Its pure brilliance, and so helpful for anyone like myself who aspires to work in film someday. It gives a clear and detailed description of all the main playing jobs of the industry from someone who actually knows what they're talking about. Not only is it informative, but its actually pretty funny in parts and a good read if nothing else. I've read the whole thing through a few times and I'm very grateful for the time Oliver Stapleton put into it. Thanks!
