As I look at movie's made by big studios or short films made by my friends or other indie film maker's; I see that your script is the MOST IMPORTANT part of the film or short.
I just recently watched the first Transformer movie. Michael Bay can make movies seem so real with modern technology, CGI, and special effects. Watching it makes you get pulsed as the massive transforming robots slam into each other, transform, and explode through buildings. Wide sweeping panoramic shots bring the epic battles close in and we are entranced by the massive battles.
The reason is simple: the script. The script is where the plot is formed and the characters are brought alive from the text on paper. When the script is strong the movie is strong.
The script is 80% of the movie. It doesn't matter how much special effects, great acting, sound quality, music, world class director's you have without the script your movie will not be a great movie.
This is no less true for a short film. Even if it's a silent film, your script will outline what will happen and if your script is no good, your movie is on the fast track to cheesedom or boredom.
So what is a good script? How is a good script fashioned? Isaac Botkin says in his book(which I STRONGLY recommend)
A flawed but sympathetic protagonist
summons moral courage to face and then overcome
increasingly difficult, seemingly insurmountable moral tests to achieve a compelling desire.
The best movies you've ever seen follow this structure. It's not a formula, its a form. This particular structure is brilliantly complimentary to the Christian worldview because the protagonist is a hero. This structure can illustrate the truth. It can teach moral authority. It can clarify ethics. It can elucidate the meaning of moral courage and can explain the applicability of biblical wisdom. It can show the world what masculinity is. It can show the beauty of manners and family life. It can tell the truth about evil and show the cast difference bad character. It can pit evil against good. It can criticize evil instead of good.Your script must not just be a good story in the sense of story itself it must (if you call yourself a Christian film maker) proclaim God's truth to all men. Mark 16:15 says
And he said to them, "Go into all the world and proclaim the gospel to the whole creation.If we are Christian film makers our scripts must not only be good scripts but they need to cry out the hope to this dying world.
You may have the best actors, the best cinematography, the best whatever, without a good script and a Christian message your movie will not be any good.
A good example of a good script but no good message is the movie, "The Adjustment Bureau" The overall plot is a excellent plot. Its well built and is thrilling and exciting. But the theological message is warped. The message is that God is many people and that we can control our fate. As a Christian this ruins the movie. Our scripts must be good thematically and sound theologically as well.
So as Christian film makers and servants of God our films MUST glorify him.
