Continuity mistake: During the fight with Gabe and Yulaw, Yulaw does a powerful move of lunging forward and smashing Gabe with both his fists, sending him flying into a green metal box that crumbles from the impact. Gabe then falls to the floor, close to the box. The shot changes to Yulaw thinking he has victory, then back to Gabe. Gabe is now noticeably further from the green box, and his arms and legs are in different positions. (01:08:40)
Continuity mistake: Both Gabe and Yulaw have their hair parted on the right side. But during the fight between them, you can tell they flipped the image of the film as it shows Yulaw's part on the left side in one shot, and again a couple shots later. It then returns to his right side. (01:11:35)
Continuity mistake: At one point in their fight, Gabe hits Yulaw hard enough he flies back into a machine, and causes a shower of sparks to start falling down like rain. One shot shows Gabe step into the shower of sparks, and shows many of the sparks bouncing off his head and shoulders. The shot cuts to Yulaw, then back to Gabe. Gabe is still in the shower of sparks, but not one is touching him. In fact, through the entire time those two are in the sparks, it never again shows any hitting or bouncing off them, except towards the end of the spark shower when Yulaw is flipping through them. (01:10:30)
Other mistake: In the penal scene with the pyramid, Yulaw knocks a person off the pyramid, and he rolls down the steps. A short way down, he stops rolling, and you can see him push himself off another step to get himself rolling again. (01:16:40)
Factual error: Just after TK gets the gun for Yulaw, who is pretending to be Gabe, she sees the real Gabe out the window. It cuts to him crouching behind a fence, with his dog in front of him. The dog has its back to the camera, and is facing Gabe while sitting down. Here, they dubbed over a sound of a dog growling to make it more suspenseful. But that part is entirely wrong. One, it is Gabe's own dog, who in a previous scene was happy to see Gabe and wagging his tail. He would not be growling at his master in such a manner at this point. The dog is also sitting down in a relaxed posture. If the dog was actually growling at him in such a threatening manor, it would not be sitting down, but standing and head lowered. (00:56:00)
Revealing mistake: When Yulaw and Gabe are having a confrontation next to the MRI machine, Gabe jumps across the table and kicks Yulaw. Here you can see the attempt at face replacement on the stunt double as Gabe, which looks fake and plasticy. (00:34:50)
Continuity mistake: When Funsch does Gabe a favor and sends him to a new universe rather than his old one, Gabe goes through the wormhole and winds up in the middle of the street. Shown previously, traveling between the universes is extremely painful, and renders the traveler very disoriented for a time. Just before being sent to his new home, Gabe was already sent through a wormhole not but a few minutes before, and was barely able to stand, it being his first time dimension hopping. Yet when in this new universe, he stands up and rescues a dog, showing no sign of disorientation at all, despite not only just being ripped apart and put back together, but it happening twice within just a few minutes. (01:17:50)
Continuity mistake: When Yulaw slams Gabe into a metal box, the glass and debris falls next to his feet. You see both glass and a few chunks of metal, with one especially large chunk of metal. It cuts to Yulaw, then back to Gabe, and now the metal chunks are missing and it just shows glass shards. (01:08:40)
Continuity mistake: When the police trucks are racing out of the garage and the first one hits its roof on the opening garage door, look at the truck the very next shot. There is no damage. (00:06:20)
Continuity mistake: When the evil Jet Li hits the motorcycle cop with his motorcycle, he crashes into a store gate and bends it. The camera angle changes to a wide shot and the top of the gate is now broken when it wasn't in the previous shot. (00:48:35)
Other mistake: Several times throughout the movie, it is said that Yulaw killed himself 123 times. And at his sentencing, he was convicted of murdering himself 123 times. However both Funsch and Roedecker say the first time he killed himself, he was forced to defend himself against another form of himself, which wouldn't be murder, because he was defending himself as an MVA agent.
Suggested correction: More likely, when they mention he's killed himself 123 times, they're referring to the number of times he's intentionally killed himself.
Audio problem: When the MVA agents confront Yulaw in the hospital, Funsch locks in on Yulaw's right shoulder first. His gun's sights show up, being blue, and then turn red. There is a sound that the gun makes before the sight vanishes. The shots change, and you hear the sound end while the site is off screen showing the scared doctor. Then, several seconds later, it shows Roedecker's gun lock in on Yulaw's left shoulder, and the sound happens as the blue site turns red, and vanishes. However, the site from Funsch's gun is still on Yulaw visible and red, only now vanishing. The sound it made already indicating that it was gone, but it wasn't. (00:33:25)
Other mistake: In the chase scene after Yulaw first tries to kill Gabe, Gabe is chasing Yulaw on foot and shooting at him. There is a parked police car that Yulaw runs in front of and by. Gabe fires a shot from his pistol, and the back glass of the police car shatters. However, Gabe was in front to the right of the car. The front windshield was undamaged, and neither of the two side windows were damaged. So Gabe was in front of the car, shot, and somehow only busted the back glass. (00:23:30)
Factual error: When Gabe is shooting at Yulaw through vents he first shoots at the opening above the door, then at the spot where Yulaw's hand shoots out. After this, he fires at the vent above the door again, only there are less bullet holes than there should be after the first shots at that area, let alone the two sets of shooting together. Also the hole where Yulaw's hand came down is no longer there. (00:20:30)
Continuity mistake: When Jet Li has been sent to the penal planet and is on the floor, some guys walk up to him. Jet Li walks up the steps and the guys call him fresh fish, but they're still looking down to the floor. (01:15:50)
Continuity mistake: When Yulaw is in the vents and the police are shooting at him, you can see that the policemen's flashlights on their guns are on and pointed at the vents, but in the next shot where it shows the vents, there is no light shining on them. (00:04:55)
Continuity mistake: Right before the evil Jet Li shoots the cop Jet Li, the cop Jet Li slides down a concrete wall with a huge groove in it. In the next close-up, he turns around and he is standing farther down in front of the wall. (00:23:05)
Other mistake: When the bad Jet Li is fighting his way to to the top of the pyramid, he throws one guy down the stairs. If you look you can see some people waiting to catch him.
Other mistake: At the end of the movie on top of the pyramid, a guy comes from the right side. Jet hits him in the stomach, and then in the face. But you can see that Jet Li doesn't even come close to his face. (01:16:45)
