Berlin - Giulietto Chiesa, Italian film-maker and European parliamentary deputy whose dramatic 2007 documentary ZERO casts doubt on the official US version of the 9/11 terrorist attacks, feels an international tribunal could "establish the truth about the events."Chiesa was in Berlin at the weekend for a screening of his film which features, among others, novelist Gore Vidal and playwright Dario Fo as well as retired American professor of philosophy David Ray Griffin, who advances conspiracy theories that contradict mainstream accounts of events of 11 September, 2001.
Federal Aviation Administration controllers, US Air Force pilots, military commanders and physicists also appear in the critical documentary, which the director hopes will create "political awareness" of the "faulty" official investigation into the events by the 9/11 Commission.
"Some of the individuals appearing in the film are former FBI and CIA agents, people who have in a sense taken a very big risk in speaking out. I am very grateful to them because they have done a big job," said Chiesa.
"The film would not have been possible without them," he said, adding that ZERO had been seen in France and Belgium at individual screenings, and by more than 20,000 people in Italy. But so far has not gained a distributor in Europe.
Chiesa, one of Italy's most respected journalists and for more than 20 years a La Stampa foreign correspondent, told his Berlin audiencean 9/11 international tribunal could serve a useful purpose.
"If feelings were strong enough a positive result could be obtained, but it would not happen immediately. So far it's been the US administration that has won the information fight and obtained their result - unfortunately.
"Our task is to inform millions of people of the true situation. Everybody should be involved in this struggle with a tribunal or commission helping once we win approval for the idea," he said.
Interviewed by Deutsche Presse-Agentur dpa, Chiesa said Russian television is to give prime time airing to his film on the eve of this week's seventh anniversary of the attacks in New York and Washington.
"That means that some 30 million Russian citizens will learn the truth about what happened, which is a very big result for me."
Chiesa, whose documentary was first screened to a large German audience at the Goethe Institute in Munich in May, was clearly delighted at his reception in Berlin. "It's important that so many people have shown up," he said.
One of a panel of six experts debating the 9/11 topic in Berlin, Chiesa said he was eager for his film to gain more public support and become a "multiplicator" across Germany. "If that happens it means we are making politics in the right sense of the word."
Andreas von Buelow, a controversial former German Minister of Technology, and ex-State Secretary in the Defence Ministry, was another of the Berlin participants who said further investigation was needed into 9/11.
