On stabs the "Big Boss"  with his own fingers is much more explicit. Instead of the two staring at  each other with mean glares, the camera is shown at the bottom of the boss  torso showing blood running down from beneath his shirt and down on his  pants. The camera then pans up showing the knife that Cheng kicked at the  boss sticking out of the boss chest. We then see Chengs fingers puncturing  the ribcage of the boss. Finally, the camera shows the two giving the mean  glares. This scene was cut from the American version because it would have  been released with an X rating. Also, when this scene was cut, it confused  people about what did Cheng do after he kicked the knife and ran towards the  Boss. The only thing that gave a clue was the puncturing sound effect when  Cheng stopped.
