I came away from this respecting the documentarian, but not the players or director very much.
Director Moore came across as a rather nasty sort, prone to tantrums, and filling his speech with more pointless uses of the F-word than I have heard in many years. If you cut out the number of times he uses this word in the documentary, either as a verb, adjective, adverb, noun, or participle (and yes, he makes ample use of all of these grammatical forms of the word in question) he would actually have had very little to say. Hey, buddy, buy a dictionary or get one of those word-a-day calendars and add to your vocabulary! There's a whole language out there to be discovered.
I was reminded of the documentary that Woody Allen's character makes of Alan Alda's comedian character in the film "Crimes and Misdemeanors," in which Allen makes a warts-and-all film exposing the other side of his subject. If you've seen that film, you will know what I mean.
It was strange to me that so little time was spent with Dennis Quaid in the documentary. Was there a reason? I watched this documentary prior to watching the film, and I was convinced that I would not enjoy a film from this director. I was pleasantly surprised that Flight of the Phoenix was well acted and filmed, and a worthy successor to the original version of 1965.
