Continuity mistake: When Eve Kim is transported into the grid, it's nighttime. At the latest, it could be a few minutes before dawn. She spends less than an hour in the grid before returning to our world with Ares, at which point it's daytime. Ares has only half an hour in the outer world before he derezzes. When Eve and Seth send him back into the grid seconds before his de-resolution, the sun is setting. Where did all that extra time go?
Factual error: Cell phones aren't allowed to be used inside the CIA headquarters building and other intelligence agencies for security reasons. One of the security guards would have stopped "Auntie" if she attempted to walk through the security turnstiles while on her phone and would have told her to end her conversation, power down her phone, and secure it in her car or in a locker outside of the building before entering. (01:35:55 - 01:36:25)
Factual error: When the movie starts, "1964" is shown on the screen. After a scary event, Lorraine goes into labour and gives birth to Judy Warren. The real Judy Warren was born in 1946, not 1964. Later, the movie moves to 1986. The movie shows a young Judy (19-20) with a boyfriend. Judy actually met and married her husband, Tony Spera, in 1979 or 1980. The movie showed them being married after 1986.
Continuity mistake: When the bus is en route to Everest, there's an aerial shot of a road with a red building on the left and a large black billboard on its roof. The bus continues for several minutes, and after the hijackers hop on, the exact same aerial shot is reused.
Factual error: Air Commodore Cyril Cooke is referred to as Sir Cyril. This is during the war, but he wasn't actually knighted until 1947.
Revealing mistake: In the "Where You Are" number, when Ingrid Luna reaches for the lamp pull chain switch, her hand doesn't actually grab onto anything. (00:43:18)
Character mistake: Heidi Heatherley is referred to and addressed more than once as Dame Heatherley. Dames (and knights) take the title before the first name, so she should be Dame Heidi. It is surprising that a journalist, in particular, would not know this.
Continuity mistake: After the female guard is lifted into the air by the witch, she falls against a bucket of yellow paint. Half of her face and her uniform are smeared with thick, bright paint. In the next shot, her uniform is noticeably cleaner and the paint on her face has faded to a light yellow tint.
Revealing mistake: When Ryan Philippe is lying in bed paralysed from the waist down talking to Doctor Rose, the camera zooms out. She is sitting on a chair, and all you can see are Ryan's legs, which he moves. (00:44:29)
Deliberate mistake: J. Daniel Atlas says the trio's abuse of his portrait constitutes a copyright violation. He's wrong. It's actually more serious. Abusing someone's portrait is impersonation and defamation. Even using it innocently constitutes a violation of the right of publicity. (00:13:02)
Factual error: It's 1946, and you can see a MiG-23 next to a fortified hangar. The plane's first flight was in 1967. (00:21:00)
Factual error: Edmond Kemper was six foot nine inches tall. When he comes home from prison at the beginning of the film, his mother is only a few inches shorter than him. That would make her huge, when instead she was much smaller than him. Likely because the actor is reported to be not much taller than average.
Continuity mistake: When the five ladies find the concession stand closed, one of them pulls out a flask. Another gets the cups from the concession stand and passes them out. They then make a toast and drink. They never poured the booze into the cups. (00:18:20)
Plot hole: At the start of the film, the club are discussing Angela Hughes' murder, and they say they need another member of the club who has a medical background to answer some of their questions on the case. That's why they eventually ask Joyce those questions. But the club actually already has a retired doctor among their number. Ibrahim mentions he's a retired psychiatrist. Having a specialism in psychiatry doesn't change the fact he's a doctor, so he has the necessary medical background.
Revealing mistake: The guy whipping her horse, Sonja throws a chain around his neck from behind and yanks him. However, you can see the actor starts to throw himself backwards before Sonja even pulls on the chain, jumping the cue.
Continuity mistake: Near the end, most of the deaths at the hands of the unicorns happen at night. Paul Rudd locks Jenna Ortega outside and it's still night. Moments later, she falls to the ground and it's afternoon. Early on in this sequence, the sun is overhead. How did it become daylight so fast?
Factual error: The film is set in Pennsylvania, but when Aunt Gladys is running through the neighborhood, she runs past a group of palm trees, which do not grow in PA. You can also see tropical, non-native shrubs in front of some of the homes.
Factual error: Anna is referred to as an MA student. At Oxford, an MA is not a qualification for which students can study; rather, Bachelors of Arts (BAs) can be promoted to the rank of Master of Arts (MA), typically upon application, after three or four years after graduation.
Character mistake: Noel says that Sam Clarke, the British Prime Minister, is the only head of state who isn't really a head of state because the King is. In fact, the British PM isn't head of state at all, but head of government. And this is common in many countries throughout the world, with a monarch or president as head of state and a prime minister as head of government. The American-style system of an executive president who is both head of state and head of government is in the minority.
Revealing mistake: When Will Zalatoris is choking his caddy, you can tell from the blue lines around the motion blur for both actors that they are standing in front of a green screen. (00:47:15)
