I have a very strong suspicion that as of this morning, the film does not exist...
I think "as of yesterday".
Officially, perhaps, but when you shoot for a movie, you make endless copies. If it was a digital shoot there are probably cached copies on various email servers.
Unless the film was insurance.
Moore could have been astute enough to film a cover story before sending Nick to Iraq to dig up dirt. All Moore would have to do is film some kind of bogus "interview" of Nick auditioning for the film. Then if he gets killed in Iraq while doing a group hug with al Quaeda terrorists, all Moore has to do is pull out the "audition" film. It would serve as a good cover story to explain any connections that may pop up between the two of them later.
What am I missing? A gross overestimation of Michael Moore's IQ level, I know...
