Factual error: The scene where Nightfox steals the Faberge Egg is all wrong. A laser security system must have a photoelectric receptor at the other side to detect if somebody pass between the two devices. As shown in the film, the laser beams points everywhere, so the system can't work and somebody could cross a beam without starting the alarm. Even if it was some weird system based on measuring distance it wouldn't work - if the laser hits the floor at an angle it won't bounce back to the source, it will reflect towards the ceiling.Dr Wilson
Plot hole: How did Benedict have time to visit all of Ocean's 11 without them informing each other? (That is, only Danny should have been surprised to see Benedict.) He had to travel to Connecticut, Utah, Miami, London, New Jersey, Chicago, New York, Louisiana, Las Vegas, and Los Angeles. As soon as Danny knew, he was on the phone (presumably calling the others).
Deliberate mistake: Laser beams are normally not visible, except for a small dot where they hit a surface. Even if made visible, using smoke or dust or special glasses, they are thin as threads. Obviously something more visual was needed for Toulour's dance act, hence the thick beams of light.
Continuity mistake: Before some of the group is arrested, Brad Pitt is sitting at a restaurant table and 4 cops approach him (2 from the front and 2 from behind). In one shot, the two cops in the front are seen about to sit down, but in the next shot, they are just arriving and aren't even close to the chair. (01:18:50)
Visible crew/equipment: In the scene of Matsui's interrogation, you see Catherine Zeta-Jones leave the "pre-interrogation room", walk behind a glass through a corridor and finally enter the interrogation room; in the last seconds of her walk, you can see the shadow of the moving camera on the two-way mirror.
Other mistake: Catherine Zeta Jones requests that she be allotted extra man power and requests that a commanding officer sign a "Form 1077". The body of the form is in Italian, but the title of the form is in English and under the signature line, the words "signed and agreed" are in English. Obviously, this was done so that the point would be made that the officer did not sign and agree to her request.Allyson
