The Region 1 version of this disc was released in the first half of 2003. It has fewer languages on it, and no layer change (not that you can see the one on this disc).
As far as I can ascertain, the R1 transfer may be better than the one on this R4 disc, or not. There are a number of reviews, and they vary.
I suspect that you would get pretty much the same thing with either version — a film that doesn't really satisfy. Maybe the best option is not to buy it at all?
