I am looking for some Takeshi Kitano films, including Dolls and Zatoichi, and is seems that some places (such as Yes Asia) offer both the Korean and the Japanese versions. As the latter appears to be twice as expensive, is there any discernible difference between the two? From the description it seems that they are the same, save the Korean version comes with extra Korean subtitles. Is there anything to be aware of? Is it worth paying higher price for the Japanese version?
