That's a variation of the old "put the manuscript in a drawer for two weeks" method, after which you go back into the drawer and read it with fresh eyes. It's amazing how a little tincture of time can cause those less-than-ideal passages to jump right out at you.

One of my favorite book recommendations from you, Scott, was Craft of the Screenwriter by John Brady. One of the screenwriters shared that he copied and pasted the text elsewhere, so would look different, forcing a fresh read. While folks who write fast might not need the new perspective (read today that Christopher Hitchens writes 250 words every 15 minutes when he has a column due), for a slowpoke like me, who rereads so often, that has been useful advice.

@CJ: I'm a big proponent of the two week away approach. In fact in the SMC rewrite workshop, that is our standard operating procedure. You're right. Amazing how just a little time away from a script and hanging out in that story universe can give a writer a new / fresh set of eyes.

@Atlanta: That book edited by Brady was one of the very first I bought about screenwriting. Still have my original copy, all dog-eared and underlined. Chayefsky, Goldman, Lehman, Schrader, Simon, Towne. Masters all.
