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: As the hand creature busts the shackles off Boris' legs in Lunar Max, you can see the bottoms of his pants over his metal prison boots. There are only a few folds and wrinkles over his left foot, and the pants over right foot are hardly wrinkled at all, or affected as the creature climbs up his right leg. But only a couple of seconds later, we see another shot of Boris' feet as the creature breaks off the metal sleeve of his arm, and suddenly his pants legs are very wrinkled. Boris was standing perfectly still the entire time. Boris' legs are also suddenly closer together. (00:03:35)
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 surrounded by police and a garbage truck, Frank drives his car from the overpass onto the passing transport trailer below, then lands behind a hatchback and in front of two cars - a white compact with a sunroof and a grey hatchback. In one specific shot from atop the trailer, as Frank rolls his window down (before he requests the gun) the only vehicle behind Frank's car is the white compact, which is at the trailer's rear. Note things such as the trailer's safety bars, and the view through the compact's windshield for starters. That grey hatchback is back when the ramp is lowered, for the ensuing crashes. (00:08:20)
Continuity mistake: When Marty chases after Biff on the borrowed 'skateboard', Marty is wearing a dark grey belt and a red/blue print shirt under his red/beige jacket. However, when Marty is hanging on to the front of Biff's car as they turn a corner (and in another shot), Marty (stunt double) is wearing a light brown belt and solid tan shirt. (01:07:00)
Continuity mistake: In the library scene Indy discovers the "X" high up on the balcony. The X is green with a grey background. When he breaks the tile to find the tomb the X has become a faint outline on the floor. (00:27:40 - 00:28:45)
Suggested correction: You still can see one "leg" of the X on the floor, it's only darker than viewed from above because the camera angle and illumination set used.
I think it is meant to be an optical illusion.
The "X" is first shown as a dark green "X" on a beige background. Next, we are shown the same dark green "X" that is barely visible over a green background. I think we are meant to understand that the beige square tiles were lifted away in a cut scene.
I see no reason why they would replace the floor just for the higher shot, it's the same floor throughout the scene. When they enter it's the same floor we see later as they are going into the hole. It's probably not a real marble floor, so they can use a styrofoam or plywood tile that Harrison can lift, one that matches the surrounding tiles. They don't shine as much as the rest of the floor. In the shot up high there is different lighting, so that could explain it. It just appears to be different. Of course, sudden different light can be seen as a revealing mistake.
Suggested correction: Not a mistake, just a different viewing angle.
Continuity mistake: In the beginning scenes, where Milo Thatch is practising his proposal, he slides over (face forward, chest against the board) a chalk drawing of a map detailing the location of Atlantis. When he realises he wiped off the drawing, and sees it on his clothes, he stands in front of the blank part of the chalkboard, "filling in" the space with the map that rubbed off on his shirt - the only problem is, that the image should have rubbed off backwards as he was facing the board when it transferred to his clothes. He could not simply stand in the place of the missing map face forward and have it read properly.
Continuity mistake: When Magneto lands the Golden Gate Bridge on the island, as it hits land it is still very light. When the Brotherhood start to walk toward the island, it cuts to a wide shot of them still walking on the bridge, and it's suddenly dark.
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 General Grey tells the President not to engage until they have visual, in the President's close-up the exterior of this F/A-18 Hornet is quite different than what was shown in the earlier shot, as the canopy closed over him. All the rivets around the canopy have disappeared and the 'danger' triangle is much closer to the name Patrick, the seat differs, etc. Plus the fact that the canopy and hull are actually one unit in the second shot. (02:02:15 - 02:03:15)
Continuity mistake: When Karl Urban is defending the Asgardians, the dust covers on his rifles vary between being open and closed several times. M16 dust covers are sprung loaded - they open on the first shot and have to be manually closed afterwards.
Continuity mistake: Cross is holding a normal striker fired (no external hammer) Glock handgun against the head of Ant-Man. In order to save his life, Hope orders the ants to block the firing mechanism of the gun, and they block a suddenly-visible hammer on the Glock. (01:26:00 - 01:27:00)
Continuity mistake: When Mrs. Otterton is in Chief Bogo's office holding her family photo with both paws, in the wideshots her purse is hanging in the crook of her left arm, but after a brief shot of Judy, when it cuts to Mrs. Otterton's closeup as she tells Bogo about her two beautiful children her purse is gone, then after another brief shot of Judy the purse is back in its place again in the wideshot.
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: After being chased by soldiers after talking to his uncle, Dastan gets into a swordfight with Garsiv. As soon as it starts, Garsiv hits a pillar with his weapon knocking a significantly large chunk and a another smaller chunk out of it. In the immediate shot, the size and locations of the two chunks differ.
Continuity mistake: When Padmé gets her back scratched by the nexu, she seems to bleed. Even though she is wearing all white, and the scratches seems to be deep, her white top remains squeaky clean during the rest of the movie and does not get dirty from her wound. The wound itself also vanishes, not reappearing for the rest of the Geonosis sequence, even when she falls out of a gunship and goes rolling in the sand. (01:47:35)
Continuity mistake: When the two female characters enter the fancy hotel room, they make a point to say they will only be there for a couple of minutes. It is daylight when they go in. The visit is cut short (the one that's supposed to be a few minutes long) because of a gun battle in which one of the women dies and the other escapes. The escaped one gets out through the roof into an evening's sky. There's still light visible, but for a visit that lasts all of 4 minutes, it's far too quick a change. (00:23:00)
Continuity mistake: When Johnny Cage is fighting Scorpion, and he does his human spear, Johnny runs until he stops at the tree. The spear then catches up, and becomes wrapped around the tree in front of Johnny. When the camera changes view, the spear is just leaning on the tree. The camera changes view again and the spear is wrapped around the tree again. When Scorpion pulls the spear back, it goes straight back, and doesn't unwind around the tree.
Continuity mistake: When Daredevil kicks Bullseye off his motorcycle, Bullseye has nothing in his hands when he's flying through the air, but when he lands he's holding Daredevil's baton. Watch closely when Daredevil's kick connects, and you can see they never even come close enough for Bullseye to grab the baton, or for him to snatch it if it was dropped. (00:59:40)
Continuity mistake: During the chase scene on the bridge involving the tank, two cars (silver Toyota Corolla hatchback, licence NE34 12 and a black VW Bora, licence NU67 67) appear during many shots, often travelling in different directions on the bridge and either ahead or behind the chase.
