I haven't checked out Ubuntu Studio yet, but I didn't see this program listed in the documentation. It's a program called Celtx:

I highly recomme
5a8
nd it for anyone doing any kind of film production work. It'd be an awesome program to be included in the next version of Ubuntu Studio too! It's not just a screen writing tool, it organizes your whole film, radio drama, theatre or other production. It has:
-A production schedule
-Media management for all movies and clips
-Contact info and cast and crew
-Web services including launching your project for the public or privately to only those whom you allow (i.e. cast and crew)
and soo much more. I've been in film production since 2004 or so and I live by this program.
Take a look! Maybe you will too!
