Not Always in the Script
The most interesting thing for me was to hear how much the film changed from script to screen and exactly how those changes came about. They had a whole team assembled right from the beginning including Editor/Composer John Ottman. I get the impression it was basically one big discussion between everyone, with no one being particularly egotistical, which is quite unusual in it's on right.
It's very revealing about how collaborative filmmaking is, and how much of a crazy amount of work and revision goes into getting something good.
I wish more aspiring filmmakers as well as actors could have seen it. There is soooo much that goes into making a film, and many times it is very difficult to get everyone on the same page, the Director, the Actors, the Cameraman. The Director has a pretty good idea of what he/she wants the finished copy/work to look like, and he tries to convey that to all those involved. The writer has the idea and the vision, the director must put it all together, with his personal input to make it watchable and of course marketable. That is their job.
