I want to introduce you guy to a piece of software that I have started using. It's name is Celtx. It is an integrated pre-production software for film, theater, audio, Av and comics.
You can use Celtx for the entire production process - write scripts, storyboard scenes and sequences, sketch setups, develop characters, breakdown & tag elements, schedule productions, and prepare and circulate informative reports for cast and crew.
It has a choice of fully integrated production tools so that your end product turns out the way you want it.
