Other mistake: Hero drove his car through a line of armored men and crashed onto rocks along a cement wall. Two days later when he returned to his car with gasoline (where one of his bombs exploded by the car), there was smoke and dust blowing through the air all around yet views of his car showed it was perfectly clean - shiny black. (00:52:35)
Factual error: When the hackers take out Zagreb, Croatia, one shot shows the effect on a train in a subway station. Zagreb has no subway.
Continuity mistake: When Billy is walking (from his front porch) to his Jeep, the ground is brown, and he has to take several steps to reach the cargo area. When the camera shifts to a front view of Billy by the driver's side door, and he says, "Hi, coach", the Jeep is parked too close to the house for Billy to have taken that many steps to reach it and the grass behind the Jeep is green (not brown). (00:07:45)
Revealing mistake: The way in which the flame from the fallen candle started burning the wall painting of the family, as well as how the fire spread (rather, didn't spread) and looked, reveal the fire was computer-generated, not real. (00:24:23)
Plot hole: Diabolik blinks in Morse code to his accomplice the location of one of his hidden stashes. He says it's in 'the third brick to the left' and the street name, but no address or other reference. She (who previously knew nothing about the location) finds it immediately. It's worth noting that the movie is a faithful adaptation of a couple issues of the comic, but this bit of subplot is a fresh addition and the original hiding spot in the 1963 issue was a plausible one (cave behind a specific waterfall).
Continuity mistake: Ed Harris plays a property manager character and is featured in the beginning of the movie, walking with a pronounced limp, a seemingly painful gait. His character is shown in many other nominal scenes throughout the movie without limping. Most notable, shortly before the end of the movie, his character is shown dancing wildly, spastically, and jumping to music, seemingly unencumbered and fluidly, in a way that his character in the first part of the movie would not have been capable of doing.
Factual error: When Sharyn woke up after surgery, she did not know how long she had been there, but her abdominal scar was practically healed. Under these circumstances, she should have had a urinary catheter but did not. Also, when Sharyn lifted her gown to look at the scar, she was wearing bikini-like lace-trimmed navy blue underwear - it is unlikely anyone would have put such underwear on her after surgery. (00:05:14)
Continuity mistake: When Hagmaier is in the Florida State Prison room waiting for Bundy, his hair changes. Initially, his short bangs are straight across the middle of his forehead. When Bundy sits down, Hagmaier's bangs and top of head are "fluffier" (perhaps blown dry) and combed to the side. (00:11:05)
Continuity mistake: Max Cameron's classroom appears to be slapped together and inconsistent. The wall is white but later tan. The door hinges are on the right, then left. The pencil sharpener, awkwardly mounted on the door frame, gets moved to the right. The hallway is a tan wall, but later just a closed door. Doors comprise the wall behind Dewey and there's a door behind Max, to the right of the white board. (00:59:55 - 01:00:43)
Other mistake: Jane's top includes a scarf that is wrapped around her neck a few times. She starts to remove the scarf by unwrapping it clockwise. When the camera shifts, and she resumes unwrapping the scarf, she goes counterclockwise. (00:20:55)
Plot hole: Charles was a con man, going up the east coast (Florida and North Carolina) offering to do cheap storm repairs, taking the 50% cash down-payment and moving on (fleeing to the next location). As such, he would try to stay away from police/law enforcement officers and not call attention to himself. Filing (bogus) criminal complaints against Peter put Charles in direct contact with the police - a very risky and stupid move on his part.
Revealing mistake: Scottie (with Jamie) drove away in a blue four-wheeler that had a cab area (front windshield, roof, and four support bars or frame). At times, the four-wheeler did not appear to have a roof, the windshield was not visible, and the frame was gone - indicating they were not in an actual four-wheeler during these filming times. (01:13:58 - 01:16:00)
Other mistake: When the helicopter was flying toward and over Apex Island, the helicopter (as well as the similarly-sized box) was about 1/10 or 1/12 the width of the island. In the next view, from almost ground-level, the helicopter was about as wide as one pine tree. (00:10:30)
Audio problem: Obviously, the mouth movements won't match the English voice-overs, but when Yang Hao is singing "Happy Birthday" to his daughter Yuan Yuan, his mouth doesn't move at all. (00:05:50)
Character mistake: The interviewer pointed out that Evan [Mark Wahlberg] is a "smart guy" and another man later said, "Homeboy knows everything. He's a freak." When Evan was telling the interviewer the circumstances under which he assaulted a man, Evan committed a basic grammatical error - a misplaced modifier: "I asked him to leave politely." Evan didn't mean he wanted the man to leave in a "polite manner"; he meant he "politely asked" the man to leave. (00:09:20 - 00:14:00)
Continuity mistake: There isn't anything immediately in front of the storage shed when Edee opens the door. Inside, looking out, there is some type of diagonal, long thin branches or vines extending to the ground, which are gone in the subsequent view. (00:09:42)
Continuity mistake: The angle of the laptop on the kitchen table changed (and no-one was close enough to have moved it). The laptop was initially more evenly aligned with the edge of the (round) table. A little later, the laptop was not visible, but probably should have been. (00:04:09 - 00:04:44)
Factual error: "The Waltons Homecoming" is a remake of the 1971 TV-movie that led to the 1972-81 television series "The Waltons." In one scene, John-Boy has written a story for The Boston Arts Scholarship Competition. He addressed the envelope to "1815 Redwood St, Boston MA 02122." The movie is set in 1933. The Postal Service did not introduce ZIP codes and two-letter state abbreviations until 1963.
Deliberate mistake: The angle of the light coming from the film projector (which was up high on the back wall) was too high to actually project onto the screen across the room. Also, people were standing in front of the screen and should have been blocking part of the projection and have light on their backs but did not. The screen operated more like a DVD player on a TV. (00:35:20)
Other mistake: At the end of the movie the soldiers handcuff Farid despite the fact that he only has one hand.
