Factual error: Before Tom landed in the puddle, there was water dripping or it was raining on it, but it wasn't raining when he was on the rooftops. After Tom landed, the water drops/rain suddenly stopped. Even if the water drops were from earlier rain running off the roof or other parts of the building, they would not be hitting the whole way across the puddle or that far away from the edge of the building. (00:02:34)
Other mistake: Packie arrived at Frank's garage on a bicycle, wearing a brown coat, hat, gray hooded sweatshirt, patterned shirt, and a T-shirt. Swaino arrived on a motorcycle, wearing a tight jacket, no hat, black gloves, and black jogging jacket with white trim. When they were outside by the grill, they had large sweaters over their coats. It isn't known where these sweaters came from. It can be assumed the blanket Swaino used at first was from Frank's garage, but the sweaters did not appear to be Frank's. (00:25:32 - 00:37:35)
Continuity mistake: Although the amount of alcohol remaining in the bottle had been slightly reduced, the reduction was too negligible to have filled the Game Master's glass to the level shown after his telephone call to Sienna. (00:06:57 - 00:08:46)
Revealing mistake: At Wendy's 50th birthday party, the helium balloons did not move, even when her daughter Liz walked next to some of them while carrying a birthday cake with lit candles. (00:01:44)
Other mistake: James supposedly did not give his name when he filed a complaint against Dr. Clark, which would make conducting an investigation to determine if the complaint was valid very difficult. Dr. Clark would be entitled to due process (presumption of innocence) and it is highly unlikely that the Medical Commission would have taken such quick and drastic measures against Dr. Clark under the circumstances.
Other mistake: Liam Neeson jumps into ice water to rescue his brother. He then painfully pulls his brother into the cab of the truck. Inside, he revives his brother after which they have a lengthy conversation. Liam's Mike McCann never starts the truck engine or turns the heater up, even though he and his brother are soaked to the skin and the brother is coughing up ice water from his lungs. In the next scene, both appear dry, in the same clothing, with no signs of hypothermia.
Continuity mistake: The height of the stack of magazines on the coffee table in front of John changes with the camera's view. Front views of John show a high stack of maybe 15 magazines. Side views of John show a much shorter stack of several magazines. (00:25:03 - 00:26:07)
Factual error: The Black Watch sergeant major wears a crown over three chevrons, which was the correct rank badge for a company sergeant major until 1915. However, this is at least 1916 (as conscription has started and the men are wearing steel helmets, both introduced in 1916). CSMs had been redesignated as warrant officers in 1915 and now wore a crown on the lower sleeves instead.
Factual error: Teenagers Claire and Fiona would have been carded and not permitted to enter the "Saints and Sinners" bar because they were under age 21, but they were able to sit at a table and get served alcohol. (00:51:37)
Other mistake: It isn't clear if the poster of the Solar System outside the school was cut off on the right, showing half of Neptune, or if the ninth planet at the time (Pluto) was accidentally omitted. IF the poster was supposed to be complete, its exclusion of Pluto would be an error for the time period (1969) because Pluto was not downgraded to a "dwarf planet" until 2006. Perhaps, only half of Neptune was shown in order to not have to address the changed status of Pluto, making this a deliberate mistake. (00:32:36)
Suggested correction: Neptune isn't cut off, it shows as a complete circle on the "poster" (looks more like a board).
Character mistake: Immediately after kissing (through masks) and having close contact with JJ, Valeria removed her protective mask and went to check on her sick/crying child. Valeria was clicking her tongue, kissing her child on the face/head and putting her hands around the child's ears/hair. Valeria did not take appropriate preventive measures for contracting and/or spreading COVID-19. (00:18:40 - 00:19:29)
Revealing mistake: The "unnatural seam" (line) across Jimmy's forehead and beyond - as well as the overall appearance of his head - indicates that he is NOT "naturally bald"! His "fake" bald head was not put on nearly as well as those seen in numerous other movies. [The actor playing the character does not have much hair in real life, but he also doesn't have that artifical line across his forehead.]. (00:07:13)
Revealing mistake: The blemish/mole that was on the right side of Ghost's nose showed up on her left side (and she was not looking into a mirror). (00:57:40)
Revealing mistake: After Charlie talks to Emma in Francine's old bedroom and is standing in the doorway, the background (segment of the hallway) is obviously fake. Shown are less than five of the top steps on the staircase, only a fraction of the size of real steps. The lower section of the banister is also a reduced size. (01:31:35)
Continuity mistake: After Spencer is tackled to the ground, his black mask keeps changing positions in every single shot.
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)
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: Chris had strands of his bangs hanging down on his forehead but not a second later when the camera panned to a wider view to include all the group of employees. (00:30:44)
Factual error: Some of the set props are too out-dated or obsolete to be included in a science fiction movie set in the "near future" where an android companion costs $40 million, there are various technological advances, and the "God 2.0" system has an "eternal battery life": e.g, rotary phones, old-style bulky CRT TVs, radiator wall heater, camcorder, key-start cars without navigation, old radio, wind-up alarm clock, hand potato masher, old huge headphones, stacks of books, table fan, "rabbit ear" antenna. (00:02:48 - 00:06:54)
Suggested correction: First, this is in no way a factual mistake. Second, it's only your opinion that the props are out of date or obsolete. At best, you could submit a stupidity mistake for a certain character using a specific outdated piece of technology despite having advanced technology everywhere else. I know people who play videos games on a PS5 and an original NES. Why wouldn't they play an outdated gaming system?
Continuity mistake: The bull horns and skull attached to the front of Doug's SUV were much larger on his way to the site than when he pulled up to the meeting spot. Initially, the horns spanned past the low beams, but were some distance from the low beams on each side when he arrived. The overall size of the skull was noticeably smaller and looked less menacing. (00:20:03 - 00:20:35)
