If you've never made a short film before and haven't a clue how to start then beware that this book does not offer a practical, step-by-step guide to getting your film made. It's a useful resource for short-filmakers that have already made at least one film or at least know the basics, which this book skips over.
For example, the book provides a sample press-kit for if ever you put your film into a festival, but it doesn't give you more basic essentials such a call sheet or a production schedule which you will need to get your film made.
On the plus side, this books is still a fascinating read for anyone interested in film-making and I couldn't put it down once I started. The sample scripts and interviews with film-makers were especially well-selected.
I would definitely recommend this book, but if you have never made a short film before then you may need to do some more research on top of what this book gives you.
