Day 8: 9:00 P.M. - 10:00 P.M. - S8-E6
Factual error: The bad guys talks in German to Jack Bauer, posing as a German weapon dealer. But the German dialogue is very hard to understand, full of errors and with heavy accents - especially from Jack. After the first sentence his cover would be blown. (00:32:40 - 00:33:15)
Day 4: 10:00 P.M.-11:00 P.M. - S4-E16
Character mistake: 23rd minute. Jack meets the female assassin in Anderson's apartment. She demands that he show his credentials. Jack says he's with CTU on a provisional basis and therefore he has no badge. The agent that came with Jack confirms that. Yet, in the 13th episode (minute 14) when he enters the sports shop with Audrey's husband, he shows his CTU badge to the owners in order to prove that he in fact is a federal agent.
Jack Bauer: I've killed two people since midnight. I haven't slept in over 24 hours. So maybe you should be a little more afraid of me than you are now.
Question: Did the actress who plays Nina know the entire time that she was supposed to be bad, or was this written into the show mid-season?
Chosen answer: Nobody knew, not even the writers, until at least halfway through the season when they were writing the end. They wanted to keep all options open.
