Plot hole: Where do the flyers come from that are in the bags that are carried out of the vault and into the van? Danny and Linus couldn't have taken them down there and there is no room with the Chinese man. They are carried out to the van before the SWAT team appears, which means they'd have to have been in the vault to start with? In the commentary by Steven Soderbergh he acknowledges that there's no explanation. (01:35:05)
Plot hole: When Bruiser (the man who's supposed to beat up Danny) is faking the noises of punching Danny, the two thugs can hear him through the door. But earlier, he punched Danny by accident, then started to talk to him. The thugs should have been able to hear their talking through the door as well. (01:15:30)
Visible crew/equipment: When the Malloy twins are introduced and seen racing each other with the monster trucks, the camera crew is seen several times in the reflection of the trucks. First when the camera pans out to see the large truck and then at the top of the door when the close up of Turk Malloy in the big truck is shown. (00:18:30)
Visible crew/equipment: In the scene where the Chinese acrobat is climbing out of the movable money safes in the casino vault, when he is actually climbing out you can see someone behind the movable safe helping the acrobat out. And then the camera angle changes, then at the left side, behind the safes, you can see the persons foot or back. It's black in colour.
Continuity mistake: Note the bad cut as the Chinese man is first knelt down looking at the briefcase on top of the mobile safe then a camera angle change shows him stood and looking behind him before positioning himself to jump. Then note how his body angle changes when falling off the top of the cabinet between cuts. Look carefully to the right of the screen and you can see a Perspex sheet wobbling. (01:23:05)Paul Andrews
Visible crew/equipment: After Rusty makes the proposal to Benedict and Tess finds him on the casino floor, the next shot shows Benedict thinking. When the camera pans across you can see the reflection of the crew in the glass wall behind Benedict. You can see this over his right shoulder for a few seconds. The crew is also seen in the next shot panning back across the room in the same exact place. (01:32:40)
Visible crew/equipment: When the men are standing around the EMP generator, the camera crew is reflected in the glass of the device.
Continuity mistake: In the scene in the middle of the film where Livingston is telling Danny that he has been red-flagged, Reuben is sitting on a couch smoking. In one shot we see him from the front taking a puff with his cigarette in his right hand, then in the following shot from behind Reuben the cigarette is now in his left hand. (00:59:35)The-Immortal
Continuity mistake: When Tess is first coming down the stairs, if you look closely you can see she is not wearing any shoes. But when it cuts to her coming down the last few steps she has on some high heels. Which would have very noticeable while she was walking down the previous steps. (00:44:30)
