究中也出现过。导演大概想说明世界宗教同出一源。古代宗教记载的超自然神迹可能同出一源。水壶中的水变为沙，这个需要对宗教比较了解，新约中曾经有耶稣变水为酒的记载。导演大概是想通过借鉴这种记载来解释这种现象，也就是换成科幻的解释方法。石头上肢解的生物，这好像类似献祭，所不同的是人而不是牛羊。这说明搜索小队遇到的并不是宗教记载的那位神。最后男主浮空并出现在研究所，说明如果在古代他可能会受到膜拜，但是在今天科学至上的时代他这种表现就成为了研究对象。其实我感觉这部电影有一定的反战理念，大概是想通过电影告诉观众首先宗教又可能同源，只是在各国反映出的文化现象不同。应该求同存异。人类对这世界了解的还很少。个人理解电影想表达的大概就是这个意思。
