Revealing mistake: There's no doubt that Joey and his mother were not real kangaroos, but there wasn't even an attempt to make them look at least semi-real with animatronics or better CGI. The kangaroos' appearances were more along the line of what would be expected in a cartoon or all-animated movie. (00:01:00)
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: After the HEAVY rain and losing his supplies during the storm, Max (Royce's adolescent son) told his sister he needed to find two very dry pieces of wood to be able to make a fire. Everything in the woods would have been soaked, but Max quickly found two "very dry" logs and was able to make a friction fire (in record speed).
Continuity mistake: The glass of Charlotte's orange-coloured drink fluctuates between about three-fourths to two-thirds full, including suddenly changing when she merely starts to bend over to pick up a utensil. After Charlotte drinks some, reducing the level to two-thirds, it goes back up and down. Wider views tend to be at the three-fourths level. (00:21:35 - 00:23:02)
Continuity mistake: Joe has 'Rick C' (his partner) listed as a contact in his phone - late on in the movie when Joe calls him from the bathroom stall, he is listed as just "Rick"
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)
Continuity mistake: After talking with Bullock on the roof, Batman is in his vehicle and talking to Hugo. On the screen, Hugo lifts up a glass to his mouth to take a drink, but when the camera cuts to a close up of the screen, suddenly his arm is lower, and he is once again lifting the glass to his face. (00:05:37)
Continuity mistake: The appearance of young JR's hair has many inconsistencies. For example, JR's parted bangs (on the left) are long enough to hang part-way into his right eyebrow while he is walking toward the bedroom, but his bangs are well above his eyebrow when he is standing in the bedroom doorway. When JR is in bed that night, his bangs are separated along the right side of his forehead, but neatly combed together (no gaps) after a camera shift and contrary to gravity. (00:05:10)
Continuity mistake: The amount of red beverage in June's bottle changes several times, from up to the curved part of the plastic bottle (lower amount) to below the neck and up to the neck (almost full). Front views of Mikey show the level of the drink higher than views toward June. (00:17:07 - 00:18:51)
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)
Character mistake: During the opening fight Jackie lands a punch on her opponent just after the round ends. The referee should've warned her about this as it's illegal in MMA to do this, and he didn't.
Other mistake: While Snake Eyes is fighting at the beginning of the film, the other guy throws him to a block of concrete. Snake hits on his head and should be dead by then or at least seriously injured.
Visible crew/equipment: When Rachel arrives home in a blue car, the shadow of the filming crew is reflected on its side. (00:41:15)
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)
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.
Factual error: James called the "Washington Board of Psychiatry" to file a complaint against Dr. Clark (Philip). Complaints (which need to be WRITTEN) against medical doctors are filed under a State's Medical Board, which would be the Washington Medical Commission in this case. Washington has a Board of Psychology and there is a Washington Psychiatric Society, but there's no "Washington Board of Psychiatry" per se (and even if there were, a complaint would still be filed with the Medical Commission).
Continuity mistake: Mia holds her doll's face next to hers, but the doll is not there when the camera shifts. The doll is to Mia's side on the bed, but instantly back next to her face. (This is independent of the times Mia moves her doll.) (00:02:25)
Revealing mistake: After the coach [Michael Jai White] told Billy that the group of people present all chipped in to pay his entry fee, there was loud cheering ("Yeah!) but it wasn't obvious from where the cheering was coming - except when there was a close-up of a particular person. Otherwise, the people in the crowd - especially those closest to him - did not appear to be cheering. The cheering, as well as the people in the background (green screen), must have been added. (00:04:08)
Plot hole: A real estate agent would first ask a prospective home buyer what price range he was interested in and calculate "how much house" he could actually afford to buy before taking him to look at available houses. Austyn took Jim to see multi-million dollar houses, then Jim told her he was "looking in the $250,000 range." Austyn told Jim they could close at $2.5 million and he'd only need 10% down. The 10% down ($250,000) equaled the total amount that Jim wanted to pay for a house. (00:14:03)
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)
