Revealing mistake: Just after the warden has shot the assistant warden with the bullet made for shooting elephants, there is a shot of the assistant warden's body inflating. In the shot, we can see that really bad prosthetics have been added to his forehead, cheeks, nose and chin to make it appear as if his head is inflating. It is extremely noticeable where the prosthetics end and where his real face begins, making the whole effect appear completely unnatural. (01:23:12)
Continuity mistake: When the assistant warden begins to inflate after getting shot by the warden, Ricky and a group of other inmates begin to back away from him and are shown standing in the background. But in the shot of the assistant warden exploding, Ricky and the other inmates have suddenly disappeared. (01:23:15)
Revealing mistake: When the assistant warden explodes after his body starts inflating due to the warden shooting him with the elephant bullets, in the close-up shot of his head exploding, we can see that his head has been replaced with a fake dummy head. (01:23:18)
Revealing mistake: When White God fires a needle through the wall of the kitchen, Ricky grabs onto it and is dragged towards the kitchen wall. Just before he crashes into the kitchen wall, a large outline can be seen in the wall, revealing where the effects team made a hole in the wall and plastered over it before filming. (01:23:38)
Other mistake: Wong Chun attempts to kick Ricky whilst flying through the air, but Ricky grabs onto his and throws his leg into the hydrogen tank. The rest of Wong Chun's body then falls to the ground, but the leg is still shown in the exact same elevated position despite the rest of his body being lowered. (01:25:32)
Other mistake: Whilst Ricky is fighting Wong Chun, White God attempts to sneak away by getting into one of the dumbwaiters, but the warden shoots him and he explodes. The bullet is shown hitting him in the face, but given the position of White God's body and where the warden was shooting, this would be impossible. When White God crawls into the dumbwaiter, the pantry door is shown closing behind him, so the bullet would have been blocked by the door and would have made it impossible to hit him in the face. (01:25:52)
Revealing mistake: When the warden shoots White God, the close-up shot of his face before he explodes reveals that the actor has been replaced with a dummy. (01:25:55)
Continuity mistake: Just after the warden has one of the guard take his son away, he and Ricky prepare to fight. At this point, Ricky has no blood shown around his mouth. But later in the scene, when the warden becomes muscular, there is suddenly some blood around his mouth that wasn't there earlier. (01:26:20 - 01:27:14)
Continuity mistake: The warden attempts to trap Ricky by pushing a table at him. On the table there is a tray filled with meat from when the warden forced an inmate's arm into a meat grinder earlier in the scene. In the shot where he first pushes the table, the meat in the tray is towards the right hand corner of the tray. Ricky then jumps over the table and the meat is now towards the left hand side. (01:26:27)
Continuity mistake: When the warden is preparing to fight Ricky, he takes his belt off and drops it on the tray of meat on the table in front of him. The warden then pushes the table towards Ricky and the belt is now positioned to be beside the meat tray. Ricky then kicks the warden across the room and the belt is now suddenly nearer to the other end of the table. (01:26:28)
Revealing mistake: When Ricky jumps over the table after the warden pushes it at him, there is a shot of Ricky kicking the warden with his foot whilst in mid-air. In this shot, we can see that Ricky's trousers are being pulled upwards, revealing that there is a wire attached to his trousers that is pulling him into the air. (01:26:30)
Continuity mistake: When the warden is kicked across the kitchen by Ricky, he lands on a sink. On the floor beneath the kitchen sink, a couple of tiles that were stuck to the wall fall off it. We are then shown a closer shot of the same area, where the tiles that just fell off the wall are now back on the wall, and two entirely different tiles have now fallen off. (01:26:31)
Continuity mistake: When the warden is kicked across the kitchen by Ricky, in the shot where he lands on a sink, there are two circular smudge marks on the wall beside him. It then cuts to a closer shot of the warden and the two smudge marks have gone. (01:26:31)
Continuity mistake: When the warden begins changing into a more muscular version of himself, in one shot, he is shown with his head pointed downwards and with his eyes closed, but in the next shot, he is suddenly standing upright, with his eyes open. (01:26:37)
Revealing mistake: When Ricky attempts to fight the muscular warden, he punches the warden in the stomach and the warden then punches him into a support column. Just before Ricky crashes into the column, a wire can be seen attached to him, pulling him backwards towards the column. (01:27:20)
Continuity mistake: In the final fight scene, there is a moment where Ricky punches straight through the warden's stomach and punches out through the other side. The shot then cuts to the warden for a second, but when the shot cuts again, Ricky's arm has suddenly been completely removed from the warden's stomach. No way could Ricky have removed his entire arm from the warden's stomach that quickly. (01:27:33)
Revealing mistake: Just after the warden throws Ricky to the ground, when he finishes saying "Your strength doesn't even come close to mine", he starts doing an evil laugh and here, we can see the actor's real tongue and teeth behind the fake prosthetic suit that he is wearing. (01:28:02)
Continuity mistake: When Ricky is sitting on the ground after being thrown to the ground by the warden, whilst the warden is telling him they've got the same kung fu style, Ricky has both his arms placed firmly on the ground. The camera changes angles and suddenly, his left arm is raised off the ground. (01:28:05)
Other mistake: Just after the warden tells Ricky they are trained in the same kung fu style, Ricky thinks to himself for a moment. The subtitles read 'If your opponent is strong, use your wits to beat him', but before the start of the line, before the word "If", a randomly placed comma can be seen at the start of the line. There is no reason for this comma to be here since there are no words shown before it. Clearly this was an unintentional error made when the subtitles were being typed out. (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). (01:28:10)
Continuity mistake: When the warden is thrown across the kitchen and into the meat grinder by Ricky, in one shot, he is shown being thrown across the room from left to right. When he lands in the meat grinder in the next shot, he is suddenly falling downwards. (01:28:37)
