I just saw an american friend that watched Fahrenheit 9/11 at Cannes Festival yesterday.
There was a 20 minutes standing ovation at the end of the film !!
He says the movie is not 100% convincing but it's still a bomb and he believes that, if the movie is distibuted in the US before the elections, there's no way Bush is re-elected.
The interesting fact is that i know my friend for a long time and he told me that even though he never liked Michael Moore ( we had severe arguments about that

), he cannot vote for Bush again after seeing that flick !
