Zeitgeist: The Movie is a documentary created by Peter Joseph that came out in 2007. It has attracted a large underground following, largely on the internet. Though it's quite controversial, it has helped to popularize many "conspiracy theory" type beliefs. The film is divided into three parts. The first explores the origins of religion. According to Zeitgeist, the Christian religion is not original but borrows from earlier pagan myths. This part of the film was largely based on the book, The Christ Conspiracy: The Greatest Story Ever Sold, by Acharya S.
The second part of Zeitgeist deals with the events of September 11, 2001. The film expresses the view that the attacks were an inside job, perpetrated for the purpose of clamping down on civil liberties, launching unjust wars and economic profit. Much of the material in this part of the film is similar to other 9-11 conspiracy films such as Loose Change.
Evidence is presented that contradicts the mainstream view of 9/11, such as the fact that Building 7 collapsed even though it was never hit by a plane. Also addressed is the manner in which all of the buildings fell, which was more like a controlled demolition than what you would expect from the impact of planes.
Part three of Zeitgeist discusses the economic control of modern society. Specifically, it claims that international bankers have deliberately created a state of affairs where a tiny elite profits while the vast majority struggle and end up increasingly in debt. They do this largely by manipulating the currency through the privately owned Federal Reserve Bank.
The three parts of Zeitgeist, while dealing with separate topics, come together under one basic theme. The basic premise is that the majority of people are being manipulated by the government and mainstream media, and fooled into accepting a false view of religion, economics and history.
An updated sequel to Zeitgeist: The Movie was released in 2010.
