I allready wrote my last script with Celtx, but when I started a new one lately, I was amazed how the software improved. You can not only write your script with it, but also your storyboard, do your scheduling and reports and many more functions. Moreover, you can put the project on a server and invite different team members to collaborate.

“Celtx has all the tools you need to write, organize and collaborate in one modern, Internet friendly, free software application. It’s the most complete media pre-production software program available anywhere, at any cost.”
