Continuity mistake: The mole by Christian Bale's eye switches sides when he's in the oasis near the start, presumably a flipped shot.
Continuity mistake: In the first scene when Maverick enters the airbase on his motorcycle it is mid-morning based on the sun and shadows. When he takes off in the test jet it is pre-dawn.
Suggested correction: The movie sequencing/reveal is shoddy for this. Prior to him uncovering the motorcycle and heading out he slaps the calendar on the wall where it says, If I recall, "Mach 8." the day before on the calendar says something like "training" or "physical test" or something (I honestly forgot). That happens the first day ("afternoon") as shown with him on the treadmill; he sleeps on-base to get up "pre-dawn" and that's when the admiral arrives and he takes off.
This shot is likely referring to the fact that at Mach 10 he's travelling so fast towards the west that the sun (which only just set) appears to be rising again, as he outraces the darkness.
Travelling that far west would bring aircraft and pilot well over the pacific. No chance to find a lift back there.
I've watched this movie many more times since my comment. The runway assigned is "21", which has a heading of 210°, roughly southwest. This puts him facing the setting sun, but at his speed he's covering such a distance that he's actually seeing it "set" again. Even with the turn, the POV of the breakup appears still heading west. Somehow he ends up in rural (Northern?) California, walking all night to arrive at the diner for breakfast.
Continuity mistake: When Chloe, Nate, and Sully rest and talk about wine, Sully holds the glass differently between shots. One shot it's by the stem another by the foot/base.
Continuity mistake: At the wedding, Christine tells Stephen something quite hurtful; wide-eyed, he asks her how long did she have it in the barrel; a black partygoer walks behind him but is gone in the reverse shot. Moreover, she replies "Long time" and a couple walks past her, only to walk again past Stephen in the next shot.
Continuity mistake: Jack and Neytiri successfully save their children and eliminate four soldiers from a group of six. However, during the extraction scene, all six soldiers reappear.
Suggested correction: The point is, they are not just six, they are (I think 12 in total)... Lo'ak doesn't sport the second group, which is why he miscounts them as "only six."
Continuity mistake: When Daniel Radcliffe presents a special item he has put on white gloves, then a second later his gloves disappear. He no longer handles the item with gloves throughout the rest of the movie.
Continuity mistake: Towards the end of the movie, after the baseball game they go to the blue Chevy truck. One scene shows the blue truck with wheels from a Toyota Tacoma, then seconds later shows a different set of wheels on it.
Continuity mistake: In the scenes where Ellie and Grant are flying to the Biosyn facility via helicopter - all the interior shots show them flying over a solid layer of clouds. However, in all the exterior shots of their flight, there is a not a cloud in sight.
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: When the FBI realises that the Ford Bronco that Alex Lewis shot an El Paso PD officer from was full of pigeon droppings, and Det Marquez remarks that Lewis' burned-down family bakery was full of pigeons, it can be seen through the office windows that it's still daytime outside. However, when the FBI arrive at the bakery, it's late at night. It is unlikely that the FBI would take hours to show up at the bakery given how time-sensitive it was to find Lewis, or collect evidence on his whereabouts.
Continuity mistake: In Riri Williams' dorm room, the number of braids hanging over her shoulder changes frequently while Riri and Shuri are talking.
Continuity mistake: When Nick and Javi switch shoes, the camera shot on the floor shows that the shoes they have already switched are on their right feet. When they switch permanently, they both give each other a right shoe.
Continuity mistake: In the final battle, Lin Mi Sheng has her hair pinned up in a French twist. Her hair changes very frequently between shots and combat sequences. Sometimes it switches from a French twist to a slick chignon.
Continuity mistake: When Sarah fires at the jeep chasing them she brings the weapon back in with the slide in the normal position, in the next shot it is in the locked back empty position. (01:26:50)
Continuity mistake: As the "lone wolf" escapes on the bike, there's a fancy swooping camera shot which tracks him, cutting to a shot from the front just as he scythes between two dark cars and past a police car. In that quick shot a woman suddenly appears cowering by the police car who wasn't there before.
Continuity mistake: The instructions Evelyn is given had two copies created for the film - the handwriting and circling of the numbers change between shots when she's reading them in the IRS office. Notably the first time we see the instructions it says "don't forget to breath" at the bottom, then later that's changed to "breathe" as it should be. Although interestingly that change is the only one on that version of the notes, implying someone caught the grammatical error during filming and added the "E."
Continuity mistake: At the bar in Cannes, Jesse pins his pilot wings on Tom so he can make an impression with a lady. A Marine comes over, threatening Jesse. Tom comes to Jesse's defense, and he no longer has the pilot's wings on his uniform. (01:07:54 - 01:10:08)
Continuity mistake: During the "Quiet Game," the taser model changes when Rachel licks it and finishes the challenge.
Continuity mistake: Travis rearranged a photo on the desk, setting it partially in front of the box and the two pictures were a few inches apart. The next wide view showed the corner of the picture almost aligned with the box or slightly behind it and the two pictures were now almost touching. The angles and locations of the photos changed more than once. (00:09:40 - 00:10:03)
Continuity mistake: At breakfast, Robert's monitor is behind his right shoulder until Paul comes to visit and then the monitor is on the other side of the bed (behind Robert's left shoulder). (00:25:10)
