I added the video podcast Adventures in Filmmaking to my iTunes list today. I normally try an episode of a podcast and then if I like I subscribe. I added the first one and was very impressed.
These guys were part of the 48 hour film project and their first podcast shows their short film Replacing George. The film feels great and looks good. The most impressive thing was that it was done in 48 hours with random stuff added. I hope they talk more about how they did it. For now just go check it out.
