A screenplay… much like your life has a beginning, a middle and an end. When I write a screenplay the first thing I try and do is come up with my characters. I try to imagine them as real people, because I think of real people as stories. A screenplay is really just an intersection of stories (peoples lives) put together to tell a bigger story.
The hardest part of a screenplay is the middle act… which is probably the most difficult part of our lives to write also… especially if we are trying to live a great story. In early drafts of most film stories, one of the most commonly found problems is that the main character is too passive. Things just happen to them, they never force the issues, they don’t fight enough to achieve their goal.
