The feature length commentary track by Dean Devlin and Roland Emmerich is the exact same one from the previous special edition laserdisc. Their commentary is enjoyable to listen to because they sound like they are enjoying the experience themselves, but it is not as scene specific or detailed as one might think. Hearing these professionals discuss their craft and the creative solutions they find for challenges is inspiring. When selecting the audio commentary track or language track you want to listen to you have to go directly to the languages and subtitles menu, which is made to be a three dimensional shift into Judd Hirsch's character's car where we stop at Jeff Goldblum's character's Macintosh Powerbook to make the selection. It is important to note that this is the only way to switch between language and commentary tracks.
Subtitle switching while watching the film is possible.
The chapter stop menu features fully animated scenes on the bridge of the alien mother ship. From there you have three-dimensional control around the immediate area. There are three featurettes on the second disc. It features some videotaped segments for the news segments within the film and a fantastic step by step look into the process of bringing ID4 to the big screen. My favorite part was Patrick Tatopoulos' explanations for his production design for the alien spaceships and the aliens themselves.
