Hi, my name is Marco, I live in Buenos Aires, I'm a cinematographer and I want to tell you about what do you need to write a script. When you write a script you are writing about the live of a person and of course that person is not alone in the world. You have to know how work the psychology of your character and how that character make relationships with the other persons in your story. Is not only the relationship of that character with the other people, is the relationship with his environment and his world. Generally your characters will go to work in something, and there are a infinity of works that he can do it, so you have to know about how that particular work is done. And finally you need something that you want to tell, like talk about the love, justice, education or live. Now you can get all that stuff and mixing to make a interesting story! Well, thanks for you corrections, I hope don't have made too much errors. :)
