Joseph Said:

I am looking for a good, inexpensive online screenwriting course.?

We Answered:

I have never found one worth it. The best way is to read scripts, understand the formatting and write scripts with new ideas. Or old ideas that have been done a million times but told differently ex. Romeo and Juliet... on a ship, Titanic! There are some books that can be read but be prepared to be told different things from different people. There is not a real way to do it so if your script is different it will be torn apart by that person.
and knowing someone in the industry helps get it made no matter what it's like...
