The Region 1 version of this disc misses out on;
Although the Region 1 disc does have more extras, unless you require the language alternative they aren't very substantial. Region 1 is the winner, but only by a narrow margin, and unless you're a rabid fan of the movie, I think the local copy would more than suffice.
Note that, according to US reviews, the Region 1 version of this disc has a video transfer with digital compression artefacts throughout. Our Region 4 version only displayed these in the opening scenes of the movie, so it might suggest we have a slightly improved transfer.
