Do not use the format common for stage plays. If you are not familiar with standard television script format, buy yourself a book on script writing or find a copy of an actual script. For more information on this, visit the format page. Star Trek spec scripts need to be 55 to 65 pages in length. A common rule of thumb says 1 script page equals approximately 1 minute on the television screen.
Script timing is a very accurate science.
Please do not apply your own theory. Again, I have more on this in the format section. Again, format is the key. It is a very good idea to use the following guidelines as a checklist prior to submitting your script. There is no limit on the number of scripts an agent may submit for you.
