Revealing mistake: When Ricky's girlfriend commits suicide by jumping off the roof of a drug dealer's apartment building, the body that is shown falling to the ground is a dummy and not a human body. (01:11:28)
Other mistake: When Ricky's girlfriend lands on the ground after jumping off the roof, she is shown landing on her front, with her face and body shown hitting the ground. When Ricky is shown looking at her body at the morgue, her face has virtually no signs of injury what so ever. (01:11:29)
Continuity mistake: When Ricky punches the drug lord in the side of the head, whilst the drug lord begins to fall over after Ricky punches him, there are no visible injuries shown on his head. When the drug lord is shown on the ground in the next shot, there is a huge wound and lots of blood on the side of his head that would have been visible in the previous shot. (01:12:25)
Continuity mistake: Wong Chun stuffs a load of razors in Ricky's mouth and begins hitting him. After the warden asks Ricky a question and Wong Chun stops hitting him for a moment, we can see that Ricky's left cheek looks fine (aside from the blood running down his head). In the next shot, the razors are suddenly sticking out of his cheeks that were not there in the previous shot. (01:16:27)
Continuity mistake: When Ricky is being tortured by the warden, after the warden removes the tape covering his mouth, Ricky spits out some blood as many of the razors inside his mouth. The razors that were shown sticking out of his cheeks are not shown moving, but after it cuts to the warden with some of the razors stuck to his face, the shot cuts back to Ricky and the razors in his cheeks are no longer there. Even the ones that weren't shown being spat out. (01:16:40)
Continuity mistake: When the assistant warden and the bald inmate are walking down the corridor towards the end, two inmates from inside their cells put their hands on the bars of the cell doors to see what is happening. The inmate standing on the left has both of his hands on the bars and the inmate standing on the right has both hands on the row of bars positioned below where the inmate standing on the left has his hands. When the camera changes angles, the inmate standing on the left no longer has his hands on the bars and the inmate standing on the right now has his hands positioned on two separate rows of bars. (01:18:30)
Revealing mistake: When a couple of the inmates are watching the assistant warden drag Fa out of his cell by sticking his hook hand into his mouth, it is apparent that the man being dragged by the hook hand is a fake motionless prop dummy and not an actual person. (01:18:36)
Continuity mistake: When the assistant warden starts searching Ricky's cell, he opens the two doors to the toilet stall to see if he is in there. Whilst Ricky jumps down from the ceiling, the assistant warden has the left door on the toilet stall held open and the right door on the toilet stall closed. When he notices Ricky in the next shot, the left door on the toilet stall is now closed and the right door on the toilet stall is now wide open. (01:19:09)
Revealing mistake: When the assistant warden and the bald inmate walk into Ricky's cell after not seeing him inside, Ricky reveals himself, grabs onto the bald inmate and punches part of his head off his body, killing him. In the shot where Ricky punches the inmate in the side of the head, we can see that the actor has been replaced with a dummy. (01:19:17)
Revealing mistake: Just after Ricky has killed the bald inmate, he then goes to punch the assistant warden in his face, resulting in his one real eye falling out. In the close-up shot of the assistant warden getting punched, a fake prop dummy can be seen instead of the real assistant warden, most likely used so that it would be easier to create the practical effect of his eye falling out. (01:19:22)
Continuity mistake: When the inmates are cornering the assistant warden, he begins to walk down the stairs in a wide shot, with his left arm lowered. In the next shot, he is suddenly waving his left arm in the air. (01:20:10)
Continuity mistake: When the assistant warden falls down the stairs whilst being confronted by the inmates, in one shot his body is rotated towards the left and is face to face with some inmates nearest to the staircase. When the camera changes angles, his body is more rotated to the right and is now directly facing the staircase bannister to be face to face with more of the inmates. (01:20:16)
Revealing mistake: When one of the inmates goes to cut off the assistant warden's right arm with an axe, the moment before his arm gets chopped off, we can see that it has been replaced with a fake dummy arm. (01:20:24)
Other mistake: Just after the assistant warden's right arm has been chopped off by an inmate, part of his shirt sleeve goes missing. The part of his arm still attached to his body has a sleeve starting at his shoulder, and stopping an inch above where his arm stump ends, leaving an inch of skin exposed. And when the chopped off arm is shown, the arm is shown to have a sleeve starting at his elbow, going down to his wrist, but there are a few inches of his upper arm above his elbow left exposed. This means that a couple inches of his sleeve from where part of his upper arm was located, have gone missing without explanation. (01:20:25)
Continuity mistake: When the armoured guards appear, a guard holding a mace attempts to swing it at Ricky whilst he jumps from a staircase. In the shot of Ricky jumping down from the staircase, he is holding his shield so that it is positioned away from him, but in the next shot, the guard suddenly has his protective shield directly in front of him. (01:20:49)
Other mistake: Just after the assistant warden has been carried away by the other inmate, it cuts to the warden in the kitchen with his son and a guard. When the guard tells him the menu for tomorrow is ready, the subtitles "Sir, the prisoner's menu for tomorrow is ready." The apostrophe in "prisoner's" is shown in the wrong place. Saying "prisoner's" implies that it's just for one prisoner, and since the menu is made for all of the prisoners, the subtitles should have read "the prisoners' menu" and not "the prisoner's menu." The guard even says "They'll have some beans, vegetables and meat for lunch" afterwards, so multiple people were being referred to. (This depends on which format and which studio distribution you are watching, but it can definitely be seen on the Region B Blu-Ray distributed by MediumRare). (01:21:15)
Other mistake: Just after the warden tells the guard to limit the amount of food the inmates get in their meals, one of the inmates shown polishing the meat grinder says "You eat like a lousy king. Even your dog gets a big steak." When he says "your dog", the subtitles read "yourdog" instead of "your dog." It has been incorrectly spelt as one word, with no space shown in between the two words. (This depends on which format and which studio distribution you are watching, but it can definitely be seen on the Region B Blu-Ray distributed by MediumRare). (01:21:53)
Continuity mistake: When the warden begins forcing the inmate's hand into the meat grinder, in the first shot, we can see that his body is placed over a cloth, placed over the side. When the shot cuts, the cloth has suddenly moved much further to the right and away from the man. (01:22:03)
Revealing mistake: When the warden has finished shoving the inmate's arm into the meat grinder, there is a shot of the warden pulling the inmate away from the grinder and showing him the tray of meat made from his arm. In the shot, we can see that the inmate's face has been covered in white powder to make him appear as if his face has gone pale due to the blood loss, but it makes his face look completely unnatural, and not at all how a human face would ever appear in a situation like that. (01:22:09)
Continuity mistake: Just after the warden has chopped off the inmate's hand by forcing it into the meat grinder, the inmate falls over and some of the blood coming out of his arm splatters on the wall beside him. Two other inmates walk up to him to help him up, and now there is suddenly much more blood on the wall. The blood also changes appearance, being splattered on the wall in one shot, then being smeared on the wall in the next shot. (01:22:16)
