Background Information and Notes

 * The CTU interior seems to have gotten a facelift since the previous episode. This is due to the fact that the pilot was filmed quite a while before the series was picked up by Fox.


 * The clock noise before and after the commercial breaks has changed since the pilot.


 * Beginning with this episode, the billing of executive producers Joel Surnow and Robert Cochran and co-executive producer Stephen Hopkins have been moved from the beginning of Act I to the closing credits. They're moved back later in 6:00am-7:00am.


 * When Jack Bauer calls Nina Myers from outside the parking garage, he tells her, "I'm at 2350 Dunlop Plaza, the North Garage." However, a few seconds later Tony Almeida calls up a transcription of their conversation onto his computer screen, and there is a close of the part of the text which reads, "2350 DUNLOP PLAZA THE NORTH PARKING GARAGE," even though Bauer said "I'm at," before this, and he never said "parking" in front of "garage".
