Whatever you do, don’t be too protective of your idea or script. Don’t worry about bad guys in Hollywood stealing your inimitable idea and sailing to the Maldives. The odds of that actually happening are extraordinarily limited, but the odds of a producer thinking you’re paranoid and running like blazes are quite real.
So, quick advice: tell your story to anyone who’ll listen. Saying it out loud will help. A ton.
Once upon a time, I was directing a short film and, the day of the last shoot, was having breakfast with a friend. He asked me what my story was about and, not being paranoid, I told him.
As I described the climactic confrontation between the heroine and her oppressive mother, I realized, to my shock, dismay, consternation, horror and amazement! that I had neglected to include that oh-so-critical final confrontation in the script and, therefore, it was not on the shot list! and was not going to show up in the editing room! ARRGGHHHH!!!
I quickly wrote a titanic battle between daughter and mother on the steps leading to the girl’s bedroom. My image was two Arnold Schwarzenegger types with broadswords hacking their way up and down blood-soaked stairs until finally, the exhausted daughter slices off her mother’s head and is victorious.
It was a useful way to write an argument.
Which brings me to a couple of thoughts…
1.) However you define “mortal combat”, it has to happen at the climax between your hero and opponent. That face off must be as intense as your story’s tone will allow, yet still be believable.
But you have to have it!
We waited the entire movie to get here! Don’t be stupid like I was and forget that, at the end, you gotta have a slugfest.
Happily for me, both actors were superb and the mother cried when her daughter announced she was going to live her life free from her mother’s shackles. That’s not what she said, but you get the point.
2.) Telling my story out loud saved the movie. Because I was speaking, my mind operated in a different way than had I been writing. Jiggling your brain around will work miracles for your story.
