Character mistake: In the meeting in 1984 when Jason Bateman first appears they have players on the whiteboard in the background. They have "Hakeem Olajuwon." He didn't put the H back in his name until 1991. So it should have been "Akeem Olajuwon." (00:08:40)
Character mistake: When McCall put his gun to his head and pulled the trigger, he's saddened that it didn't go off. Most handguns (including the one he was using), after the last round is fired, the slide locks to the rear. He would not have made the mistake of thinking it was loaded.
Character mistake: Corinne suffers a seizure and is at the hospital with Jane at her bedside. Dr. Mitchell enters the room and, without asking what relationship Jane is to Corinne or if Corinne wants Jane to be present, proceeds to tell Corinne the results of her CT scan, referral to a neurologist, and that the hospital has a very strong oncology department. Dr. Mitchell does not take the necessary precautions to maintain Corinne's right to privacy. (00:28:16)
Character mistake: John would have no reason to ask the CT technician if she had any results. He says "that was a long one," indicating he's had this done before and should know it typically takes around 24-48 hours to get results. (Likely just a line of dialogue added for the benefit of the audience, who may not know.)
Character mistake: [Story 1: Hungry Joe] It isn't clear what blood test results the doctor receives for Joe, but Laura pleads that she "really needs to know what's wrong with her son" because "He eats, he eats, and he eats, and he never stops." The doctor dismisses Laura's concern and replies, "Growing boys eat... we'll see you in six months." The doctor should order additional tests. Blood tests can show "false negatives" and the appropriate blood tests may not have been ordered in the first place. (00:04:25 - 00:05:18)
Character mistake: Educated, intelligent, lawyer Willie Gary tells Mame, "I have this reoccurring dream... [prosecuting a case against Johnnie Cochran]." It should be "recurring dream" - keeps happening repeatedly (over and over) as opposed to just happening again. (00:51:50)
Character mistake: Co-worker Todd Pearlman tells Tracey, "Everything is going to change around here once I get the 'editor in chief' position. Hey, but don't worry. Nothing is going to change between you and I." The word "between" is a preposition and the correct prepositional phrase is "between you and me" - something a high school student should know and a basic grammar skill required for any editor or employee in a writing-related agency (publishing company). (00:14:02)
Character mistake: At the beginning of the film, while packing, Angus justifies why he has a swimsuit that looks like woman's underwear by claiming it's the swimsuit James Bond wore in 'On Her Majesty's Secret Service,' which, in the timeline of the film, had just come out a year earlier in 1969. Except, Bond doesn't wear a swimsuit in any scenes in that film, let alone a Speedo. Angus may have been boasting (lying) to deflect criticism, but he's still wrong.
Character mistake: The Captain of the USS Fragasso comes onto the bridge. A Petty Officer says, "Officer on deck," and salutes while looking out the forward windscreen. He should have said, "Captain on the bridge" and not saluted.
