I have only been able to make it through part of this commentary, and it's a shame. For as good as this movie is, Christopher Nolan is a rather dull commentator. The track focuses on the technical side of things.

However, if you have an interest in such things, it's really quite a good commentary.

Nolan's tone and pacing are monotonous. His psychological profiling of his characters - in case you missed the clues on screen - amounts to so much narration in disguise. Behind-the-scenes info is scant, largerly limited to sporadically discussing which shots were important or difficult, which scenes were filmed on location or sets, and the occasional praise for his collaborators. Mostly, though, he's clearly fascinated by the story, which is really only clever BECAUSE of the fragmented way in which it's presented.

This track, should you make it through, has a secret "branching" feature that provides one of four slightly varying commentary endings. The changeover occurs at 1:33:52 in the film (the end of Chapter 13 on the disc). If you happen to be listening to the non-commentary audio tracks at that point, the disc continues to Chapter 14 in Title 1 and the commentary, if you switch over to it manually, becomes garbled from about 1:37:20 to the end of the film.

If you're listening to Nolan's commentary track at 1:33:52, there's a brief pause and the disc switches to Title 2, 3 or 4 (seemingly at random). These titles contain three subtly different versions of the ungarbled commentary for chapters 14 through 16. Only one difference is significant - "Teddy's lying" vs "Teddy's not lying" - so repeat listens might best be left to purists with plenty of time as the feature appears to randomly choose between the alternate tracks.

Otherwise, a surprisingly dreary track to an exemplary DVD presentation of a mildly overrated film.

I disagree with those who disliked this track. Yes, Nolan is a little dull to listen to, but the information he provides is actually quite informative and interesting. This was a very complex film, and he answers quite a few questions and also points out some things I never noticed (and I have seen this film numerous times). Focus more on content than delivery and you should enjoy yourself.
