I have a question. I'm working on a story that started as a novel and will probably continue that way, but I am also thinking of making it a screenplay. There are so many visual elements that can't be seen in a novel! Anyway, do you all write your scripts from beginning to end, or is it 'okay' to write them scene-by-scene and piece them together later? I have several dialogue scenes written for the novel, since that is what I like the most in a story. I don't think it would be hard to piece the scenes together at all, but I wasn't sure how 'pros' worked. Thanks!

This is my first major fiction project. I have nonfiction blogs, written PSAs that only got produced in college and one article about Christianity published on ReligiousTolerance.org, but I've never done fiction before. My education is in electronic media, though.
