I love audio commentaries and try to listen to all of them, but am often frustrated by them. It seems that many participants doing commentaries are either new to it, or don't really understand what an audience expects or appreciates in a commentary. So I submit to them (and you).... The Audio Commentary Bible 1) The commentary should be (mostly) scene-specific. 2) The commentary should continue throughout the film/ television episode and SHOULD NOT be intermittant (I am looking at you Scorsese box set). 3 )For multiple participants in a commentary, they should all be together in the same room viewing the film, or not at all. If some are together, the person or persons not with them should not be recorded and edited in later as this grinds the flow of the commentary to a halt. 4) Tangents are fine and should be encouraged, but if a major story point is flowed over, the commentator should back-track to cover it. 5) Participants in a commentary should take the time to review the film BEFORE commenting on it so they can gather their thoughts and provide some meaningful insights. 6) When the commentators refer to specific dialogue, that dialogue should be audible to the audience. The listener should not have to rewind, turn the commentary off, listen, then rejoin the commentary. 7) All DVDs should have the option of switching to the commentary, and back, on the fly, without having to negotiate through the DVD menu screens (this goes for subtitling on the film as well- some of us like to view the commentary with the subtitles on so that we don't miss the dialogue). 8) Try to keep the self-congratulatory butt-kissing to a minimum. And if you made a total stink-bomb of a movie, don't insult us by trying to cover it up with your self-deluded sense of brilliance, but rather try to examine what went wrong as this makes for a far more interesting commentary. Anything else you would like to add to this?
