DVD??

Nothing about the main characters at all (there's no deleted scenes, bonus scenes, etc.). It's just items related to making the film (running low on money, conflicts with interns, he bought some Avid stuff and had a bunch of stuff stolen, etc).

There are a few 'deleted scenes'. Just stuff that didn't get put into the final project for whatever reason. Considering the whole movie is about the real lives of real actors who aren't acting, it's hard to say that more could be added to the documentary by having any actor commentary on it. As much as the project allowed, you can see a good bit of the 'inner lives' of these actors and the director just by watching the film.

There's also a bit of what I'd consider a 'video log' of the director filming himself and commenting on various things related to the making of the movie. Quite open in that, actually.

There is also a commentary track by the director and another person who was involved in it from the beginning, as I recall. It's a fairly revealing commentary, as the director gives some context and describes occasionally how he intended to elicit certain reactions.
