Network is an unparalleled skewering of American television and society. It was released in 1976, and although slight aspects of the film seem a little dated today, the film’s heart still beats strongly, and says a lot about today’s television that Paddy Chayefsky could only imagine . . . and successfully, I might add.
The New York Times has an article all about Chayefsky’s preliminary notes for Network and they give an amazing insight to a writer’s creative process. I don’t know if this material is enough to make a book out of, but I’d love to read it.
