Don’t watch this movie standing up. Or if you do, make sure you have a chair nearby to sit down in. Dylan Avery’s “Loose Change,” a documentary about 9/11, is sure to shock you enough to make you want a seat.

“Loose Change” centers around the idea that 9/11 was not planned by al-Qaida, but instead by our own government.

Radical? Yes, but it’s hard to walk away from this documentary without some new insight. There are several documentaries about 9/11 and the aftermath, but I’ve never seen one that has the effect Avery’s does.

Within the first five minutes, you’re already left reeling from the overwhelming amount of information presented on the screen. The film begins by offering numerous quotes saying opposing things about whether or not 9/11 was planned, one of which is Secretary of Defense Donald Rumsfield himself saying that there were “plenty of warnings.”

From there, it delves into various sketchy incidents in American history, from proposed staged terrorist acts to incite an invasion of Cuba in 1962, to Osama Bin Laden – supposedly wanted by the United States since 1998 – being treated in an American hospital in Dubai in July 2001, to chilling facts about stock exchanges only days before the attack. This timeline concludes with the day of the attack, Sept. 11, 2001.

Avery structures the rest of his film around interviews, quotes, eyewitness accounts, scientific evidence and a myriad of other options to suggest his claim. He begins with the Pentagon attack, the most suspicious of the plane crashes, and continues on to discuss the suspicions surrounding the twin towers, flight 93 and the hijackers. Every point he makes, he backs up with often unnerving evidence. The whole film is narrated by him, and though he adds personal twinges here and there, it is not enough to destroy his credibility.

Overall, Avery does a fantastic job of making a point that is chilling at best, and that left me stunned in my seat. Whether you believe it or not is up to you, but I suggest this film to everyone, if only to take into consideration.

The film can be seen on Google video under “top videos.” It lasts about one hour and 22 minutes.
