Other mistake: When Bruce Willis enters the hotel room in Rome to see Julia, Matt Damon reacts twice with surprise when he turns around and sees Bruce.
Factual error: In the movie the poles which houses are built on are situated in the water; one could swim between the poles. That's totally impossible: the poles are drilled in very wet sand (to be compared to a swamp) and you can't reach them from the canals in any way.
Linus Caldwell: You ever notice that Tess looks...
Rusty Ryan: Ooh, don't ever ask that. Ever. Seriously. Not to anyone, especially not to her.
Linus Caldwell: Wait, why not?
Rusty Ryan: Look, it's not in my nature to be mysterious. But I can't talk about it and I can't talk about why.
Trivia: The scene shot in Amsterdam Central Station was actually shot at the Haarlem train station. Dutch Railway officials didn't allow the interference of trains schedules on such a crowded station, since they're fined by the Dutch government for every delay. Haarlem is much quieter a station and just as beautiful a location. Also the Europol headquarters are in fact the Hague's City Hall.
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.
