Deliberate mistake: An LAPD cop discharges his firearm a full size Glock which has a minimum magazine capacity of 13+1 for the Glock 21. The Glock 21 is approved LAPD issue along with other variants. He fires maybe three shots and the slide locks back signalling that it's dry. A second later the same cop is walking with the same empty Glock aimed towards the suspect which was shot at. It's visible that the slide is being held back by the slide stop since the magazine went dry. (01:29:58)
Continuity mistake: There are several variations or inconsistencies in Marcus' hair and tie from the time he goes through the metal detector and sits in the courtroom. His hair was consistently "messy", but disheveled right and/or left sides were inconsistent. The tie was fairly snug against his collar at first, but got looser then tighter. (00:54:14 - 00:57:08)
Continuity mistake: When Dave and Meg are at the park/campus talking and come across a sculptor, they begin to talk while stopped, watching. Several times Meg's head changes from looking at Dave to watching the sculptor between shots.
Continuity mistake: Jeffrey downs all his whiskey, but in the following shot his glass is still half empty. (01:35:50)
Other mistake: The Israeli commandos are painting an orange Mercedes black using brushes. In later scenes the car has perfect factory finished black paintwork.
Continuity mistake: Whilst driving back after meeting with Paul Castellano, Gotti has his hand on the driver seat headrest in some shots, but in others his hand is on the seat. (00:35:05)
Character mistake: Immediately after the crash, when Reeves is carrying his youngest child Sophie, the actress opens up her mouth, even though she has already drowned. (00:14:43)
Revealing mistake: Davey at the beginning of the movie is looking at the newspaper he's delivering to Mr. Wayne Mackey. Just from a glance at the page you can tell that something is off, since the article supposedly about a missing boy appears to be written entirely in first person. Upon closer inspection, turns out that it's filler text from chapter IV of Robert Louis Stevenson' s "Treasure Island". (00:01:30)
Factual error: When the saturation divers open the outer hatch on Kursk, they drop a glow stick. When they do, it falls to the floor on the submarine, indicating the inner hatch was open. The inner hatch of Kursk was closed, later opened by an ROV.
Factual error: An ambulance is shown. This movie is supposed to take place in a latin country. But the ambulance says "Ambulance" in English, and worse, it also says "Riverside County." Also, the red cross emblems on the attendants' backs say "Comite" in Spanish, "International" in English, and "Geneve" in French. (00:28:55)
Factual error: Second scene, caption says "1977 southern California" but she's driving a white 90's Oldsmobile Cutlass Ciera Fwd station wagon.
Continuity mistake: Susan meets backstage Dr. Mitch. He states the obvious saying that she looks alike her twin sister, just more confident, and she cuts him off saying that she knows. She was leaning back with her hands as support, and at the cut she replies to him with her hands joined at the front. (00:09:45)
Continuity mistake: In the first WW2 flashback the protagonist is handing the various items to the Nazi doorman. When he puts down the pen, he is doing it with a left hand in the table close-up, but he picked it with his right, as the left arm is busy holding the coat. (00:02:05)
Continuity mistake: In Alice's apartment the clock on the wall has the time as 8:40 when she is standing and kissing David. They have sex and Veronica comes over. Alice and Veronica talk and the clock still shows 8:40. (01:20:00)
Revealing mistake: After Frank shoots Kevin and Kevin's SUV hits the curb, the background/scenery changes as well as the position of Frank's car. Frank initially pulls along the curb (behind the SUV) with his car at about a 30° angle. The next time Frank's car is shown, it is almost perpendicular to the curb and the Food Mart. When Rupple and Frank have their guns aimed, they would be aiming inside the Mart, not toward Kevin. Objects in the background also change (e.g, fire hydrant, telephone pole appear). (00:16:48)
Continuity mistake: Abby's annoying boss puts her friend to work giving him a box to carry to his car. In a rather blatant continuity mistake, the penguin is facing opposite directions between shots. (00:03:15)
Continuity mistake: Violet's mom is hot combing her hair at 5 AM; as she performs this operation on the left side, the right side has straight black hair all in front of the shoulder. When Violet tells her that dad is coming, she moves to the right side. Sanaa Lathan's hair now is suddenly all behind the shoulder. (00:05:20)
Continuity mistake: The position of Don's baseball cap on the table changes two times. Initially, the cap is near the corner of the table with the visor and letter "P" roughly parallel to the front of his body. After he pours beer into his glass, the visor is angled more toward the corner of the table (even though the camera appears to pan around it). When Don brings Mike back to the table, the cap visor is pointed toward Don and is at a differently angle (more parallel to the front of his body again). (00:00:09 - 00:01:47)
Continuity mistake: At night, as Claudia gets into bed with Rory, we see her bare back across the shoulder blades, and no evidence of shoulder straps. In the morning she awakens with surprise at Rory's absence, and she is wearing a top that would have been visible if she'd worn it in the night scene. (01:31:13 - 01:33:00)
Factual error: Michael boards a commuter train at Grand Central, which then stops at subway stations at 68th Street, 86th Street, and 110th Street along Lexington Avenue. This is impossible.
