This flowchart breakdown of the traitional James Bond movie structure is quite good. I like this sort of graphical representation of plot structure and I wish it use was adopted in more game products. If I was a better person when it came to game prep I'd do that sort of thing more often.
It's by Charlie Stross, whose
Family Trade novels I should read sometime. His Cthulu-spy-geekulfillment novel was a fun read (not great but fun).
