The Open Source Film Project looks a like a very cool idea. Here is what they do: "With the open source film project rather than having a small group of individuals put up large amounts of money to buy equipment, and resources, we will look to compile a large group of freelancers, a group of motivated and intelligent people who have one piece of the puzzle.  These people will have the passion to succeed, and the patience to work. This large group once compiled will then create the movie from start to finish, that means from finding a script, to shooting the film, to editing, and then finally to distribution and promotion.  Unlike open source software where there is not any compensation, our open source film project freelancers will be compensated, depending on the box office earnings."

You participate with a donation (I think the amount is $20) whether it be a director, editor, etc. They even have a film scheduled to go into production in May 2006. Also there is a: "limited time offer to screenwriters to give their projects the greenlight to production for only $10.00. Have your script assigned to project status and create job listings that will fill the needed positions, and get your script produced." Hope it works.
