Day 8: 4:00 P.M. - 5:00 P.M. - S8-E1
Revealing mistake: When Farhad Hassan brings the press ID for Meredith Reed to security, you see the guard walk through the metal detector wearing his police belt, but the metal detector does not go off, showing that it's either not real, or not turned on.
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.
Day 6: 6:00 AM - 7:00 AM - S6-E1
Jack Bauer: Do you understand the difference between dying for something and dying for nothing? The only reason I fought so hard to stay alive in China was because I didn't want to die for nothing. Today, I can die for something.
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.
