Amazon Studios is running various competitions through the year for scripts, tests movies and other pre-production work. It might be worth looking into, though note that by submitting a work you are giving them a free 18 month option on that work.
And if you are thinking of submitting something, they've just made available a free music library of 2,000 tracks. Of course, there's a caveat to that too; you can only use them for work uploaded to the Amazon Studios site.
