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 the cow blows by the truck, the truck is driving down an empty dirt road with water on both sides. During the shots of the occupants, the road behind the truck is paved and dry. Also in one of these rear shots a truck (Red Chevrolet Blazer) drives by in the opposite direction. (00:42:25)
Continuity mistake: When Joker is dancing on the stairs he throws his cigarette. Then when the cops arrive at the top of the stairs we see him blowing smoke from the same cigarette. Then the cigarette is gone again. (01:30:40)
Suggested correction: They purposely stuck the images in a way that it repeats itself over and over again. It's intentionally made in a way of not flowing straightforward.
Continuity mistake: Toward the end, Russell goes to talk to William at his house. He turns the chair around to sit on it backwards, and throws the shirt down onto the ground. When he sits down the shirt is back on the chair.
Continuity mistake: When the Stukas are shown bombing the beach, they drop a single bomb, but from beach level, you see sticks of bombs landing.
Suggested correction: The Stukas are dropping SD-2 canister bombs, a particularly nasty anti-personnel weapon. Upon release from the aircraft the bomb divided into the bomblets you see here.
First known use was bombing of England, no evidence they were used at Dunkirk. Also, the SD-2 was smaller and produced numerous small explosions. The ones we see in Dunkirk are larger and much bigger than anything the little SD-2 could ever produce - so the original criticism sticks.
Continuity mistake: When the police are moving in to arrest Dzhokhar Tsarnaev, the shot shows an FBI SWAT officer grabbing him. But in the next cut, the officer changes to a Boston Police Officer while changing back to a FBI Officer in the following shot.
Continuity mistake: When Fox and Wesley first jump off the building onto the moving train, Fox has on boots with heels, but when she lands on the top of the train, her boots are flats.
Continuity mistake: The morning after Vivian's first night at the hotel, room service brings breakfast. When she's eating a croissant it cuts to a shot of Edward, and when it cuts back to Vivian she's eating a pancake which goes from being half done, to being a whole pancake again. (00:30:55)
Continuity mistake: When Eliot Ness is at Jim Malone's house for the first time, Malone's collar is opened, then buttoned, then open again.
Continuity mistake: Towards the end, Denzel drives his car into 2 cars trying to get Ethan off the hood. After that scene ends you see Denzel driving the same car and the front and rear of the car look nothing like they did when he was crashing into the cars.
Continuity mistake: During the scenes at her Mother's house, Kate's hair goes from blonde to REALLY blonde.
Continuity mistake: In the aircraft scenes after the blast in Baltimore, watch the clocks closely. The times go forward, backward, and everything in between.
Continuity mistake: When Hal's co-workers bring him a cake for his promotion, Rosemary takes a slice out for herself. They change shots a couple times, and the size of the piece missing from the cake changes several times, and the layers of the cake change as well.
Continuity mistake: When Bullock is warning Reeves of the coming winter blizzard, she is looking through pictures that depicted her and her friends enjoying the snow. She then turns to the dog and asks "Remember that day? You were not happy". However it's revealed that both characters have the same dog, given to Bullock's boyfriend by Reeves, so when the snow happened in Reeves' time - 2004 - the dog was with him.
Continuity mistake: When the main character goes to visit his friend that had been shot in Iraq, they're driving down a country road in a 2 door Dodge Challenger, but when inside the vehicle it's a Dodge Charger, which is a four door car.
Continuity mistake: When Norma and Helen are in the salon, and they are talking about Carrie going to the prom with Tommy, Norma is getting a fancy hairdo done for the prom. But in the next gym scene, she has her plain braids and a cap on. (00:48:20)
Suggested correction: When you watch the movie leading up to that event, it's obvious that Norma is a tomboy, and is always wearing a ball cap and wearing her hair like that. It's who she is and perhaps decided after her hair was done that it didn't feel right and decided to go back to her look.
Continuity mistake: When "Charlie" is first introduced to the class, she struts down the aisle in heels. When she follows Maverick into the building, you can briefly see that she is wearing flats to compensate for Maverick's short stature. (00:26:00 - 00:28:50)
Continuity mistake: In one of the last scenes, Cate Blanchett is standing in the doorway of her son's room. She is wearing a blue striped dress. When she walks into the room, she's wearing a floral dress.
Continuity mistake: There is a scene where everyone is dancing. It's towards the end but not at the very end. One of the employees of the record store takes his shirt off. Then the camera cuts back and you see the entire group of people dancing. If you look at him he has his shirt back on. Then a couple of shots later he has it back off again.
Continuity mistake: At the beginning Ava shoots the man's phone out of his hand through the car window. When the car drives away all the windows are intact.
