Continuity mistake: At the start of the song "Chillin' Like a Villain," Evie's shoes go from having high block heels to entirely different shorter wedge heels during the song. After the song, it's back to the high block heels. (00:38:20 - 00:39:40)
Other mistake: To stop herself from bleeding after removing the tree branch from her body, Jen heats the wrapper of a beer can and places it against the wound. Later it is revealed that doing this resulted in the logo being branded onto her skin. However, if the wrapper was placed on her skin and the logo was facing towards her, then the logo should have been mirrored, but it's not. (00:57:40 - 01:05:20)
Continuity mistake: When the bald soldier gets into the cage of the apes, the amount of mud on his face changes between shots.
Plot hole: It seems highly unlikely that Lucas would be able to "mess with" Mr. Butler's application for a professorship position, or be able to accomplish what he did in such a short amount time. Off-screen, Lucas went into Mr. Butler's briefcase (foolishly left on his desk in the classroom during lunchtime) and (correctly) assumed Mr. Butler's application was on his laptop. Lucas would have to be able to figure out Mr. Butler's password (something that could take forever), find the right file on his laptop, read or scan the application to determine what he could do to mess it up, write a new answer for "qualities that make me a good teacher", and leave the classroom before anyone saw him. Lucas would also have to assume that Mr. Butler would not notice the change when he printed the application, made a photocopy, and double-checked the application before inserting it in the envelope and mailing it.
Other mistake: Lady Bird isn't finished talking about the present when the camera switches to the boy but in that shot her mouth isn't moving. Plus, right before that half her face is blocked out which sort of hides her realization face reaction. (00:17:05)
Continuity mistake: During the beginning of the family therapy session, Dr. Beckham confirms that Ellen's father is not attending and removes the empty chair from the circle, placing it by the wall. Seconds later, the chair is back (and remains for the rest of the therapy session). (00:35:05)
Factual error: The tail livery on the Concorde was not current in 1992, being first introduced in 1997. The curvy grey interior seats shown in Concorde were only introduced gradually from 1993 onwards; the film should have depicted square seating in 1992.
Continuity mistake: Gene and High Five are using costumes to hide, and Gene's costume leaves a spike in his face, but when they put the costumes down and run around the corner there is nothing on his face.
Continuity mistake: Laureline is not wearing a safety harness when talking to Valerian, but it appears and disappears several times as the shot cuts back and forth to Valerian. Laureline then puts on the safety harness she was already wearing.
Factual error: In a picture from the UN headquarters in New York in the year 2003 you see two German flags. The German Democrativ Republic hasn't existed since 1990. (01:16:04)
Factual error: When Mark Felt and the FBI Director are in a car on the way to the Watergate hearings in 1972 or 1973, from the car window, you see the WW2 memorial, which was built in 2004.
Continuity mistake: When Mae and Ty meet, when Ty asks what does she think of this, Ty begins removing the lid from the bottle of wine he is holding, but in the next shot, the lid has suddenly been removed from the bottle, with his hand nowhere near it. (00:21:25)
Factual error: Throughout the whole movie, whenever federal agents (or people posing as such...) tasked with the case are shown, they wear uniforms with "U.S.A. Marshals" written in big yellow letters. Of course the one and only correct spelling would be "U.S. Marshal"
Continuity mistake: During the drunken gymnastics young Miss Langford is doing to the delight of the paparazzi, she is wearing transparent pantyhose for the most part of the scene; you can see it during the cartwheels with the panty shot, and with the feet close-up. However her legs and feet are bare when the camera shows a stuntwoman leaping over the gifts and crashing into the tree (probably they didn't want to tear the stockings with that landing). (00:02:30 - 00:03:55)
Continuity mistake: During the opening scene with Ego and Quill's mother, they run into the woods behind the Dairy Queen, and mom is wearing boots with fur trim. When they get to where the Ego's plant is in the ground, she is suddenly wearing sandals.
Factual error: The American flag displayed when Churchill arrives at the big house to meet Eisenhower has a modern day configuration of 50 stars, not 48 as it was at the time.
Other mistake: Where did those spikes above and below the rear door come from? They exceed the height of the door.
Audio problem: When Rob starts accusing Benny of knowing what happened to him the previous night, Benny says that they just hung out and Rob says "Shut yo ass up" to Benny. The shot is focusing on Benny, with the camera behind Rob and his jaw does not move when he is saying the line. (00:56:20)
Other mistake: When Rodrick and Greg bought groceries, there was one bag of "Cheez Curlz" and it ended up in the hot tub at the motel. They weren't shown buying another bag yet they had one when the pigeons "attacked."
Continuity mistake: On the third and fourth day, Carter's roommate shows up earlier than the first 2 days. And Tree's suspect tips notebook every day don't reset and the line and erases are the same.
