1. Don't bother to agree to do a commentary unless you're someone interesting, not just the only guy who speaks good enough English to get away with it.

2. Talk about the movie. Talk about what is happening onscreen. Do not wibble on about how you were 3rd from the left white guy in this particular HK movie and how you once got to be in the background for the fight scene in that other movie altogether where Jet Li broke his nose. This is not why you're there, honest.

3. The audience did not buy the movie to listen to you droning on about things that nobody else is interested in.

That is all.
