A couple of generations ago, the movie industry ran more or less on gut instinct--film schools, audience research departments and seminars on screenwriting were not yet de rigueur . Today the standard is the analytical approach, intended to demystify filmmaking and guarantee success (or at least minimize failure). The trouble with this method is that nobody knows how to do it--they just think they do--and films are made based on models of predictability rather than the merits of the script. This insider's look at the craft and business of screenwriting explodes some of the popular myths about writing for the movies, demonstrating how little relevance the rules have to actual filmmaking. With long experience in film and television, the author provides insightful how- not -to analyses, with commentary by such industry veterans as Josh Sapan (CEO of AMC Networks), bestselling author Adriana Trigiani and Oscar-nominated screenwriter Nicholas Pileggi ( Goodfellas ).
