Love the look of the new bacta tank. I was never fussed about the idea that it should be a different colour, but it looks very cool.
Out of interest, how much more effort would it be to render the special features as a PAL disc as well? I just find NTSC jitter extremely distracting, even when the focus isn't on the picture quality, and it would "feel wrong" having a two-disc set in different formats. If it's a lot of extra effort on your part, then don't sweat it;but if it's mainly out of concern for viewer confusion, I think having the film available in both formats and the special features only in one would be at least as confusing.
