Erm... be more specific? :)

It's great to see something new on Wreckamovie, and documentaries are definitely on the rise as a film genre ("Supersize Me" etc have been mainstream hits).

However, if you want other people's help you need to do two things:

-Be very specific about the help you need

-Show that you've done a lot of work on the project yourself

At the moment you're basically just saying "write the screenplay", which people are unlikely to repond to.

What you could do is provide a summary of what the screenplay should include, refer to other works with a similar style, tell us what kind of film this will be, who it will be made for, what the budget is etc...
