Continuity mistake: The Saturn that Mikaela is driving has a moonroof that encompasses most of the roof, over the front and back seats. When the Decepticon Grindor captures them, in the interior shot looking up at Leo as Grindor seizes the Saturn, the car has a solid roof over Leo, which is also seen in the interior shot as they fall. (00:54:05 - 00:55:05)
Continuity mistake: In the scene where Jake wakes up from his link and Grace asks him, "Is the avatar safe?" and he replies, "Yeah Doc, and you are not gonna believe where I am," her hand is on top of his shoulder. But as the camera angle changes back and forth her hand switches to the side of his upper arm and back to the shoulder without time to have made the move. (00:48:55)
Continuity mistake: During the prison fight scene, Silk Spectre's stiletto boot heels are alternatively flat-soled from shot to shot, for the stunt woman's benefit.
Continuity mistake: Right after Marcus gets the Jeep to start, they begin running from the Aerostat. They start off going down a steep hill and the windshield is practically sparkling clean. Once they get to the road at the bottom, the shot shows the windshield caked with mud. (00:34:00)
Continuity mistake: Gambit pushes Logan, who smashes through a wall. This hole becomes much, much smaller when Gambit climbs out into the alley. (01:10:00)
Visible crew/equipment: When Chun-Li and her family arrive at their new home at Hong Kong, as the old servant opens the door, the reflection of the boom mic is visible on the black door. (00:01:55)
Visible crew/equipment: In one shot at the end, when all the surrogates fall to the ground, you can see a few crew members (one with a white megaphone) standing in the street in the upper left corner. (01:19:55)
Continuity mistake: In the scene on top of the drill, Kirk falls off the edge. When Sulu helps him up, he's holding onto the platform with his right hand and being helped up by his left, but in one shot he's holding on with his left hand, and being lifted up by his right. (00:57:25)
Continuity mistake: When Henry is telling Claire about his vasectomy, the paper mold on the table in front of her is right-side-up in one shot, then upside down, and then back to right-side-up.
Continuity mistake: In the desert, throughout the chase scene between the black SUVs and the taxi, the damage on the front bumper constantly changes. It 'fixes' itself several times, most notably on the left side. (00:15:00)
Continuity mistake: At the very beginning, as Ana is running away with the Nano warheads with Duke following, she is first holding the case in her right hand. Cut to a shot in front of her and the case is now in her left hand. It is back in her right hand in the next shot. (00:12:10)
Continuity mistake: When Jackson and the kids are at the dried up lake in Yellowstone park, they walk past the carcass of an elk. We change to the long shot, and when the army arrives, the carcass has gone. (00:21:35 - 00:22:05)
Continuity mistake: When Bulma and Goku have just finished fighting and begun talking; watch Bulmas' blue streak of hair. It's on the left side of her head throughout the conversation until goku says "you might need back up." The camera shows a close up of them shaking hands, and when it cuts back to Bulma, the blue streak is on the right side of her face. There is no indication of her moving it, and there's not enough wind to blow it to the other side. (00:26:25)
Other mistake: When 1 strikes off 2 (I think) from the calendar we can see that 1 is Wednesday, 2 is Thursday, 3 is Friday and that 4 is Saturday but 5 is Monday; meaning that Sunday has no date.
Continuity mistake: The private who was being injected with the blood substitute explodes, splattering red goo all over the glass panel. The amount increases in shots from outside the room, covering the entire panel. (00:14:45)
