Interestingly, I've never seen this mentioned on a film site, only on a tech site. It is a fascinating tool for pre-production, incorporating scriptwriting, story development, production scheduling, production reporting and more in a single application. It's still young and it's not going to challenge high-end script writing software for awhile, but it's free, easy to use and shows promise. I've decided to use it on my latest project to see if it's robust enough for me and I invite you to give it a try as well and post your comments.
Available in Mac OS X, Windows XP and Linux versions.
