- "Trent Reznor, Atticus Ross and David Fincher on the Score" (18:55) features sit-down interviews with Atticus, Trent, and later David, talking about the score, as well as in-studio interviews with Trent and Atticus as they demonstrate some of the techniques they used to create music for the score.
- "In the Hall of the Mountain King: Reznor’s First Draft" (2:30) plays the regatta scene, allowing you to swap audio between the original draft and the final version, with and without the rest of the film audio
- "Swarmatron" (4:28) again sits us down with Atticus and Trent as they demonstrate how the Swarmatron works, and how they orchestrated tracks throughout the score by multitracking the device.
These features are in HD on the bluray, and are accompanied by almost two hours of extra video about the visuals, post-production, rehearsals, just about every detail that goes into the making of the film. So if you're renting or buying, be sure to pick up the two-disc version.
