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: In the garage when two cops are looking for Gabe, they are startled by a cat. Just before the cat jumps out, both cops have their flashlights on. Once the cat jumps out and they follow its movement, the camera cuts to show them turn around, and now the cop with the green jacket's flashlight is off. (00:52:45)
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 Jet Li arrives home after checking himself out of hospital, on his way up the stairs there's no light visible through the curtains. Just after he reaches the top, we can see them again behind Carla Gugino, and there's daylight pouring through them. (00:24:25)
Continuity mistake: Right after the prison escape, Jet Li goes after another version of himself that is a cop. The evil Jet is hiding in the duct work, and even though the majority of cops are firing their weapons straight ahead, the bullets are hitting the duct work 10 feet above them. (00:20:30)
Continuity mistake: When MVA Agent Harry Roedecker is hitting the evil Jet Li with the fire extinguisher you can tell that the entire scene was pasted together because Jet Li's hands are up in one shot then down in the next, then back up again as he's being hit. (00:44:15)
Factual error: When Gabe is confronted by his fellow officers after they think he went crazy, he gets into a short fight with them. He subdues them handcuffing them together and to a wheelchair. The chains on the handcuffs are much too long as to what they should be. This was done to allow the stunt to be done correctly. (00:37:40)
Audio problem: When TK finds Yulaw in the attic, Yulaw is impersonating Gabe and asks TK to get him a gun. Just before she walks away, the last thing Yulaw says is "TK." But his lip movements don't match up to what he says. (00:55:10)
Plot hole: In the second foot chase scene, with Gabe chasing Yulaw, both of them make it over a tall wall with razor wire on the top. Yulaw does it with little effort, and Gabe struggles doing so, but also makes it. They only got over the wall because of their enhanced abilities from the murder of their other dimensional selves. Later in the movie, Gabe says. "I wouldn't be here, if you guys didn't make it up right behind me." His friend then says, "We never made it up that wall." Ordinary humans could not do what the two Gabriels did. However, in that chase scene after Yulaw shoots Gabe and he falls over, it shows the MVA agents suddenly popping up over the wall and shooting at Yulaw. How did they manage to get up the wall? (00:24:15)
Continuity mistake: After Yulaw killed Lawless, he makes a run for it through a busy street and past a section of road construction. There is a cop chasing him and looks down saying, "Holy shit... he's doing 50." Only two shots later it shows Yulaw running across an intersection, and he is not moving anywhere near fast enough to be going 50mph. (00:06:55)
Revealing mistake: While still fighting on the cat walk, Yulaw does a spin kick at Gabe's face. You see Gabe react as if he got kicked in the face, and tumbles over the side. You can see the kick never even contacts Gabe's face as the stunt double reacts to it. (01:07:45)
Continuity mistake: When TK sees the dust on the floor below the attic hatch, she takes off a white jacket and drops it on the floor right next to it. She then goes to get a chair and returns. Now the jacket is gone. (00:54:10)
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: In the chase scene after Yulaw kills Lawless, it shows him leaping across a gap between two bridges. In second shot, when he first start the jump, it shows him make it half way across the gap. Then the next shot shows him barely past the first railing, not close to half way yet. (00:07:10)
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.
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.
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?
Chosen answer: After he says he will go to the hospital, his wife says "ni shuo de" which simply means "you said so" (so now he has to do it).
