Both the R1 Special Edition and the R4 Special Edition have butchered opening sequences (a slow-paced montage with Japanese credits is minimized to freeze frames with English credits overlaid). The original R4 and R1 releases, the R2 (UK-Optimum) release, as well as the 2-disc R2(JP) and recent Lupin the Box R2 (JP) are all uncut. As an aside, the R1 Special Edition has production art as an extra, but there are fewer images and they have a much smaller viewable area. (Thanks to lupinthethird.net for this info).
