Almost every release of every film ever made (on film) is cropped somewhat. Hell, when you see it in a theater, it's cropped a bit on all 4 sides, and if you see an open-matte 1.85:1 film in a theater, you're entirely at the mercy of the projectionist when it comes cropping the top and bottom properly (for an example of what happens when this is done improperly, see the original pressings of Back to the Future Part II and Part III on DVD).

It's not that the Blu-Ray is cropped while the D-Theater version isn't. It's that the framing is done slightly differently. It's cropped a bit more on the sides, but a bit less on the top and bottom. I don't see a problem here (unlike, say, the GoldenEye Ultimate Edition DVD - now there's some atrocious cropping).

And fuck, I'll say it - I like the Blu-Ray's color timing more than the D-Theater's. The D-Theater has way too much of a red shift.
