Continuity mistake: When Adam Banks is playing in one of the games, he scores a goal and his teammates on the bench stand up and cheer when he scores. Problem is, Adam Banks is on the bench too.
Revealing mistake: When the kids are burying Gus, his supposedly dead face flinches when they shovel dirt on him.
Revealing mistake: When the terrorists drop the dead body out the aircraft door, look closely at the aeroplane just beneath the door, you can see the reflection of the mat the stuntman lands on, as well as the spotters around it.
Other mistake: Towards the end where they steal the chip, they are detected and about a million security guards are all running around, yet 30 seconds later, the only security guard is one man with a shotgun. What happened to their big army of security guards? (01:41:30 - 01:42:55)
Visible crew/equipment: When the guitarist almost gets hit by a bus, you see a shot from inside the bus about what happens outside. If you watch carefully you can see Robert Rodriguez in the rear view mirror holding the camera with a towel on his head. (00:27:00)
Continuity mistake: Just after the doctor started the post mortem on that little girl, the front of his gown is covered with blood. Yet, a few seconds later, after the two other guys appear, his gown looks better, with less blood. And during the whole post mortem scene, the blood spot actually changes its size a few times. (00:17:55 - 00:19:55)
Continuity mistake: When Buffy is out shopping for her dress and Pike is on his bike beside her, they stop to talk and have an argument. Buffy walks off and Pike turns his bike around to drive off, but as he does this, his bike suddenly moves a few feet away from the wall he was right next to in the previous shot. (01:01:05)
Continuity mistake: In the hockey game, the teams playing are the Los Angeles Kings and the Toronto Maple Leafs. You can notice the real logos when the camera is away from the action. When it gets closer, though (probably because of copyrights), the maple leaf is turned into a spades (from cards) with only "Toronto" written and the Kings' word and crown in the logo become just an "LA" with a slightly different shape.
Continuity mistake: In the hotel scene when Van Damme is crashing through walls to escape the other Universal Soldiers who are shooting from outside, one shot from the inside of the room shows him hitting the wall with his left shoulder, but when the camera goes into the next room to show him coming through that wall, he is breaking through with his right shoulder. (00:39:35)
Continuity mistake: Near the beginning, Jake drives a motorcycle out of the warehouse shoot-out and spins out as police cars converge on him. He has blood coming out of the right corner of his mouth, the shot changes, cuts back to him and the blood is on the left, then right again in the subsequent shot.
Continuity mistake: When crackhead drug dealer stabs Mr. Big at the table in the club, the boss pulls a table cloth, upsetting crockery. In next shot it's all perfectly tidy.
Revealing mistake: During Kenjiro's fight with Phan Xu, Kenjiro cuts Xu's face. This cut goes across Xu's headband, but the headband is still in one piece. The cut is visible above and below the band, but the band itself is untouched. As Kenjiros sword is capable of cutting a steel chain, a piece of cloth should not pose any difficulty.
Continuity mistake: Sloan's pants change from blue to white after he is captured attacking Lane's house.
