Factual error: The radar guided SAMs are consistently evaded/triggered by the pilots' flares, which in reality only work against heat seeking missiles. Radar guided missiles would be defended against using chaff, basically clouds of aluminium foil strips. It was mentioned in some interviews they didn't want use chaff as it wouldn't really be visible for the audience - hence why they only deploy flares.
Other mistake: Among the credits for the film's music are "principle first violin" and "principle second violin." The correct word is "principal."
Other mistake: When Batman is video calling the Riddler and passes the phone over to the D/A, you can see Batman's face still looking at the phone in the reflection of the Riddler's glasses.
Plot hole: Vulture was able to re-create his suit despite the tech for it being confiscated when he was arrested. Also, the tech does not exist in the Venomverse, so he would have had no means of accessing it by any stretch of the imagination.
Factual error: The pub sign states "whisky" - Irish whiskey is always spelled with an E.
Continuity mistake: Marion's shoes change when in the museum, from heels to flats.
Continuity mistake: The first time we see the scene of Birdie sitting poolside waxing about her and Miles' fame, she brings her left hand up to hold down the side of her large hat, which obscures the camera from seeing Ms. Brand sitting down next to her, and when done speaking she pulls the hat down from the brim. When the scene is shown later a second time from Brand's point of view, when Birdie is talking she isn't holding the side of her hat, and takes it off from the top.
Factual error: On July 4, Kya waits for Tate, watching the sun set and the fireworks at night. She falls asleep on the shore and wakes up in the same position, watching the sun rise. So the sun sets and rises in the same position. (00:55:40)
Continuity mistake: When Priscilla meets Elvis in Germany the position of the letters on the bed and of the papers scattered on the floor change positions between shots.
Other mistake: When Captain Collins climbs out of the water after falling in, her tank top is completely dry. (01:22:00)
Continuity mistake: At the end, the French soldier tries to kill Paul in the wet mud. When they finish struggling and spot the pistol on the floor, the mud on Paul's face is now dried and caked on.
Continuity mistake: At the pleasure island before Lampwick gets into the wheel of fortune, he has his glass full of beer, then it is empty, then full again.
Continuity mistake: When the moderator tells Lydia "I couldn't help but notice you flinch just a little bit", Lydia has her right hand placed firmly on an armrest. When the shot cuts, her right hand is away from the arm rest. (00:09:15)
Continuity mistake: In Riri Williams' dorm room, the number of braids hanging over her shoulder changes frequently while Riri and Shuri are talking.
Character mistake: While discussing his squad providing air support for the Marines on the ground, Lt. Cmdr. Cevoli refers to the men as "soldiers." Marines are not called "soldiers" because they are not in the Army. It is common for a layperson to make this error but nobody in the U.S. Navy would do this.
Factual error: A .22 shot would be 120-140 dB, muffled with a pillow down to 100-120 dB. Only one person heard the second shot? No one heard the third? Plus at the end there's no way a .22 could pass through a male chest cavity, and halfway into a female chest cavity - it's too low power.
Character mistake: After Dimitri put Leena's wrist bands on for her (through the door slot), Leena said, "I want to do something nice for you; you can come in." Dimitri agreed, and Leena pulled up a chair to stand on (to be his height) and caress his face/ hair. When Leena bent in to kiss him, she banged his head against the wall several times, killing him. As a "Saarne Instituute" security member, Dimitri should know not to get sexually involved with or trust a patient, especially the most dangerous one. (00:10:29 - 00:11:29)
Suggested correction: And yet this very thing happens in real life. There are several cases of guards getting manipulated sexually, manipulated in general, or even killed by dangerous prisoners or mental patients. A part of this has to do with some guards getting in the business believing these people are misunderstood and that they can change them. As it happens in real life, there's no reason it can't happen in a movie. Movie characters aren't above real life mistakes.
Factual error: One of the warriors tells a trainee they move like a sloth, more than once. Sloths are only found in the "new world", not native to Africa.
Continuity mistake: Simi enters the bedroom and the upper half of the bedspread is smooth. Aunt Claudia is holding a book with both hands, so she is not touching the bed. The front (somewhat aerial) view of the bed shows that the upper part of the bedspread has multiple ripples. (00:17:55 - 00:18:42)
Continuity mistake: Gilbert/Robert was wearing a red pocket square (left lapel) when he was in the phone booth, but not when he came out of the hotel. (00:03:38 - 00:04:36)
