Revealing mistake: During the fight between Yulaw and Gabe, while on the catwalk up high, they both jump into the air. Yulaw kicks Gabe, who falls to the ground quickly. The shot showing Gabe hit, was poorly done, showing him fall much too slowly, and having a soft impact with almost no bounce at all. (01:07:55)
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: 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: 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)
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: 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)
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)
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)
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)
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.
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: In the king of the hill scene, there is a point when the evil Jet Li pulls down two guys. You can see bits of the green screen in those few frames.
Continuity mistake: When the bad Jet Li is running from the cops, you can see 3 cop cars, but when he jumps from one bridge to another, you only see 2.
Factual error: Yulaw can't possibly dodge bullets while he's in a vent system for a number of reasons. For one, unless he has X-ray vision, he can't see the exact spots where the bullets are coming at him as he would hear the guns going off simultaneously, thus couldn't know where to move to be safe. The second issue is he doesn't have room to maneuver around like he can on the ground. His superspeed is irrelevant in this case with him being both blind and encaged.
Plot hole: There is no way Yulaw could have successfully killed off every single other version of himself but Gabe. Death is a very unpredictable thing, and it's not possible for Yulaw to have known the exact date and time to be in every universe to kill each variant of himself before their deaths in that universe. Or, are we to believe accidents and other forms of death beyond natural are not possible in any universe but the Anubis universe?
Continuity mistake: At the beginning of the movie where Lawless is following the cops, he kicks the bars, two are bent a little, in the next shot, you see three bars that are bent a lot.
