Continuity mistake: When Norton gets the passwords for the new cameras at the park, there are three passwords. The first and the second have three digits, but the third password has four digits. But when Norton types the three passwords, the sound was for three passwords of three digits.
Continuity mistake: Near the end when Ed Norton's character changes and gets ready to leave with the gold staff, he puts the bag with the gold over his back first and then puts on his backpack. Later, when you see him running to the bus station, you see that the backpack is against his back and the bag with the gold staff is on top. This is also evident when he is talking to Robert DeNiro's character and he takes the bag with the gold off first.
