Loose Change is a series of films released between 2005 and 2009 which argue that the September 11, 2001, attacks were planned and conducted by elements within the United States government, and base the claims on perceived anomalies in the historical record of the attacks. The films were written and directed by Dylan Avery and produced by Korey Rowe, Jason Bermas and Matthew Brown.
The original 2005 film was edited and re-released as Loose Change: 2nd Edition (2006), and then subsequently edited a third time for the 2nd Edition Recut (2007), each time to tighten the focus on certain key areas and to correct some inaccurate claims and remove copyrighted material. Loose Change: Final Cut, deemed "the third and final release of this documentary series" was released on DVD and Web-streaming format on November 11, 2007.
Another version of the film, Loose Change 9/11: An American Coup, released on September 22, 2009, is narrated by Daniel Sunjata and distributed by Microcinema International.
Coverage for the film increased in 2006 with the recut release having airings on U.S. and European television stations and over 4 million views online in four months, leading Vanity Fair to say it could be the first internet blockbuster. Loose Change asserts that the usual account of the Pentagon attack, World Trade Center collapse and United 93 phone calls and crash is implausible and instead suggests the 9/11 attacks were a false flag operation. The film's main claims have been refuted by journalists, independent researchers, and prominent members of the scientific and engineering community.
