Factual error: Dylan (Scott Eastwood) was in a jail cell yet had a bottle of prescription pills in his pocket. The pills would have been confiscated before he was put in the cell and administered to him on schedule by staff/nurse. (00:28:10)
Factual error: All Arabic texts in the film suffer from wrong directional rendering. Arabic is a right-to-left language. Its letters have different joined and disjoined forms. The film, however, has rendered Arabic texts from left to right in disjoined letters. These texts aren't semantically wrong, though. For example, deciphering the Arabic message at 0:40:45 point gives "أليس "التنين فنان؟ Translation: "Isn't the Dragon an artist?" The film has even adopted a good font for them.
Continuity mistake: The coach stopped his truck along the field, parallel to Billy's Jeep but not as far up the driveway. When the coach was getting out of his truck, the truck was much closer to Billy's house, parked at an angle to Billy's Jeep, and there was a gazebo behind his truck instead of the field. When the coach was talking to Billy by his Jeep (which was also now closer to the house), the gazebo can be seen but the truck was no longer there or visible. The truck's position varied without being moved. (00:07:53 - 00:09:40)
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.
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.
Factual error: Steve Trevor tells Aquaman that he is a Colonel in the US Army. But he is wearing First Lieutenant bars on his uniform.
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)
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 changes/inconsistencies in how the lobsters were arranged on Frank's and Hildy's plates cannot be accounted for based on their movements while eating/cracking them open. (00:59:35 - 01:00:37)
Factual error: There was a lot of thunder and lightning before the lightning strike that set the barn on fire, but there was no obvious loud thunder AFTER the strike. Lightning can be seen BEFORE the sound of thunder (because lightning travels faster than sound). (00:03:25)
Other mistake: The crossbow arrow that went through Jamie's shoulder area had different positions/angles and was not always visible (in front or back) when it should have been. The crossbow arrow also did not seem to be long enough. It was not a mini crossbow arrow (3-4" where in front with maybe 5" in the back and a mini is only about 6.3" total); regular lengths are typically 14" - 20"+. (01:15:10 - 01:17:00)
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)
Revealing mistake: The "bridge" within the crime scene tape is obviously a prop. It should be a continuation of the road, but it is tilted to the left and is more vertical (around 45°). The bridge isn't even very high. When Byron and others go under the bridge to look at the dead girl, there is only a few feet above their heads (clearance under the bridge). (00:04:54)
Continuity mistake: When the terrorists take over the plane we see Eightball brutally stab a secret agent to death, and he gets blood on his face and clothing. In many scenes after this the position and amount of blood can be seen changing.
Audio problem: When Russo drives off in his Tesla, you hear the car revving and gear-shifting, despite being electric. (01:04:58)
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).
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)
Continuity mistake: When two officers go to inform Ronald Whitlock (Bruce Willis) about his sons, Ronald shoots his pistol at the Black officer and hits him near his inner right eyebrow. (A large black spot can be seen between his eyebrows.) When the camera shows the dead officer, the black mark is gone and the bullet hole is on his forehead centered about 2" above his left eye. (00:06:40)
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)
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)
