The process and end result of writing screenplays and manuscripts can vary greatly, writer and producer Craig Miller explains. Authors writing a novel will need to evoke imagery and concepts through the written word, while screenwriters don’t need to describe everything in such detail, because the audience will be able to see it for themselves. That’s why Miller refers to screenplays as blueprints. They are not designed to be read by an audience member. Instead, screenplays serve as a guide for directors, producers, actors, and other industry professionals to help bring a vision to life.
