Miscellaneous: After Agent Paulson escorts Teri and Kimberly into the bedroom and tells them to lock the door and wait there, the closed captioning reads, "Mom, I don't feel safe in here." The line doesn't remain on the soundtrack and was presumably cut pre-filming since Kimberly's lips aren't moving when it pops up.
Revealing mistakes: When Milo gives Jack the photos of the three "plan B assassins", the file about Alexis Drazen is in fact a file about Ahmed Ressam (a terrorist convicted for trying to bomb the LA Airport on 1999 New Year's Eve) with the photo of Drazen above.
