In the original cut of the film, in the scene after the car chase where he forces him to go and kill Gou Fei, Judge also tells Sam to bring him Gou Fei's eyes as proof of his death. Sam can't kill Gou Fei, so he cuts the eyes out of one of the bodies of the family in the house. Judge takes the eyes and eats them. This was also a payoff of the scene from earlier in the movie where Judge compliments Gou Fei's "pretty eyes" when they first meet. If you watch Sam in the normal versions of the film, as he comes out of the house you can see his right hand is clenched and holding something - the eyes, of course.
This film did poorly at the Hong Kong box office, where fans were not interested in seeing Chow Yun-Fat play a violent criminal. It was however a critical and cult favorite in the US and UK.
The first song in the trailer is Get the Funk Out by the US band Extreme.
