Day 4: 2:00 P.M.-3:00 P.M. - S4-E8
Continuity mistake: When Curtis Manning is chasing Mary-Ann Taylor out of CTU, you see Mary-Ann exiting through a solid grey door marked by an EXIT sign in a wall which looks like concrete. As she passes through the door, you can see sunlight on her from almost directly above. In the next shot Mary-Ann is seen exiting through a glass door in a wall of glass panels. Unless there is a section of CTU's roof missing, the room she exits from in the second shot is not the room she exits to a few seconds earlier in the first shot.
Day 3: 11:00 A.M.-12:00 P.M. - S3-E23
Continuity mistake: In the scene where Wayne and Fox are in Sherry's house searching for the pill container, right before Sherry asks, "What's going on here?" Wayne is seen wearing latex gloves. The camera then cuts to Sherry. When it cuts back to Wayne, his gloves have magically disappeared.
Day 7: 7:00 AM - 8:00 AM - S7-E24
Continuity mistake: In the season finale of 24: Day 7 when Tony is torturing Alan Wilson and Jack comes in and shoots Tony in the shoulder, we can see Wilson raise his hands while lying on the floor with his legs to his left. Wilson remains in this position when Jack shoots Tony in the knuckles. Directly after the shot of Jack shooting Tony in the hand, we can see Wilson sitting cross-legged. With the time elapsed, he had no time to change into his position that quickly. (00:19:50)
Day 4: 8:00 P.M.-9:00 P.M. - S4-E14
Character mistake: In the scene where Chloe uses traffic video to get the license plate number off the van that takes Jack and Dina Araz to Habib Marwan, Tony is seen calling the field teams with the plate number, saying that it's "Charlie-Victor Alpha-Three-Two-Two." But the plate reads "6CVA322" so he should've said, "Six-Charlie-Victor-Alpha-Three-Two-Two."
Day 7: 6:00 AM - 7:00 AM - S7-E23
Plot hole: The head scientist tells Tony that they need Jack's organs to reconstitute that pathogen since there is not enough of it in the sample. Assuming it's a virus, even a small sample could easily be grown in the lab to yield large amounts of the virus. Assuming it's a prion, they don't even need a sample since the could simply build it again from scratch so long as they knew the protein sequence (which is a likely assumption). In either case, Jack is unnecessary.
Day 2: 6:00 A.M.-7:00 A.M. - S2-E23
Other mistake: When President Palmer is at District Headquarters, he addresses one of the workers as "Heather," but the character is credited as "Linda."
12:00 Midnight-1:00 A.M. - S1-E1
Continuity mistake: Kim Bauer has a full set of glittery pink disco nails on episode one (midnight) but then these are not visible at all in most episodes. In the 2pm episode her nails look clean/natural in nearly all the shots, apart from during the phone call with Rick where traces of pink glitter can be seen. I know she's had a very rough night but it doesn't explain the amount of damage her nails have sustained.
Day 3: 7:00 P.M.-8:00 P.M. - S3-E7
Character mistake: At 07:03:05 PM the man pointing the gun at Jack is right-handed, but he aims with his left eye, which is his weak one. He keeps his right eye closed as he walks away and no longer needs to aim, which is a dead giveaway he has never used a gun before.
12:00 Midnight-1:00 A.M. - S1-E1
Character mistake: When Jack subdues Mason he proceeds to check his pulse to check Mason is still alive. When taking the pulse however Jack uses his thumb. This is not how a pulse is checked, as the thumb has it's own pulse and would therefore give Jack's pulse instead of Mason's. Being ex-Delta Jack would know this and not make the simple mistake. (00:22:10)
11:00 A.M.-12:00 Noon - S1-E12
Character mistake: When Jack mentions the siege at Waco, he implies that the ATF's raid failed because an agent on-site screwed up. Their plan had actually been shot before the assault team even reached the compound; a reporter inadvertently compromised their advantage of surprise when he got lost and asked David Koresh's brother-in-law for directions, providing the Branch Davidians ample time to arm themselves in anticipation of self-defense.
11:00 P.M.-12:00 Midnight - S1-E24
Other mistake: As David is walking away from Sherry, there is daylight flooding into the ballroom, just 20 minutes before midnight. (00:32:30)
Audio problem: When Jack is getting suited up, the new bloke arrives and we hear him put his case down on the glass desk. Camera changes and we see him put the case down on the desk a second time. (00:12:50)
Suggested correction: You can see George (replacement to Alberta) holding 2 briefcases just before Jack sits down to put his shoes on.
Day 8: 12:00 P.M. - 1:00 P.M. - S8-E21
Character mistake: When Chloe is talking to Arlo about the call Jack made to Meredith Reed, Chloe says that the call was made to Meredith's cell phone. But at Meredith's office, a coworker tells her the call is waiting (implying Jack called the office instead of Meredith directly), and once in her private office, she picks up the receiver of her land line. With all the phone tracing technology CTU has at its disposal, Chloe should be able to distinguish between the two.
Day 2: 2:00 A.M.-3:00 A.M. - S2-E19
Continuity mistake: In the "Previously on 24" segment, after obtaining the memory chip, Jack says "We got the chip." In the previous episode, however, he says "We got it." (00:01:15)
Day 6: 10:00 PM - 11:00 PM - S6-E17
Continuity mistake: After the staged vehicle crash and shootout, Jack is riding in a vehicle with agent Doyle. It is very dark during the fake shootout; but once the scene changes, daylight is seen through the window of the vehicle Jack is in.
Other mistake: During the explosion from the tape recorder, there is a very short explosion shot recycled from a previous season (when Christopher locks Jack in a bunker and tries to kill him with a bomb placed in a clipboard). This old footage is also seen when that tape recorder explosion is shown on recaps of the event in season 6.
Day 7: 5:00 PM - 6:00 PM - S7-E10
Audio problem: When Dubaku sees Jack and Renee closing in on his car, he tells his driver "Go! Go!", but his mouth doesn't move. (00:09:05)
Day 7: 7:00 PM - 8:00 PM - S7-E12
Continuity mistake: In the split screen of General Juma talking to Jonas Hodges on the sat phone, Juma's jacket sleeve covers his watch in the left box, but not in the right one. (00:29:00)
Day 7: 11:00 PM - 12:00 AM - S7-E16
Continuity mistake: When president Taylor asks Olivia to be her acting Chief of Staff, Allison rests her head on her hand, with only her elbow on the couch. In the next shot, her arm is suddenly resting on the couch instead. There's a straight cut between the two shots, so she didn't have time to move. (00:10:55)
Day 5: 8:00 PM - 9:00 PM - S5-E14
Other mistake: When Jack enters the empty hotel room of Colette and Theo, a chair is rolling across the floor to the right of the screen.
