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.
Ocean's Twelve (2004)
1 deliberate mistake - chronological order
Directed by: Steven Soderbergh
Starring: Bruce Willis, Matt Damon, Brad Pitt, George Clooney, Julia Roberts, Andy Garcia, Don Cheadle, Catherine Zeta-Jones, Casey Affleck, Robbie Coltrane, Carl Reiner, Scott Caan, Bernie Mac, Elliott Gould, Shaobo Qin
Visible crew/equipment: When Ocean tells the Nightfox about the fake Faberge, there's a shot of the Nord Train. When we see the left side of the train, watch its window and you will be able to see a camera and a cameraman reflected.
Linus Caldwell: What did I say?
Danny Ocean: You called his niece a whore.
Rusty Ryan: A very cheap one.
Danny Ocean: She's seven.
Trivia: In the last scene, when everyone meets to play poker, Catherine Zeta Jones throws her hands up to celebrate a win and falls out of her chair for real.
Question: When Bruce Willis, Julia Roberts and what's left of the gang go to the museum, several people tell Willis how much they liked him in "that one movie". Then they add something like "I knew it when she didn't speak to you in the restaurant". Are they referring to an actual movie?
Answer: The Sixth Sense. They mean that they figured out the true nature of his character when his wife doesn't directly acknowledge his presence in a restaurant.
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.
