Continuity mistake: In the beginning when the old man opens the book you can see there is nothing on the desk. When Snakehead close the book a knife suddenly appears on the desk. (00:01:40)
Continuity mistake: In the beginning when Snakehead has received the book from the old man he says "The only pitiful is your life". He grabs a knife and we see him stretching his arm out against the old man. When it cuts Snakehead has his arm bent with the knife under the old mans chin. The way Snakehead stretched his arm he would have stabbed the old man right in the face, not placing the knife under his chin. (00:02:35)
Continuity mistake: When Snakehead moves the knife away from the old mans chin we see in the wide shot that the old man puts his hand to his mouth. When it cuts to a close-up he does it again. (00:02:50)
Continuity mistake: When Jackie is waiting for his octopus meal he is holding his hand on the counter. On the counter edge we can see a piece of cloth. When it cuts the cloth is gone, and a sort of cookie has appeared as well. (00:03:25)
Continuity mistake: When Jackie throws away the octopus he is about to eat he runs over the road and a white car is coming against him. We can see that Jackie is going to be hit by the car, but the scene is cut to a frontal shot of him running. But this time he is running a bit different and isn't hit at all. (During the ending credits they show Jackie getting hit by the car from a different angle). (00:05:15)
Continuity mistake: When Jackie is sitting in the truck and he spots the light coming up from the sewage he gets out of the car while placing his right hand on the truck. When it cuts his arms are down. (00:09:25)
Continuity mistake: When Jackie removes the lid from the sewage opening the angle he is standing while looking down changes when it cuts from inside the opening. His grip on the lid also changes between the shots. (00:10:00)
Continuity mistake: The rock Jackie picks up in the sewer is smaller than the one he throws in the next scene. (00:10:35)
Continuity mistake: Around the beginning of the film Jackie is fighting some guys in some underground tunnel and you can see his shadow on the wall behind him. It is in the wrong direction considering where the light is coming from. (00:11:00)
Continuity mistake: When Jackie is fighting the two guys in the sewer he kicks one of them and splashes some water on the wall beside them. Later we can see the wall is completely dry. (00:11:30)
Continuity mistake: When Giscard grabs Snakehead and says "Cops. We gotta go," we see him grabbing Snakehead's left arm. When it cuts he is holding around Snakehead's waist. (00:12:00)
Continuity mistake: After Snakehead kicks the candleholder, the way the curtains begin to burn change in the next scene. (00:12:10)
Continuity mistake: When Jackie gets to Jai, they are surrounded by burning curtains. Jackie covers Jai in Jai's cloth and jumps through the fire. If you look closely you can actually see the cloth catch fire as Jackie jumps through the fire. When it cuts to a close-up of Jackie the cloth isn't burning anymore. (00:12:35)
Continuity mistake: After Snakehead gets away from Jackie the first time he is sitting in his car. When he says "Interpol is all over me. Can't stay here any longer", he has his hands down. In the following scene his hand is by his chin. (00:13:40)
Continuity mistake: When we first see Jackie looking at the "Sea Horizon" through the binoculars he is wearing camouflage. Later when they are boarding the "Sea Horizon" the camouflage is gone. (00:14:25 - 00:15:15)
Continuity mistake: When one of the bad guys spots Jackie and his men lying on the container he pulls up his gun holding it with both hands. When it cuts from the bad guys point of view we see him holding it with one hand only. When it cuts again he is holding it with both hands. (00:16:50)
Continuity mistake: On the "Sea Horizon" when Jackie says "I'll cover you" to his companion, you see his companion jumping over board while holding onto his machine gun. When it cuts to him just going over board his machine gun is hanging down. (00:17:25)
Continuity mistake: In the scene where Jackie and a bad guy are pointing their guns at each other, Jackie turns his gun against the guy's gun. The distance of their guns and Jackie's gun's angle change between the shots. (00:18:20)
Continuity mistake: When Jackie and Nicole are walking through the corridor to Hammerstock-Smythe's office they pass by a door right next to his door. However when they enter his office we can see that where the other door actually should be there is a wall instead. (00:21:20)
Continuity mistake: When Watson enters Hammerstock-Smythe's office his badge is hanging outside his jacket. When Jackie hands him the picture of Jai his badge is now under his jacket. (00:21:50)
