Character mistake: When Jodie and Colt are in her trailer, discussing what should be done next, Jodie suggests Colt needs to cross the border. But they are in Australia, which only borders the sea.
Deliberate mistake: The movie reprises the mid-credits scene of Spiderman: No Way Home. However, it's a reshoot, since the delivery of the lines and the flow of the conversation are different, and so is the way Eddie returns to the SSU from the MCU. Instead of dissolving into thin air on the spot because of Strange's spell (like everyone else), here he gets violently sucked in by a portal. Also, in No Way Home, he was leaving behind a seedling of his symbiote on the counter of the MCU bar, but in this movie this happens in his own universe.
Continuity mistake: When Jack has his temperature taken near the start of the film, the thermometer in his mouth goes from right-side up to upside down, then back to right-side up between cuts.
Continuity mistake: When Samira and Eric arrive at the jazz club, Eric sits Samira down and then goes outside. A drum kit can be seen with "East Harlem Best" written on the front. Right after he leaves and right before Samira stands up to plug her iPod in, a bar stool has suddenly appeared in front of the drum kit. Eric will move this same bar stool in front of the drum kit himself again later on in the scene.
Continuity mistake: Kraven casually sniffs a couple and ruins their relationship. He then sits down with his brother; Fred Hechinger's hand keeps changing position between shots, holding a fork or not.
Continuity mistake: When Clay fights Anisette at the gas station, her heels change from stilettos to flats. Best visible when Clay throws her on a car, right after she says he should be retired.
Factual error: Secret Service Agent Miles salutes the President inside of Air Force One and has the other hand on her hip. Secret Service agents do not salute. They are not military.
Factual error: During the scene inside the submarine, you see a Commander (O5) giving orders to a captain (O6). This would never be a thing on any vessel. You would have a Commander as a Commanding Officer on a submarine, but not having a Captain working for the Commander.
Factual error: Andy crashes on an uncharted planet, and his personal assistant says the atmosphere is 2% oxygen. This is over 90% less than the oxygen concentration on Earth. When Andy comes across his crashed and burning ship (the "Borealis"), the fire is burning just as brightly as it does on Earth. The fire should be shown as burning much lower due to the small amount of oxygen.
Continuity mistake: During the "One Short Day" sequence, the Wizomania choir arrives featuring Kristin Chenoweth (on the left) singing back to back with Idina Menzel. When Kristin hits the high key, Idina suddenly disappears between instant cuts.
Continuity mistake: At the fancy dinner at the beginning of the movie, Frida uses the titular line ("Blink twice if I am in danger") on Kyle MacLachlan. Rich slightly tips over his glasses as Slater waves his hand. In the next shot, Slater is still waving, but Rich's position is wildly different; his glasses are completely off and in fact below his waistline. (00:09:20)
Continuity mistake: During the cartoon short that opens the movie, Joker, on his way to the stage, breaks the arm of a man in the corridor. In the background, slightly ahead of him in his path, is a poster for Charlie Chaplin's Modern Times. The camera angle changes as Shadow Joker turns around; he is supposed to be in the same spot, but the poster is way behind him; Joker is now standing next to the Pal Joey poster.
Continuity mistake: In the staff room of the toy store, Callum gives Jack his Monopoly box to hold. The box does a 180° spin between shots, twice.
Continuity mistake: When Anita Caprioli and Pasquale Petrolo are talking by her car, the car door hits Lillo. The two awkwardly chat for a while; during the conversation, their hands change position a few times between shots. (00:51:30)
Other mistake: Irs stabbed Richard completely through his face and shot him in the torso. Although he fell in the lake, he is later shown on the shore and he is not bleeding. Head wounds normally bleed like crazy. Since he is wounded in two places, he should have drowned or bled out from swimming to shore. (01:19:51 - 01:25:08)
Audio problem: When inside Washington D.C. and the AH-64 is firing its gun, the sound is completely wrong. In the movie, it sounds like a laser gun, and in reality, it's a M230 chain gun, which sounds different.
Plot hole: Given contestants were carefully checked for steroids at show time, mainly by urine tests, it seems unlikely Jackie would have been allowed to compete once her steroid use was discovered.
Suggested correction: Not at the amateur level, and not during the time period depicted in the movie.
Continuity mistake: When the milkman is drinking milk in the bar and talking to the Tony the Tiger actor, the amount of milk in his glass changes with the different camera angles. It goes from 2/3 full to mostly full to half full back to mostly full. (00:54:56 - 00:55:45)
Character mistake: Early in the film, Sister Paxton reveals that she wants to come back as a butterfly after she dies. Reincarnation is not a tenet of Mormonism.
Factual error: The Torre delle Milizie is visible from the courtyard in the Vatican and looks fairly close. You can't even see the tower from the Vatican. It's quite a long way away.
