As usual, you've posed a problem and pretty well left little else to say. My reaction is this: If I'm working at the Joseph Campbell and Carl Jung level, I'm being far too cerebral. All I need from Campbell is a structure found in Vogler, etc. All I need from Jung is one of many characterization methods based on his work--the MORE method, enneagrams, etc. Defining structure and characters can be done off-line before writing scenes. For the latter, I shift gears and get into the characters' minds--feeling, wants, needs drive the writing from this point on. Writing for film is a little like playing tennis: there are a dozen or more things you have to do right and you have to do them all at the same time. Only a very experienced player (writer) can do this on the fly, in realtime. Luckily, unlike tennis, writers can freeze the ball at any point and check stuff. For this, I use my secret weapon: punchlists.

Thanks for that, Jeff. I agree: We can get too bogged down in theory. That's why I suggest no matter what we study and how much we know, when we actually sit down to write pages, we set that stuff aside... and feel our way through each scene. Would you mind elaborating more about 'punchlists'? I'm sure others would like to know more about that. Thanks!
