Write your movie script according to the standards of a screenplay format. Movie scripts are different from literature because they need to be translated to the screen, which means a director must be able to read the script and visualize it easily. According to Virginia Commonwealth University's "Screenplay Manuscript Format," you need to set the correct margins for the top, bottom, dialogue, descriptions and character stage directions. Correct formatting makes your movie script easy for people to read, understand and follow. If a movie script is not properly formatted, it is more likely to be thrown away. If you take a few extra minutes to get the formatting right, you can make a big difference in whether people take you seriously.
Don't go too long with your script length. Increasing the length of your screenplays increases the chances of having your script thrown away. Make sure there is no unnecessary information in your movie script. According to Screenwriting's article "Spec Screenplay Page Properties and Script Length," the average screenplay is around 95 to 125 pages. Keeping the length around 120 pages is ideal for a full-length movie, although it can be shorter too.
Make sure the first 15 pages of your movie script are captivating. The first 15 minutes of a film are important because they let the audience establish whether your movie script is worth reading. Make something significant happen by developing an important incident that draws people into the script. Get them to care about what happens next by creating empathetic characters. Developing the central issue of your screenplay early on will keep your readers' attention and have them turning the pages.
