The screenplay you've pounded out on your trusty word processor is finished at last! Before the reader even looks at the title of your script, it must pass the "rifle test." The rifle test tells a professional in seconds whether the script is professionally written or not. Is the screenplay in the right format? Does it look like it was written by a professional screenwriter? Is the script vertical?

You must not be afraid to hack, chisel or cut-out ANYTHING that
does not serve to push the story forward. Sooner or later,
you'll write a scene that is just plain good. You're in love
again and all is right with the world. Finally, you conclude
that it doesn't serve the story as it should. You must get a
divorce and hack it out of the script.

Being "married" to your screenplay is asking for trouble. Get a divorce! Here are some practical how-to exercises you can use to find your objective view of your work and make your script better.
