Throughout the guide we've mentioned that you should control where your pages break. Don't let Scene Description or Dialogue run from one page to the next. Always end a Scene Description with a full sentence and start a new block on the next page. Always complete a Dialogue Block or take the loss of space and move it onto the next page in full. If it is a very long passage of dialogue which has a logic spot to break it, you can use a (CONTINUED) though most screenwriters like to avoid this.
Some screenwriters control their page cutting by breaking the Blank Line rules. Very occasionally they will cheat and pull out a blank line to try to keep a piece of dialogue or description on a single page. You can get away with this when you have a widowed word on a line or when losing a blank line still leaves a slant break between left justified and right justified words. More often they will add extra blank lines to space their pages out. This is useful when you have a long piece of dialogue which is hard to break up. When you move it to the next page you have a lot of empty space on the bottom of the current page. You might like to space out the elements on the page to make the page fuller. But this still leaves a lot of white space on the page, leaving it easy to read.
But page cutting is also more format. Your script is being read. You have the opportunity to use the power of visual images to assist your storytelling. Whether it is pacing events or setting up a surprise, the medium can help you zing the message.
