How to Write a Script

Part 1 of 5: Learning Scripting Conventions
1. Have a title page. Your script will need a title page. This will include the title and your name, but it will also include your contact information and your agent's information (if you have an agent).
2. Use the correct font, margins and breaks. You will need to use Courier font (typewriter font) (12 point) when writing your script. This will give it a more professional appearance but it is also key for making it easier to read. Similarly, you should use the correct indentations for each part of your script, as it will help the reader differentiate between dialogue, scene description, etc.
3. Give helpful details about the setting and characters. Use slug lines before each scene. These say whether the action is taking place inside or outside, what the location is, and if it is day or night. A character's name should go in all caps above or next to their dialogue (depending on what you're writing for). You can also put instructions, such as pauses, in parentheses.
4. Use the correct formatting for your intended method of presentation. If you want to write a movie script, then you will have to write your script in that format. If you want to write a play script, then you will have to write your script in that format. While they are largely similar, there are distinct differences and learning them all can take time. Read lots of scripts in your intended medium to see how the pros do it.
5. Make sure you haven't written too much. Scripts usually last about one minute per page, though there is certainly some wiggle room.[3] Scripts are not like books in that word counts. It is a definitive way to gauge length.
Part 2 of 5: Developing Your Story
1. Formulate a premise. Write a short sentence or phrase of the fundamental concept which drives the plot. This can be something which is the message or idea behind your story, an extremely short plot idea, or something else to give you a goal and unifying idea to work toward.
2. Create an outline or treatment. Before you begin actually writing dialog and script, it might help to create a basic road-map/story of what will happen in your story so you don't get sidetracked and can work out any plot holes or kinks. Sketch out a general plan and envision how events will unfold. This should be told in the third-person.
3. Flesh out your story. Write the entire premise of the play, movie, etc. with lots of details and ideas, paying no mind to style, format, repetition, or anything else that gets in the way of your creative flow. Your finished product should cover the plot, personalities, relationships, character arcs, and a larger point to the story. Sometimes, drawings or diagrams may be used as a temporary storyboard to show to other persons to demonstrate facets of your plot and characters, etc.
4. Trim the story down. Now that you have everything on paper, look for dead weight, weak links, irrelevant details, over-explaining, sidetracking, elements that drag, and anything else that weakens the overall trajectory. Be harsh; just because you fell in love with something you worked on in the exploratory phase doesn’t mean it should survive the revision phase.
Part 3 of 5: Improving Your Script
1. Research after writing your first draft. Watch plays, tv shows, and movies which are similar to the work you’ve just written. Examine your own work in comparison to these others. Do you fall into to many tropes? Is your story over done? See if you can find ways to distinguish yourself from these works.
2. Simplify your writing. You don’t need overly fancy dialogue or crazy scenes to keep your audience engaged. Much like with writing a book, our work shines the most when we are showing, not telling. Make your character’s choices speak for them and put more meaning into what they don’t say than what they do
3. Write the plot in script format. The exact format will vary depending on whether you’re writing for theater, TV, or the silver screen – and in what country. (For example, the American TV industry’s standard script format is modeled on the business plan.) Use proper headers to introduce scenes, identify each speaker, and so on; many production companies won’t even look at a script if it isn’t properly formatted.
4. Maintain your style. Remember, scripts are all about action and dialog. Make sure your characters speak realistically, and try not to mix styles of speech and vocabulary too much unless you are going for a certain effect.

Part 4 of 5: Engaging Your Audience

1. Set the scene. Don't forget to include important details such as time of day, setting, and actions of the characters in the scene. These are nearly as important as the dialog that occurs
2. Describe action only briefly. Provide a sense of what’s happening on screen, but leave it to the director to fill in the details. Writing out all of the action is not the writer’s job. Trying to include too much of this will only leave you disappointed when things are changed.
3. Spend a lot of time working on your dialogue. Dialogue will make or break your characters and their relationships. What’s worse, dialogue is extremely difficult for most people to write. To get your bearings, write down or record real conversations to see how people really speak and which expressions they use.

Part 5 of 5: Finalizing Your Script

1. Edit your work. Polish it, but don't be a perfectionist; work toward perfection, not to it.
2. Show your finished work to people whose opinion you respect. Choose people who not only come from different backgrounds and have varied personal tastes, but are also willing to provide honest feedback.
3. Revise your work as many times as necessary. Painful as it may be, you’ll be glad when you’re finally able to convey your vision.
