The only September 11th film I will recommend to the general audience is 9/11 Press For Truth.

The website for the film is http://911pressfortruth.com/.

This film does not speculate about the facts. It presents them, as chronicled in Paul Thompson's Compete 9/11 Timeline. It shows the Bush regime's opposition to a valid investigation every step of the way, and includes the Pakistani ISI funiding of Mohamed Atta, as well as the two deliberate stand downs where Al Qaeda forces were allowed to escape in Afghanistan.
