Corrected entry: When Martin Harris is attempting to prove who he is in the security office of the hotel, he asks the security to call a colleague. When he gives the number he says, "001.". International calls start with 011, not 001.

Corrected entry: When Liam Neeson opens the multiple passports from his briefcase at the airport, the forenames and surnames of the identities are all the wrong way around.
