Sorry Andrew, YOU COULD NOT BE FAR FORM THE TRUTH!!
Screening UNFINISHED material has everything to do with it!!
Of course not just about that, but it does have all to do with it.
Too many times in my 22 years in Hollywood I have seen this bring projects down, in both Motion projects as well as in Photography.
I bring any one to challenge my arguments with real facts, I have them, I have been there so many time I can't count them all, and all had the same results... failure!!
Executives and Theaters owners or Press, don't know shit about what PHOTOSHOP is or any POST program or FX for Motion Picture is, so you can waist all the time you want telling them... Oh you see this big wrinkle under her eye, well don't worry I'l take care of it in Photoshop, oh and that blown out highlights on her forehead, that too don't worry I'll take care of that also in Photoshop, and so on...
For motion Pictures even more complex...
So please Andrew with the out most respect you just simply are in no way qualified to tell me that I have no business saying what I have just said... BECAUSE I AM!!
