For those of you interested in writing movie scripts or comic books, I strayed across a great open source application when looking for something comparable to Final Draft (which I currently cannot afford) called Celtx. (Open source, as I'm sure you know, means it's free.)
You can download it here.
It presumably follows "industry standard" formatting for your film scripts since its inspiration was Final Draft. Celtx operates as a full pre-production suite, in which you can write your projects in different forms: comic book script, film script, novel, and storyboarding. (In the storyboarding feature you can scan and upload your sketches). It also includes a feature to keep track of your production schedule.
