Writing Movies for Fun and Profit: How We Made a Billion Dollars at the Box Office and You Can, Too!, Garant & Lennon. Non-Fiction. This is a ruthlessly practical guide to selling screenplays to Hollywood studios. It also provides appalling and entertaining insight into what is required of a writer in order to make a living doing that. If you are at all interested in the business of writing Hollywood studio movies, I encourage you to read this book. Even if you’re not, it’s probably worth a look.
