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.
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!
