Revealing mistake: While Wayne, Diane, Patty, and Gordon are in the laundry basket, Adam and Mitch carry that basket upstairs. When Mitch says, "I bet my parents wish I didn't have a medical problem," the camera turns to follow the boys as they walk up the stairs, and the left wall (with striped wallpaper) of the staircase is missing to accommodate the camera filming from that angle. It's visible again when Mitch says, "And I feel fine." (00:35:35)
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)
Visible crew/equipment: When Nisi and Mickey first walk into the bathroom Mickey asks why there are two toilets, and in the next shot the microphone pops up into view at the bottom of the screen.

Revealing mistake: During the honeymoon sequence at the end of the film, if you look at the right top of the flowers in the vase during the "flowers covering nipples" bit, you can see a bit of red duct tape covering Liz Hurley's nipple from behind the flowers. (01:22:20)
Visible crew/equipment: At the beginning of the movie when Clark is entering his house and the camera angle is from inside, just as he opens the door there is something red on his front porch. If you look at any of the previous scenes, that red thing isn't there. It's the bottom of a sunscreen being used to block the bright sunlight (which would have flooded the camera) behind Clark as he enters the house. (00:01:44)
Continuity mistake: During the hockey fight, number 12's helmet is off, then on, then off again. (01:17:00)

Continuity mistake: Simon has a rack of pool balls on his coffee table. When Melvin is telling Simon about the bacon, the 2 ball (solid blue) is near the telephone. In the next shot, the dog jumps up to get the bacon and now the 3 ball (solid red) is near the phone. (01:01:20)
Continuity mistake: When Celine is tied up playing blackjack, the position of the rope holding her varies. We see for example that the number of times the rope crosses her chest goes from three to four and back again.

Continuity mistake: In the beginning when a talking burger comes out of the bag, sauce packs in the tray at the bottom right change between shots.
Continuity mistake: When Giosuè is hiding in the small cupboard Guido puts some flowers on top and some of the blossoms hang over the edge. In the next shot they are all lying on the cupboard, but when the camera angle changes they are hanging over again. (01:01:45)
Continuity mistake: When Bill Murray is talking to the dead guy in the chair, the dead guy's eyes are open. But from a side shot, they are closed. (00:33:00)

Continuity mistake: At the end, just after they finish singing, and are all posing, Posh and Ginger's poses change with every camera angle.
Continuity mistake: When Weebo creates a holographic human version of herself on the computer, the sticky notes on the computer constantly disappear, reappear, differ, or change position throughout the scene. (00:41:12)
