I look forward to seeing that documentary. I am constantly amazed at how many people are still hostile to any "doubts" about the official story of 9.11. There is so much information out there, documentaries, videos and books. I can definitely recommend David Ray Griffin's book (I think it is his second and I cannot remember the title, I cannot look it up as I had to give it back to the owner of the book).
However, even if video evidence of people wiring the buildings with explosives or the skeletal remains of the passengers in the aircraft that were said to have hit the buildings, was miraculously discovered and publicised, there is still an incredible number of people who just wouldn't believe that this was anything but exactly what the "official story" said. I am pretty convinced of that now.
Good that another film is to be made. But A&E for 9.11 truth have already said so much that cannot be disputed, a lot of people didn't take any notice before, they probably won't this time either.
