I received a copy of this version via swapadvd.com. The third disk actually consists of two special features. The first is kind of like an audio-visual counterpart to the typical directors/actors commentary. While the movie is playing in one part of the screen, other parts might show the corresponding pre-vis or story board, and instead of hearing the movie soundtrack, you hear some cast or crew member talking about the scene. The movie stops entirely in some spots so that the entire screen is used for new behind-the-scenes snippets.

I think the second special feature may be the making of Krypton, but I can't recall for certain.
