How I Wrote the Screenplay for “Arrival” and What I Learned Doing It
This is a really great analysis of how hard it is to write a really good screenplay.  As an occasional screenwriter myself, it's always frustrating when producers and directors repeatedly want to dumb down a script or "make it more exciting" to keep ADD audiences engaged.  It's understandable, of course - traditional genre movies for the masses make more money, and entertainment is a business.  But the fact that Eric Heisserer was able to keep everything in his screenplay at the intellectual and emotional level that he did really says something about the passion he had for the source material.Also, the note about the limitations of screenwriting software is spot on.  The fact that Final Draft costs $250 and can't even support image embedding is ridiculous.
