The Region 4 version of this disc misses out on;
dts 5.1 Audio Track
Spanish and French Subtitles.
Trailer for Band Camp.
The Region 1 version of this disc misses out on;
Hungarian, Danish, Finish, Hebrew, Icelandic, Norwegian and Swedish subtitles.
Trailers for King Kong and The Skeleton Key.
I would favour the Region 1 version of this disc as it includes a dts 5.1 audio track.
