Character mistake: In the scene where Bruce Willis, Mary-Louise Parker, and John Malkovich are having lunch outside on a river in New Orleans, right after Mary-Louise Parker gets off the pay-phone, John Malkovich reads off the tail number of a helicopter flying over as "N9745C", even though the number is visible as "N9748C". A few minutes later, when the three are talking to James Rema in Mobile, in the airport control tower, they see the helicopter (again, visible as "N9748C"), only this time, John Malkovich correctly identifies it as "N9748C".

Character mistake: When Victoria is blasting away at the VPs limo, the security truck should block the limo from the machine gun. They just pull up behind it even though that vehicle is specifically in the motorcade to carry agents and to block threats even though it is usually not an armored vehicle.
