I'm not one to tout the "people's media" that blog fanatics go on about, but here's an interesting idea: Podcast DVD commentaries by fans, timed to match the film. The writer and director of "The O.C." did something like this for one of their first-season episodes, which unfortunately didn't make it onto the DVD. I think it's a great idea, although I don't know what the studio's legal departments will say. We've seen a lot of uber-fan and critic commentaries on discs, but this goes even farther. While it has the potential to be abused, especially by fans who obsess over certain series or movies, it also has a chance to give alternate perpsectives from the audience, or second chances for those involved with the film.
