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)
Suggested correction: It's possible Benedict's thugs couldn't hear Danny and Bruiser's conversation earlier since they were just speaking normally, but they can hear Bruiser playing up the "beating" by being deliberately loud and crashing into the furniture.
I do not believe that is correct because Ocean yelled after Bruiser hit him.
Plot hole: We see the team steal roughly $163,000,000 dollars via a phony SWAT team. Six disguised SWAT members go down and eight SWAT members (now including Yen and Linus) come up with the money hidden in duffel bags and load it into their fake SWAT truck and drive off. The problem? $163 million in hundred dollar bills weighs nearly 3600 pounds. That would require each man to carry 450 pounds of bills up the elevator and across the casino floor at an brisk pace. Just lifting that much weight off the ground would be impossible for all but an advanced power lifter, but we see the eight (which includes a 100 pound gymnast and a geriatric) pick it up and walk out with ease.
