One odd thing about the bluray (& I assume the DVD too) is the aspect ratio. The film was released in theaters in a scope 2.40:1 ratio, while the bluray is 1.78:1 (or 16x9). The odd thing is, it's not cropped at the sides but opened up at the top & bottom so you're actually getting more image than less. Apparently the film was shot in 1.78:1 & then cropped vertically to a scope ratio for theatrical release. This is similar to what used to go on with films shot on "Super35" where the 4:3 "pan & scan*" home video versions actually had more picture than the widescreen theatrical versions. page talks about it & has a comparison shot (note that the color of the actual bluray is not faded like the screencap, it looked quite nice)
*they weren't actually pan & scanned, the frame was opened up from the widescreen matting, revealing the full image that was exposed, which was actuall 4:3.
Here's an example of super 35 from T2
