I don't want to spoil the movie for those who haven't seen it by giving too many details. All I can say is this is the most violent role I've seen Masaya played, even more violent than Shirase in Brother.
I knew that Masaya spoke English and Japanese in this movie. I was surprised when he started to speak Cantonese. I don't understand Cantonese so I couldn't tell whether he did a good job or not.
