The title of the review I read of Cohen's Screen Plays was titled "How Does this Crap Get Made?" and I thought "HA! This is a question I ask myself ALL THE TIME." So, thanks to the joys of ILL, I got to find out. Cohen, a writer turned journalist for Variety and Script (the introductory story about his own foray into writing Star Trek episodes sets the story perfectly) takes a look at how 25 movies went from first draft to the actual movie. He writes about big hits and Oscar winners(Gladiator, The Aviator, Erin Brokovich, Witness), indies (Eternal Sunshine of the Spotless Mind, Lost in Translation) and movies that just didn't turn out right, often despite A list casts (Evening - Meryl Streep, Glenn Close, Vanessa Redgrave, Claire Danes, Toni Collette).
Each chapter is relatively short, and Cohen interviews each of the writers from the perspective of someone who is a writer, a journalist, and movie fan. He's a good writer himself, and uses each film to illustrate something new about screenwriting and how movies get made. It's filled with insider drama -writers getting hired, fired, and rehired, scripts being rewritten and then changed back to the original versions, directors and A list actors being "attached," and screenplays changing hands as studio fortunes rise and fall.
Most interesting chapters? The ones on American Beauty (minor changes suggested to writer Allan Ball changed the whole tone of the film, and for the better), My Best Friend's Wedding (more anti-Hollywood ending than I'd ever considered) and Pay it Forward (because, really, how did that crap get made?).
