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.
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.
Danny Ocean: Do I look 50 to you?
Basher Tarr: Yeah.
Danny Ocean: Really?
Basher Tarr: Well, I mean, you know, only from the neck up.
Trivia: When Topher Grace tells Rusty, "I totally phoned in that Dennis Quaid movie." he is referring to an actual film he starred in, called "In Good Company". (00:15:35)
Question: What is the 'lost in translation' scene with Robbie Coltrane about? (is it actually a reference to the Bill Murray film?).
Answer: A "lost in translation" is a kind of con - Danny, Rusty and Matsui basically pulled a prank on Linus to make him feel like he didn't know what they were talking about when, in fact, they were just speaking gibberish.
Almost right. Actually, Danny, Rusty and Matsui weren't just speaking nonsense, all the conversation contains their plan.
Answer: It's a joke that Matsui plays on newbies. Near the end of the film, When Linus tells his mother (Cherry Jones) he blew the meet with Matsui, she explains that's his idea of a joke on new players. Linus then comments he didn't see that coming. (Damon shows a moment of bad acting, he can barely contain his laughter).
Suggested correction: Talour would need to see the beams in order to get through. I would attest that he let off a low grade smoke canister with a fine mist like a concert hazer to make the beams visible yet not trip a smoke fire detector.
