Like every week we post a book review on a subject related to acting, health, personal growth or anything related to the showbiz industry. In this case its one of the Dummies ed. Books.
These books are simply wonderful. If I ever feel like I want to learn about a new subject I have no idea about or am overwhelmed, then I always turn to Dummies. They give you insight in a very reader-friendly manner, touching all subjects related to the topic at hand, providing you with any information you need. The Screenwriting for Dummies edition does just as any other Dummies book, and wonderfully explains the ins and outs of how to approach writing for TV, movies or plays. It provides tips, common used jargon from the industry, and plenty of clear examples. It will serve as the perfect go-to reference guide to start a new career in screenwriting. It is meant to be a springboard to then further expand if you want to master any aspect, not as an answer to the experts questions. As far as the tips on how to approach screenwriting from an actors point of view they don’t exactly dig into that, although it is mentioned in several chapters, that some of the best screenwriters have had atleast some experience as actors to gain insight on how to create characters. So maybe you would like to explore a different creative outlet? Remember tht Silverster Stallone wrote Rambo for himself when he couldn’t get cast in other movies. So, Is it worth reading? If you have any interest in the process of screenwriting or want a new creative outlet and are thinking of writing your next lead role yourself custom to you, then YES. If you want a good reference book on insight to a different aspect of this business YES. Otherwise simply from an actors standpoint, its not worth it.

I’m impressed by your writing. Are you a professional or just very knwoldgeaeble?
