Continuity mistake: When Rusty and Linus are talking to each other in the hotel room, Linus is all dressed up in a suit rehearsing his part in the scam. When Rusty says "Where are you gonna put your hands," he puts his hands together, yet in the following shot from the front, his hands are back at his side. (01:01:25)
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. (01:35:30 - 01:41:20)
Factual error: The EMP wave generated from "The Pinch" would do more than just black out the city. It would also permanently disable any electronic equipment such as cars, mobile phones, TV cameras (like the ones recording the fight), slot machines, computers, in fact any electrical equipment used in the world today, More importantly the entire security system would have been disabled which means that Benedict could not have seen his vault getting robbed from the security room. The only way an electronic device can survive an EMP is if the device is turned off.
Continuity mistake: Near the end, Linus and Danny are waiting at the elevator doors for the gas to take effect on the two guys at the vault door. Danny and Linus open the doors. Danny, in one shot, has his right arm up holding the door open, and in the following shot it is resting on the floor. (01:22:25)
Continuity mistake: When some of the group are taking the Pinch from the institute, at the end of the scene Linus is looking up at the two security guards which are almost standing next to each other. In the following shot one of the guards is just slowly walking up to the other one, even though they were almost together in the previous shot. (00:58:35)
Continuity mistake: When Rusty and Danny are trying to convince Gould to bankroll them, Gould, while eating salad, has four objects next to his right hand. The two-cylinder object changes orientation. From behind Gould, it is turned away from him. From in front of the man, it is turned towards him. (00:15:55)
Factual error: The actual Las Vegas strip has the Bellagio and Mirage on the same side of the street, separated by Caesar's Palace. MGM Grand is very far down the road towards McCarran Airport. In the film, the Bellagio is across the street from the MGM Grand and the Mirage, with Paris in between the two of them. Bellagio is across the street from Bally's, which is next to Paris. I hope this description isn't too confusing. Furthermore, a wide angle shot of the strip shows the Mirage and MGM Grand right next to each other! Obviously this was a work of computer trickery. In a shot of Basher, before he sets off the pinch, in the Bellagio parking lot, the Bellagio is across the street from Paris. However, to the left of Paris is Bally's, and the Flamingo! Shouldn't the Mirage be in the spot that Bally's occupies, if we're going by the map that Danny Ocean gives us in the scene inside the house, where he first describes the security measures in the vault at the Bellagio? So the Ocean's Eleven version of Las Vegas is not even consistent with itself!
Continuity mistake: Early on when Rusty is teaching the actors to play poker, there's a scene when Rusty says "Shane, you've got three pairs...you can't have three pairs. You can't have six cards in a five card game." Look at Topher's (the man who wanted to pay Rusty by check) cards during this scene. At first, he's holding the cards up, then flat on the table, then back up again. (00:07:00)
Factual error: In the scene when Clooney and Damon are rappelling down the shaft on steel cables, the come up short of the floor. They pull knives and swipe the cables. No knife would be able to cut a steel cable with one swipe.
Continuity mistake: Danny's hairstyle changes dramatically in some scenes in the movie. Most notably when he and Rusty are in the office building looking at the blueprints of the hotel vault. It looks like he just got a haircut. In the previous scene and next scene his hair looks longer and styled different. (00:12:15)
