About 1h:18min into the movie, when Johnny is facing the Chinese leader, the Chinese dude gets shot several times in the chest. You can see the exit wounds on the front of his chest, but the bullets should have continued and hit Johnny or the water tank behind him. Apparently the bullets vanish into thin air after they go through the guy's body. If you look at the angles between the shooter, the now-dead dude, Johnny, and the water tank, it must have hit something.
