I've written about this a bit regarding the idea that there's distribution and then there's distribution (where you actually get paid.) It used to be that a real distribution deal was nearly impossible without many of the elements mentioned in this blog post as well as high production value. Now, nearly anyone (as I've mentioned) can get a distribution deal for nearly any kind of film, but most of those result in zero payment, so you have to be selective in embarking upon a feature length film project because the odds are very, very high that you will see no return on your investment in time and money:
