In comparison to the Region 1 release, the Region 4 release misses out on:
The Region 1 release also has a Spanish soundtrack (way too logical for a Latina film). If you need to see the film, then frankly the Region 1 release is far ahead of the Region 4 and probably comes a cheaper price.
There is a Region 2 release in Norway but since I cannot understand Norwegian and any of the online translators are so poor as to make the review I found even more unintelligible, unfortunately I cannot tell you much about it. Most likely it is similar to the Region 4 release however.
