Write your story from beginning to end in the present as though it is happening now and you are the witness. This is what is called a story treatment. Let each paragraph just highlight the scene. Only use dialogue when it is absolutely necessary. You’ll have plenty of time for that later when you craft your script. Right now, the big thing is to get your idea on paper. It might be just a few pages or it may be 26 pages. Whatever it takes to properly and completely tell the story is ok. It’s your story.
If you have chosen the present as the time frame for your first project, you have just saved a ton of expense and aggravation. This means any current style of dress works and is readily found if you don’t already own the wardrobe needed for a particular scene. The same goes for dressing your street scenes. Any car parked along the street or driving by is appropriate. So if you don’t have a budget, see if your story works in the present.
I prefer the lengthy detailed treatments. I want to create a flow to the story’s events that establishes feelings that I want to expand in the visual presentation. If it is clear to me now, it will carry over in the construction of our next step, the screenplay.
