Amazon Studios > scripts for your use
I just noticed this:
Making Test Movies at Amazon Studios
Test movies are inexpensive, full-length movies that tell the whole story of the script in a compelling way. They should have good acting and sound, but polished visuals are not required. Even primitive visuals will help people imagine what a script would be like as a finished film. A table read, with people saying lines and describing action, qualifies as a test movie.
