Screen writer, you are going to be responsible for providing just enough detail to the action so that the reader can visualize it in the film screen of their mind. The one thing about detail that you have to be careful about is not to put so much detail on how the character is saying something or how they're doing something because that can be construed the reader, especially directors and the actors as screenwriter. Basically, directing on the page detail is something that you again want to use just enough amounts to give just enough of a complete picture of what's going on.
