I remember enjoying this movie when I first saw it years ago, and after reading the book. I have the original Region A locked blu-ray and will now have to watch this again in the next few days.
Visually it's quite a dark movie with lots of scenes in tunnels if I remember correctly. Would really like a 4K release as it would perhaps benefit from HDR, but don't suppose that's likely to happen.
This release doesn't seem to have anything extra from the original release, unless there are additional extras (other than a commentary and interview with Peter Hyams and a trailer). Also the running time seems to be the same.
