Deliberate mistake: In the pitch dark mansion dining room, the approaching zombie's screams are instantly interrupted by silence whenever the flame from Chris' lighter goes out, and then the screams instantly resume when the light returns. While this is obvious artistic license, for the record the level of darkness would have no bearing on whether we can hear the zombie screaming.
Factual error: When Ed and Lorraine Warren are trying to convince the lawyer to represent Arne, there are is a copy of "Jonathan Strange and Mr. Norrel" on the shelf behind them, which was published in 2004. The film is set in 1981.
Continuity mistake: Maddox has blue eyes as a teenager and dark brown eyes as an adult.
Deliberate mistake: Driving to Malibu, Knox's truck is going the wrong direction on the road - the solid double yellow lines are on the passenger's side and the solid white line is on the driver's side. (The driver is on the left side of the vehicle.) There is no solid white line on the opposite side, indicating it is a one-direction road. The truck quickly crosses over the yellow lines and goes off-screen, after which it can be seen there's a wide paved shoulder that tapers to the edge near the intersection. (00:03:20)
Character mistake: At conclusion of Katrina's interview with April, a banner on the bottom of the screen says "Auhtor Katrina shares her real Christmas story". (01:18:48)
Factual error: After Mohamedou's torture scenes, the CO of GITMO holds up a letter from the Dep. Of Defense in Mo's face, stating that his mother had been detained. In the bottom left corner of the letter, it is written as "Department of Defence", which is the UK spelling. (01:41:27)
Continuity mistake: In the desert digging, the Nova's trunk is open, then shut. (01:42:00 - 01:45:00)
Continuity mistake: When Mrs. Krementz talks with Zeffirelli while he's taking a bath and asks her to close the bathtub curtain, the cigarette he previously had in the mouth disappears in the next shot when Mrs. Krementz closes the curtain.
Revealing mistake: The jaguar near the start jumps onto the bar and prowls along it. It knocks over one glass with some force, which shatters, but the second glass is barely tapped by its foot and it smashes to bits too, when it should just have been pushed out of the way.
Factual error: The scope Jim is using is completely wrong (yes I know he tested the wind using dirt) but as a U.S.M.C. Marksman his scope would have had mil-dots on both the horizontal and vertical bars. (00:04:24)
Continuity mistake: An exterior view of the window in the building across the street that the Virtuoso plans on shooting from shows it is comprised of three square panes stacked vertically. When the Virtuoso is inside behind the window, it is one large vertical pane. (00:10:27)
Continuity mistake: When watching the water retreat after Sisu falls, a view from behind the characters shows Noi sitting on Tuk Tuk. The very next cut shows Tong picking her up from the ground. (01:18:01)
Factual error: The telephone for the phone bank doesn't have a phone jack cord connected into the back of the telephone. (01:15:14)
Continuity mistake: When Tae-ho is looking through the briefcase, he picks up a report file with Hyeonu Kang's name on the front. When he first picks up the report, his hands are placed on both sides of the file. In one shot, his hands are positioned towards the middle of the page, but in the next shot, his hands are positioned near the bottom of the page. (00:27:10)
Continuity mistake: While Semmi is telling Akeem about their visits to the nightclubs, there are shots from the original movie with some women they meet. When the "woman" in red tells them she's going to tear them apart, Semmi's wearing a patterned shirt, tie, and blazer when he spits his drink. Two shots later (new footage), Semmi's shirt collar style changes, as well as the pattern on his shirt and blazer. (00:11:15)
Continuity mistake: While waiting for her audition, Finley's blouse is loosely tied above the waist, with two flaps hanging like a bow. When Finley gets onto the platform, the knot is tied tighter in the front and the two flaps overlap (look like one), hanging similar to a short tie. (00:17:05)
Continuity mistake: When Jackson is shot with shotgun he "flies" across the bathroom, hits the wall, and falls into the tub on his right side with his left leg on top of the tub and leaning to right. Next shot he is on his back. (00:26:25)
Factual error: There is a calendar in a scene towards the end of the movie which shows the date as Wednesday April 30, 2021 but the calendar does not align to the days of a real calendar. That date will be a Friday. (01:25:54)
Factual error: The Channel 5 WNP Newscaster said, "it is now believed he [District Attorney Berdido] and his family were killed..." and running along the bottom of the screen was "4 confirmed dead in Fort Lauderdale gas explosion." This was a LIVE report showing two streams of water onto the house still burning inside. An investigation would barely, if at all, be started at this time and no-one would be "confirmed dead" this early. It would not even be known if anyone was home when the house exploded. (00:04:34 - 00:04:55)
Continuity mistake: At the prison visiting "Uncle Sally", Dickie sets a box of matches on top of his cigarettes. A little later, the matchbox is behind the cigarettes and the cigarettes are angled about 45° more away from the ashtray. (00:48:12)
