HOW TO WRITE SCRIPTS FROM REAL LIFE STORIES
Stories based on real life have a “pre-built” story and make some of the most compelling films around.
In one way this can make a screenwriters job easier, and in another, make it far harder. First you should read Technical Writing, watch and research other real life stories that have been adapted into books, movies, or plays. Real life stories have a completely different feel to them vs. a fictional story.
Make sure you find the real life story of the main character personally interesting before agreeing to the project. If you are not personally moved and inspired by what this person went through, the script will not be the best it can be and your main characters story will not get the attention it deserves.
So you like the story, no wait, you love the story. Well then, write down the key points that make you love it.
