I'd just like to point out that this release has scenes missing. For the theatrical cut you'll need to get the American release. Don't get the Lions Gate DVD because it's not widescreen. Instead search for the out of print HBO release or the Blu-Ray, which is region free.
As for the quality of the Blu-Ray. According to reviews I've read it's not a good one, with heavy DNR and other issues, but colours and contrast are supposedly superior to the DVD.
