Sorry to say, I think the film's total bullshit.
First of all, it assumes the people who wrote the Bible had some knowledge of astrological signs and put it together accordingly, which I highly doubt on both scores. Also, there's simply no way that 9-11 was staged. Sure, there are some unexplainable things, but, as Noam Chomsky pointed out, in many controlled experiments that any scientist can conduct in the lab, there are plenty of events that occur that were not predicted and cannot be explained. The melting of the steel in the twin towers can probably fall under that blanket term 'unexplained phenomena.' Doesn't mean it was a put-up job.
