This is a great chat track. Michael Mann doesnt really discuss each scene as we see it, he delves into the background information. Telling us about the things the cops say and why, the things they do and why and gives out tons of information on the real life drug world proving that either he has seen way too many cop shows or that he really put in a heck of a lot of research for this film.
This is one of the best commentaries of 2006 so far. And makes the viewing of the film so much better.
My ONLY complaint is that he didnt point out all the new sequences in this unrated cut or the sequences that he removed (he does say he put scenes in and took scenes out but thats it)

Mann, ever the devil for details, never really gives a play by play of what were watching, instead talking in great detail about the research and development of the story. He’s an informative, chatty guy that you can listen to for hours.

Without sounding redundant, I'll just say this. If you're looking to make a crime film, your best bet is to listen to Mann's commentaries, I mean in general. He knows his research. It's a very enriching commentary and so far all of his that I've listened to, are. What I did realize about his commentaries is that if you're looking to learn about filmmaking process or analysis from Mann as far as shooting techniques go or theory on the process, you won't really get much. But as far as giving you insight into the world this film is molded after, you're in for A LOT of great stuff.

Like all of Manns commentaries, this one really adds to the enjoyment and understanding of the film, and teaches you about film making. He does spend some time praising the actors, and his primary technical people, but most of the time he is describing the reasons why the film was done in the way it was. There are backstories, problems that were solved, lucky things that happened. But mostly a lot of details about what these characters are doing. To be honest, it is sort of a good instruction manual on how to be a drug deal, and undercover cop, and various types of security/bodyguard type roles.
