The official Blu-ray has seven mini-featurettes. Seems kind of bare bones for such a major summer release, eh? Indeed it does, because Paramount has divvied up all the other features — including the commentary tracks with the cast and director J.J. Abrams, and several additional featurettes — have been given exclusive to the Target release, the Best Buy release, and the iTunes download. Meaning 1) if you buy the normal version you’re getting less than half the special features created for the home video release, and 2) if you want all of them you’re going to need to purchase at least three separate versions.
I’m sure that this sort of thing has nothing to do with people pirating movies. Heavens no.
