Character mistake: The computer technician sitting at Megan's desk is "scoping" (her software is in "scoping mode"!) the GIFs the kids have been using to exchange information. Telling Cross what the name means, she says it stands for "Graphics Interchange Formats", while it is Graphics Interchange Format, no S. She also talks about "billions of 0s and 1s" making each image, which would mean billions of bits, which would mean the kids are casually exchanging 100 MB gifs, which are not so likely nowadays, and even less in 2001. (00:31:55)
Continuity mistake: Cross found out that the picture missing is Charles Lindbergh's (like the blackboard says). He says then "Our Mr. Soneji has a sense of humor." The IT agent by him has her arms folded, hands visible at the elbows. Close-up on Morgan Freeman, and her hands are not on display anymore. (00:35:50)
Continuity mistake: Alex Cross is in front of a computer screen, checking out images of the class to spot the missing picture. From behind, Morgan Freeman is in pose with his finger on his temple, then lowers his hand and turns around. In the next shot, he's still holding his hand high as he is turning. (00:34:50)
Continuity mistake: At the press conference, McArthur is going full "no comment" about pretty much anything. A grim Alex Cross is standing there. Next to him are the senator's wife and the senator. At the cut the senator disappears, leaving just the wife and the FBI agent. (01:11:10)
Character mistake: Cross knows (for some reason) by memory the last words of the Lindbergh kid kidnapper (and killer) and that Soneji/Mercusio referenced in a book he finds in amazingly oblique ways. He calls him "Richard Bruno Hauptmann", while his name was actually Bruno Richard Hauptmann. (00:42:30)
Continuity mistake: Cross begins his running game with the kidnapper. He says "I'm on my way to Sixth and Pennsylvania.", to which Jezzie goes "I'm left and behind ya, Alex." She is from behind using her right hand on the steering wheel, but she has the left on it in the following shot. (01:05:40)
Revealing mistake: At Mercusio's place, Cross is checking out a variety of material the maniac collected on Cross himself. Which include newspaper clippings but they're all the same one, by "Lisa Francescato", same article repeated, just omitting the first short paragraph the second time. (00:39:20)
Continuity mistake: The principal is trying to open the door of Soneji's office, but she can't. She is lowering the hand with the key and turning as she is told to "Stand back", but when Jezzie pulls out of the gun she is still hunched over with her hand on the key in the keyhole. (00:11:20)
Continuity mistake: Cross is talking with Jezzie in her apartment, holding several sheets. The sheets are at the same height in a certain camera angle (when he says "You do what you are", and then "you were born with a gift"), despite the fact that meanwhile he moved those sheets around. (01:12:10)
Continuity mistake: Mercusio gets back to his boat after the embassy fiasco. His shirt is wet in the middle, down to the pockets on his chest, both sides. He grabs his gun and goes to Megan's cell, but his shirt, in the space of few steps, dried considerably up on his right side. (01:01:25)
Continuity mistake: Cross missed the phone call from the payphone at the station. In close-up, Morgan Freeman's hand is on top of the phone, fingertips on the horizontal side. New angle, and now he is leaning with the same arm, but the hand is relaxed, draped over the round corner. (01:07:50)
Other mistake: The software the FBI agent is using to decrypt the "Stego-encrypted GIFs" says "ANOMALLIES FOUND; TRUE", with 2 Ls, and closes the report with a pretty worrisome "EXRTANEOUS POGRAM FOUND; TRUE." (00:32:30)
Continuity mistake: After Mercusio's home invasion, Jezzie's ice pack turns around in her hand between shots (you can make out of the way it is pointed in the first shot when the paramedic is still checking on her; some letters are visible at the end, and they are turned straight). (01:19:40)
Continuity mistake: In the close-up when she falls dead on the floor, the cable used to strangle the teacher is under her head. When a few seconds later Soneji is shown opening the panel of fake computers, she is lying dead with the cable in a big loop in front of her face. (00:10:05)
Continuity mistake: Soneji tells Megan "Come to my office"; in that shot you can see a teacher walking down the corridor towards the camera, but she had already reached a closer point by the security agent in the previous (when Soneji was blowing his nose). (00:08:00)
Continuity mistake: Jezzie kicks the door open and in the close-up we see the strike plate and a strip of wood wave in an ample motion, broken. When she is walking into the room, door still opening, the doorframe is completely still, no metal or wood still shaking. (00:11:30)
Other mistake: In the sequence in front of the embassy when Jezzie runs towards the police car as it escapes, in the background Morgan Freeman's stand-in 'surrender' to the Russians way before the real Morgan Freeman does it in a close-up. (00:58:50)
Continuity mistake: In the moments preceding Mercusio's instructions to board the train, Jezzie looks towards Cross. She is almost on her own on the platform, but in a close-up on Monica Potter, more and different people are suddenly present by her. (01:09:05)
Continuity mistake: Cross is cheering Jezzie up for missing her chance to stop Mercusio. He says "If you hadn't convinced me to stay there", and is gesturing with the left hand on the table...which turns into the right hand at the cut. (01:02:05)
Continuity mistake: On the train, Jezzie says "Get down, everybody down", the two women with dark coats behind her get down twice in different ways - one is even holding a newspaper in the second shot that she did not have before. (01:10:20)
