Character mistake: David said, "Camels bite. I hear they like to bite people in the stomach. It's the leading cause of death among the Arabs." This is absurd. Generally, leading causes of death are heart disease, cancer, diabetes, high blood pressure; auto accidents may be the leading cause for certain age groups, and deaths from infectious diseases may be increasing. Resorting to statistics on the deadliest "animals", camels are not even in the top 15. Deer and bees (#14-15) cause about 100 deaths each yearly. (00:24:15)
Character mistake: Valerie approached a group of wedding attendees fighting outside the venue, saying, "Break it up" a few times. When that didn't work, she fired two "warning shots" into the air. The second shot was aimed more toward the brick porch/overhang. In general, warning shots are not permitted and it is illegal to discharge a weapon in a public place, except in the line of duty when faced with imminent threat of serious bodily injury or death. There was no justification to discharge her firearm. (00:05:20)
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)
Character mistake: Detective King (?) told Mikey, "You're on probation. You got no rights." King knew Mikey had been in prison, so should have said, "You're on parole" (not probation). Although a layperson might use probation and parole interchangeably, an employee in the criminal justice system (such as a detective) should know the differences between the terms and use the right one. A parolee is given an early, conditional release from prison and has fewer "rights" than a probationer. (00:47:10)
Character mistake: David Dastmalchian is the Polka-Dot Man, hyphenated in the comics, and in the end credits of the movie. Then again, when Waller threatens to kill everyone off, the name of the character appears in print as Polka Dot Man, no hyphen. (01:49:40)
Character mistake: The woman with the AK-47 doesn't have the covers on the red dot optic open. In other words, she can't see her target.
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)
Character mistake: Aldo tells Rodolfo to reconcile with his son, saying "Sunday is my birthday." Aldo Gucci was born on May 26th, which was not a Sunday in 1980 nor 1981, which is when the scene would take place. (00:31:30)
Character mistake: The man on the phone told Mr. Lee he wanted $960,000 cash plus $1,726,000 transferred into his account. Because the Deputy Manager was killed when the bomb in his car exploded, Mr. Lee was later told he had to pay for his share, another $1,726,000 - so he needed to transfer $3,456,000. But $1,726,000 + 1,726,000 = $3,452,000. (00:11:20 - 00:20:32)
Character mistake: Over the phone, Julie told her sister Sara, " I got them [parents] a bouquet", pronouncing the "T" in bouquet. Bouquet has French origin so the "T" is silent. Bouquet is properly pronounced like bow-kay (American English) or boo-kay (British English). (00:00:55)
