Visible crew/equipment: At the L.A. Convention Center, just before Castor Troy (as Sean Archer) disarms the bomb, there are a few shots of all the extras evacuating the area. In the interior shot, that looks out through the glass doors onto the street, the tracking crane arm with a seated camera operator and camera on its platform is visible as it shoots an exterior crane shot of all the extras, which was seen among the previous shots.
Continuity mistake: When Will Smith and the other recruits are taking their written tests, the white table first appears to be situated between the second and third men from the left. When Smith goes to the table to pull it across the room, it is much further to the right of the scene. (00:24:25 - 00:26:35)
Continuity mistake: When Leeloo jumps from the building, the elevator track, which was attached to the building on her right-hand side, has vanished. (00:30:10)
Continuity mistake: Throughout the movie, Leaven's glasses have a crack in them that appears and disappears.
Continuity mistake: Near the end of the film, when Drs. Malcom and Harding are looking for the baby T. Rex in San Diego they arrive at the new InGen Jurassic Park. The car brakes hard, skids a little pulling a trailing cable for a portable light. The lamp falls. When they get back into the car with the baby T. Rex, to use it to entice the adult back to the ship, the lamp is standing again. (01:46:52)
Continuity mistake: In the scene where Rico is first in boot camp and Dizz says she is being transferred to the unit, she gets ready to fight the drill sergeant. She drops her papers, her jacket, and her bag. It cuts away for a few seconds, then goes back to the drill sergeant and Dizz in fighting stance. The piece of paper is farther back than before, this can be overlooked because of wind, perhaps. But the jacket and bag are both gone. (00:25:55)
Continuity mistake: After Gen. Perez pushes the stacks of money towards Elgyn, they are right on the metallic edge of the table when the general offers a drink to Elgyn. In all of the following shots, the stacks have moved and are further in on the table, not on the metal anymore.
Continuity mistake: Irene's hair changes in the first scene. When arriving at Gattaca, it's a side part low hairstyle. When she's at her workstation, it's pulled straight back into a high bun. A few minutes later, when she's speaking with Vincent as they watch a rocket launch through the skylight, it's back to the initial style, a low French twist. (00:04:39 - 00:05:30)
Revealing mistake: After the toy car crashes, the group falls down a hole, but their clothes don't react to gravity, revealing the green screen trick.
