Continuity mistake: Cross is about to shoot at the window of the train to break it; he is holding on to the vertical bar of the cart with the thermos hand, but the bar is gone in the closer view. (01:10:20)
Factual error: Outside of the house of Senator Rose are police cars of the Barcroft County Police. The police for Lake Barcroft are the Fairfax County police. (01:01:15)
Continuity mistake: To enter the Rose residence with the boot courtesy of Soneji, Cross shows the Fed at the door his badge with his left hand, that becomes the right at the cut. (00:18:45)
Continuity mistake: In front of the embassy, the driver's window jumps several times from being quite open, to closed (during the U turn) to less open (during the shootout). (00:58:00)
Continuity mistake: Jezzie points the gun at Devine's throat. When she begins laughing, she lowers the gun, which is still all the way up pressing to his jaw in the reverse shot. (01:24:00)
Continuity mistake: Cross tells the agent at the gates "I've been invited", and the man opens the door pulling it by the handle, which becomes the top of the door at the cut. (00:18:55)
Continuity mistake: Cross is at Union Station, and hears a public phone ring. When he dashes across the entrance, the passersby change between shots. (01:07:35)
Continuity mistake: Cross is making a model ship. Vickie makes a joke about being "ship-shape"; at cut, she has in her mouth a spoon she did not initially have. (00:12:30)
Continuity mistake: Dimitri hands Jezzie the knife between the gate bars; he is holding it in two different ways in the two shots. (00:59:35)
Continuity mistake: Jezzie pours the diamonds from the thermos into her left hand. In the close-up, she is pouring them again. (01:25:30)
Continuity mistake: Devine's cigarette burns half an inch the moment he turns the TV off (and we switch to the close-up). (01:23:05)
Continuity mistake: Megan takes Soneji's cup with her left hand, but drinks in the reverse shot with her right. (00:26:05)
Revealing mistake: There is a mistake in the (quite dodgy) CGI when the car tumbles down into the dam in the opening scene. At one point, the camera cuts and we can see the car bouncing downwards through the air, and there's a splash of water from where the car bounced off the wall of the dam. But if you pay attention, the splash of water simply vanishes/fades away about two seconds later. Sure, if it was more of a fine mist, it'd make sense that it'd lose visibility, but these were huge streaks of water that should still be visible for quite a bit longer.
Continuity mistake: The first time we see her, Jezzie is talking to Megan. She is holding her clipboard with the hand placed underneath it or above it depending on the angle. (00:05:40)
Plot hole: Devine is in the hideout. It is late evening/night. Nothing in the timeline here makes sense. For starters, the newscast says that "over a week ago" the manhunt for Soneji started. Cross gets on the case the first day, on day 2 they find Mercusio's home, day 3 the failed embassy run and Megan is taken away from Soneji (but nobody knows), day 4 is the jewelry heist, leaving Soneji to be killed the same day or after (the movie messes up on that account but seems to want it to happen the same day, I'd give it another day, making it 5). Moreover, it says that Soneji was killed late in the afternoon the day before; it means that Jezzie waited more than a whole day to go to him, and Devine's comment about the kid being so doped up she didn't realise she is not on the boat makes no sense when it implies she'd have to sleep for 2 days straight instead of one. (01:23:00)
Continuity mistake: After receiving instructions from Mercusio (when Cross is told to go to the Watergate), agent Ollie McArthur says "okay people, let's move." He says that across two shots; in the first, Monica Potter is distinctly shifting her eyes from looking in front of her to looking to her right, but in the second she is looking straight again, making the lack of continuity quite obvious over such a small detail. (01:03:50)
Continuity mistake: Jezzie's computer that she used for all her operations has the screen seemingly turned on, always of a bright blue even before Cross actually switches it on. When he looks at the password screen with just 'Administrator' as username, the screen is black, like it is not in any other part of the scene. (01:27:40)
Plot hole: There is a massive problem in the timeline of the movie, starting when the 'running game' is set. It is dawn when the kidnapper contacts the family and the police. He says, that he will call back in 9 hours, and even says "4 PM sharp." The events unfold, and Cross is on the metro train during rush hour, firing his gun. But at the press conference that follows, agent Ollie McArthur declines to comment on the "incident on the MTA train this morning." (01:03:05 - 01:10:00)
Plot hole: In her plot convenient computer content, Cross finds the address of the house for lease Jezzie has. The house is located in Lovettsville, Virginia. That means it's over one hour away from the apartment in Washington. If we take at face value what happens in the movie, with Cross breaking into the house once Jezzie has killed Devine, then it's impossible he made it in time to catch her and save Megan. One wonders what took Cross so long anyway to get to the house considering he visited the school that tipped him off about Jezzie when students were still around, and why he does not warn the authorities (which is kinda hilarious since what tips Megan off about Jezzie, is that she came alone, exactly what the hero does!). The timer on the computer screen when Cross finds out is 00:00:00, which is a bit unlikely and not much help. (01:29:00)
Other mistake: Mercusio tazes Jezzie and enters her apartment. Look at the wall clock; the time shown is 4:05, when Cross was barely at the Watergate Hotel at that time. (01:13:00)
