Zeitgeist is perhaps the most awesome documentary film I´ve ever seen. Though I´ve only seen two parts of the first movie, I´m very looking forward to see the other parts of it.
Zeitgeist tells quite a few stuff about Christianity and how it´s just a "parody" of the ancient Egyptian religion, but also mentions the beyond obvious similiarities in them, and other religions and how they got their basics from, guess what, ASTROLOGY.
The second part tells stuff about the 9/11 incident, the so called "Terror attack on the WTC towers". It appears that it was actually a job from the inside, not any terrorist attack! But I won´t tell more spoilers, feel free to find the whole movie at
