Continuity mistake: When Jack drives to 18166 San Fernando Road he stops the car, gets out and leaves his phone in the car - you can see the green light of the phone's screen - he didn't reach for it. However, when Teri calls him, he has the phone in his pocket.
Continuity mistake: The 6:00PM-7:00PM episode ends when it is still light outside. The 7:00PM-8:00PM episode begins when it is completely dark (no sunset/dusk/twilight) The show is supposed to be in "real-time" but as the sun goes down it gradually gets darker, it does not just become dark from one second to the next. Also, the California presidential primary takes place in June. It is not even close to dark at 7pm in June.
Continuity mistake: When Jack stops at the bus station to get a bag, we see a shot of Jack's car from the point of view of the guy who has the bag. You can see a quite big camera inside the car on the left side. When we see the reverse shot from inside of the car, the camera is gone. (00:05:55)
Continuity mistake: During season one of 24, Jack answers his mobile to Gaines and we see footage of Jack on a CCTV camera. The CCTV footage shows medical staff moving, yet when they cut back to the camera in the hall the medical staff are in different places, they keep changing places and keep disappearing and re-appearing and the CCTV footage is about two seconds ahead of the footage in the corridor. (00:31:00)
Continuity mistake: In the previous hour, Pattie has long straight hair down to her shoulders. We see this all the way through, even at the very end. Yet at the start of episode 22, when she is now at the party a mere 10 minutes later, her hair is very much shorter. There is no way she would be able to get ready for the party in that time, let alone have her hair cut.
Continuity mistake: At about 2:15am, when Jack's talking to Nina about the passenger list on the plane, we see a shot of Jack in the top left, and Nina in the top right. Because it's real time they're both meant to match up - we're watching them both at the same time. In each shot we can see the back of the other's head, but while Jack is looking down and around in the left-hand shot, in the right-hand shot his head is staying perfectly still. (00:15:51)
Continuity mistake: When Senator Palmer is binding his tie in front of the mirror, he pulls the broad part of it completely through the loop of the tie around his neck. Than it cuts to a close-up and the broad part's part-way through the loop again. (00:30:05)
Continuity mistake: In the shot near the end where you see Jack's family running away from the van, Kim is wearing sneakers. But until now, making abstraction of the other continuity error a few episodes earlier, she was wearing sandals. It can be seen in another scene afterward. (00:39:40)
Continuity mistake: The show claims to be in real time, and although those viewers who aren't too eagle-eyed will argue that it is, there is undisputed evidence in this episode that it isn't accurate. After the final ad break, the clock reads 03:52. At least two minutes later, when we see Teri and "Alan York" turn a corner in their car, the clock is displayed at the bottom of the screen, and it is still 03:52. The same sort of thing happens earlier in the episode, when there is a good ten minutes or so between when the clock says 03:26 and when it says 03:30.
Continuity mistake: In the police station, Kim's right arm is handcuffed to the bench as we see the profile/ master shot of her and Rick, but in the next shot, (the medium/front), Kim's right arm is behind her now and not cuffed, as Rick is being cuffed to the bench. A few seconds later, her right arm is again handcuffed to the bench. Kim's right arm is moving around as she talks to Rick and the scene progresses. Her left arm is finally uncuffed when the detective goes to book her. (00:06:20)
Continuity mistake: When the CTU units arrive with the helicopter, they ask Teri to drop the weapon. She puts down the weapon, than it is a cut to a view from behind Teri and she still has the weapon in her hand, but is starting bend to put the weapon down.
Continuity mistake: In the 08:00 - 09:00 episode on DVD (and during the previous few hours) you see Kim Bauer's feet and she is wearing sandals with no socks. At 08:36 when Terri has just been taken from the room where they are being held captive you see a shot of Kim sitting down and you can see that she is wearing pink leather slipper style shoes and black socks.
Continuity mistake: When Keith Palmer and Carl Webb meet they stop walking around to talk. When we see Carl's face, the sun is coming from behind him, the light shimmers through his hair and the light reflects on Keith's face. Than it cuts to a view from behind Carl, and there is suddenly no light, both stand in the shadow. (00:34:00)
Continuity mistake: In the scene where the CTU tactical team arrives at the 'lz', the chopper that first makes ground contact is marked "CTU-1", and offloads six federal agents in full tactical gear. Later in another shot of the same scene, you see "CTU-1" marked on a second chopper still circling in the air. It's clear this is not the same chopper as before, as we see the first "CTU-1" on the ground again moments later.
