Just about the perfect commentary track. 3 intelligent, articulate participants in a relaxed conversation offering a wealth of information on all aspects of the production, from creation and development to casting and shooting, but without ever getting bogged down in detail and still finding time for some friendly banter.
I came to this series cold, happy to take a punt on anything penned by Sorkin, but after listening to this track (once I'd watched the whole series, although there are no spoilers so it could be listened to after viewing just this episode) felt fully up to speed with his inspirations and aspirations for the series. Exemplary.

A great commentary. Very detailed, going over everything from production history, pilot vs the series, concepts, the sets, the actors, the rehearsals, details about overlapping documents, and even the hair styles.

They do not say it, but I get the feeling this was the last of the 5 commentaries recorded (of the 10 episodes of the 1st season). And there is a lot of pointing out what changed between the pilot and the rest of the series. Not much, but they redesigned the sets to some degree as they realized there would be a lot of people talking in some of the smaller offices than just in the middle of the newsroom.

There is a lot of talk about the first scene of first episode, and how usually shows need to find their footing, but here they were perfect from the beginning. And the writer had never worked with the producer or director, or the actors with the show runners. And all are impressed that it started at such a high level and never dropped.

There is talk in depth for several minutes about writing overlapping dialog, and the problems editing and working with it. And they point out how most of these actors came from the stage, and they took advantage of this, knowing what strengths that means they had. But never stopped treating this like a tv show.

They were happy to get to shoot mostly in scene order, which is preferable, but seldom done because of the way sets are usually set up and lit. Having one giant set let them do this most of the time.

They also talk about the usual way pilots are shot, with no budget, different options, etc.. But here they treated the pilot as if the show was already approved, even building the set for it. And they did not have to do any reshoots, or recast any characters, which is normal with almost every other pilot these guys have made.

This commentary for the 3rd episode is nowhere near as detailed as the first. They talk a bit about the acting choices, but mostly compliment the other actors, talk about guest actors they got to appear, and ask questions to Sorkin about some of his choices.

Actors might be interested in the various comments about their craft, but this track is nowhere near as deep as the others.

One thing of interest is that they make a specific point to call out David Harbour, and that he is going to be a big star some day.

The two guys are clearly smitten with Ms Mortimer (and why wouldn't they be?), and this combined with her very English sensibilities and insecurities makes for a fun track.

Because Emily is here, a lot of the talk is about her, or asking questions to her. Like the last track, a lot about acting again.

One thing Sorkin says of interest is how all the characters had big moments in most episodes, and all the other actors had to be around in the background all day, basically playing extras. He also mentions that unlike most TV shows, almost every character was a lead, in that they could have had a show revolving around just them.

Too Emily focused to give it a higher rating than 6/10.

This track is dominated by Olivia Munn (man, can she talk!) meaning Jeff Daniels is pushed to the sidelines and you almost forget he's there, so it's left to Poul to try and moderate Ms Munn, as well as correcting a few misconceptions about the intent of the episode along the way.

Olivia Munn is added because a lot of this is mostly her episode. Things pick up quality wise for this commentary, explaining scene by by scene what is going on. There is talk about directions the episode almost went in before writing was done. Munn talks about the various acting tips the other actors gave her.

Of interest is when Jeff talks about how the psychiatrist was 3 steps ahead of him, and when he figured that out, he resented him for it.
Even some mentions about.

They go into long tangents about memorizing lines, not reading internet comments, and internet trolls, all during scenes I really wanted them to talk about, but still it is a great track.

A multi-participant track with the 7 contributors spread across 5 cities in 2 countries! Despite this the camaraderie between the actors is obvious throughout (with the others especially enjoying Emily Mortimer's very real discomfort at watching herself on screen) highlighting why they work so well as an ensemble cast on-screen.

This track has a large cast, all of whom seem to be enjoying talking with each other more than the show at times. A lot of talk about their favorite moments.

Near the end, Sorkin tells them what the idea is going to be for the 2nd season, which is the first time the actors hear this. And they are definitely excited.
