They should keep the original soundtrack for example "Requiem Dies Arae" by Giueseppi Verde was amazing for the original film. The original just wouldn't be the same without the soundtrack. Also they should have Kiriyama's hair style the same as in the novel and manga. I'm going to be murdered for this but I didn't like Kiriyama in the original. And yes Samuel L Jackson should be the Kitano or Sakamochi or Yonemi in the remake if one does accually hit the silver screen in America. Also this film should be LOOOONGGGG it should be epic like the Lord of the Rings and show off good effects and lots of characterization. I cant wait for the remake.
