Day 6: 8:00 AM - 9:00 AM - S6-E3
Visible crew/equipment: After Tom tells President Palmer that Sandra has been arrested, when it cuts to the interior shot inside the car with Agent Samuels in the front passenger seat, the camera pans toward the rear passenger window showing all the protesters outside. In this shot there's a reflection of the camera operator's leg, wearing shorts, white socks and sneakers, and who is sitting where Sandra should be.
Day 6: 8:00 AM - 9:00 AM - S6-E3
Visible crew/equipment: When Jack pulls over at the side of the road, as he informs Curtis that Assad is two miles ahead on the service road, the red T-mark is visible on the ground where the two men will stand.
Day 6: 9:00 AM - 10:00 AM - S6-E4
Revealing mistake: When Jack is forced to kill Curtis, Roger Cross flinches before the sound of the gunshot. (00:36:35)
Day 6: 12:00 PM - 1:00 PM - S6-E7
Continuity mistake: At the very end of the previous episode (approx 11:59 AM), Jack and Phillip are chained at the back of the van, and in the closeup Jack's handcuff double bar faces up on his right wrist. This moment is shown in the recap at the start of this episode. When the van reaches the dump site (approx 12:07 PM), Jack and Phillip are unchained and now Jack's handcuff single bar faces up on his right wrist. (00:01:55 - 00:07:55)
Day 6: 2:00 PM - 3:00 PM - S6-E9
Visible crew/equipment: When Jack and Marilyn's car pulls up to 9407 Hindry Place, with the tactical van behind them, the filming crew's vehicle's license plate, beginning with 9DGE, is reflected on the car's windshield. (01:11:20)
Day 6: 2:00 PM - 3:00 PM - S6-E9
Continuity mistake: When Milo begins to drive the tactical van with Marilyn, the driver's side door acquires significant damage, but when being shot at a moment later, the door is undamaged.
Day 6: 3:00 PM - 4:00 PM - S6-E10
Visible crew/equipment: While Bill, Nadia, and others begin watching Turner's team move toward Gredenko's presumed location on the live video feed, in the next shot facing Bill and Nadia, the T-mark quickly becomes visible at the bottom of the screen, near Bill's feet. (00:29:50)
Day 6: 6:00 PM - 7:00 PM - S6-E13
Continuity mistake: When Logan walks into Martha's bungalow, there is a deliberate close-up of the photograph with Martha and Anya, in a narrow goldtone frame. Oddly, in following shots, that photo is in a wide width, white frame. Additionally, the arrangement of all the frames on that table changes quite a bit as well.
Day 6: 6:00 PM - 7:00 PM - S6-E13
Continuity mistake: When Martha stabs Logan in the first shot, she drops the two plates she holds in her left hand. Next shot, facing Logan, the two plates are still in her hand.
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.
Day 6: 12:00 AM - 1:00 AM - S6-E19
Visible crew/equipment: After Tom tells the VP that he could authorize ancillary agencies to join the search to find Jack, he and Karen leave the Oval Office, and in the next shot facing Lisa as she walks toward Noah, the yellow T-mark is visible on the rug at the bottom of the screen. (00:11:05)
Day 6: 1:00 AM - 2:00 AM - S6-E20
Continuity mistake: When Doyle puts Jack in the holding cell and handcuffs him, the cuff's double bar faces up on his right wrist, but when Doyle uncuffs him shortly after, the single bar faces up.
Day 6: 1:00 AM - 2:00 AM - S6-E20
Continuity mistake: In season four James Heller told Erin Driscoll that his wife, Audrey's mother, was named Susan. In this episode her name is Alicia.
Day 6: 2:00 AM - 3:00 AM - S6-E21
Continuity mistake: After Jack kills the Chinese agent, he picks up the agent's weapon (a HK G36). The weapon has a magazine in one of the camera angles but when the scene switches to another angle, there is no magazine in the rifle. (00:32:15)
Day 7: 8:00 AM - 9:00 AM - S7-E1
Continuity mistake: When Alan Tanner shoots Gabriel Schector, three shots are fired, but four bullet holes are visible in the window.
Day 7: 8:00 AM - 9:00 AM - S7-E1
Character mistake: When Ethan Kanin tells president Taylor that Henry has managed to convince Kevin Aldridge to hold off on his report about the Sangalan invasion, he accidentally refers to the reporter as "Henry Aldridge."
Day 7: 9:00 AM - 10:00 AM - S7-E2
Visible crew/equipment: While FBI agents are searching for the sniper Jack tells Renee there must be a bad agent, and just as he warns her about who she lets in, the green T-mark is visible on the ground. (00:05:35)
Day 7: 9:00 AM - 10:00 AM - S7-E2
Character mistake: Larry Moss says that there are three dead bodies at Gabriel Schector's office, but there are only two: Schector and his bodyguard Ari.
Day 7: 9:00 AM - 10:00 AM - S7-E2
Factual error: Tony Almeida takes control of 2 planes to create a near miss. In reality all aircraft use a commonly available AM voice radio and pilots can hear each other's radio communications. It would be straightforward to contact the planes and warn them.
Day 7: 9:00 AM - 10:00 AM - S7-E2
Continuity mistake: In the "previously on 24" recap, Jack tells Renee Walker "the Department of Justice is about to file criminal charges against me." But in that scene in the previous episode, he used the departmental abbreviation "DOJ".
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.
