You probably saw David Mamet’s memo to the writing crew of The Unit last week, but I was socked in, and just got to it. This was the best advice, to my mind:
EVERY SCENE MUST BE DRAMATIC. THAT MEANS: THE MAIN CHARACTER MUST HAVE A SIMPLE, STRAIGHTFORWARD, PRESSING NEED WHICH IMPELS HIM OR HER TO SHOW UP IN THE SCENE.
THIS NEED IS WHY THEY CAME. IT IS WHAT THE SCENE IS ABOUT. THEIR ATTEMPT TO GET THIS NEED MET WILL LEAD, AT THE END OF THE SCENE,TO FAILURE – THIS IS HOW THE SCENE IS OVER. IT, THIS FAILURE, WILL, THEN, OF NECESSITY, PROPEL US INTO THE NEXT SCENE.
ALL THESE ATTEMPTS, TAKEN TOGETHER, WILL, OVER THE COURSE OF THE EPISODE, CONSTITUTE THE PLOT.
ANY SCENE, THUS, WHICH DOES NOT BOTH ADVANCE THE PLOT, AND STANDALONE (THAT IS, DRAMATICALLY, BY ITSELF, ON ITS OWN MERITS) IS EITHER SUPERFLUOUS, OR INCORRECTLY WRITTEN.
And, yes, the message is written in ALL CAPS.
