According to Ars Technica, TuneCore, a service which has made it possible for pretty much anyone to sell songs on iTunes is now doing the same for indie film makers. Apparently, all it takes is a flat, upfront fee, you get to keep all the profit from the stores which you choose to sell your film through. Albums range from $20-30, while film fees depend on the length; $550 for a 60-minute, $770 for a 90-minute feature.
This sounds like a great option. I know many people who have a difficult time getting distribution in the physical arena. This would allow their films to reach audiences around the world for a small fraction of the overall budget. I'm looking forward to finding new indie films up on iTunes.
