Continuity mistake: During the scene when Kevin and Marcus (as the sisters) go to the beach, you can see that the sunlight changes during the shots. In some shots, it looks like the weather is clear and in others it looks like it's a bit cloudy. (00:55:10)
Continuity mistake: When "Tiffany" lays on the beach, you can see a magazine laying on the towels beside her. Then when it cuts to a closeup, the magazine is gone and now there is a blue shirt with a mobile laying on top and a blue and white towel has also appeared. (00:55:20)
Continuity mistake: When Kevin and Denise walk into Latrell's home, Denise has her shawl on both shoulders, but right when the lights flick on, her shoulders are suddenly uncovered. (01:07:10)

Continuity mistake: In the scene where Agent Harper and his partner bring the real Wilson sisters to the chief because they think they are the fake sisters, Agent Harper pulls down one of the girls shirts. Before the shirt is pulled down almost all of the girls hair is behind her shoulders, but when it shows her from the back all of her hair is over her shoulders. (01:29:25)
Continuity mistake: When Aubrey tells Heather and Megan that they aren't in the fashion show, Megan offers him sex for it. He lights a cigar in his mouth. When it cuts from close-up to wide shot, the cigar moves from his mouth to his hand, beside his leg. (01:33:55)
Continuity mistake: The red paint dropped on the catwalk disappears when the dragon is about to come out, but later it is back, and a lot thicker, when the chief walks out. (01:40:50 - 01:45:35)
Continuity mistake: When "Brittany" is beating up the male strippers, she is wearing tan slippers in the beginning of the fight and blue slippers at the end of it.
Continuity mistake: When the girls go into the toilet when Karen is being sick, in one shot 'The Wilsons' are holding her hair scruffily on top of her head, then in the next shot her hair is quite neat and pushed behind her shoulders.
Continuity mistake: While Marcus and Latrell are on a date, and Kevin takes the car it is dark outside. After the scene that Marcus calls Kevin to tell them they are done eating, there is a scene showing the other two agents looking through the "Wilson's" room and it is light out. The following scene is when they are all at the club, after Marcus' and Latrell's date.
Continuity mistake: When the Vandergeld sisters are on stage at the fashion show, they hear a sound and look up and see the buckets of paint. In the next shot, their heads are down as the paint hits.
Continuity mistake: When Kevin and Denise are having a glass of wine at Latrell's house, the wine glass goes from her right hand to her left hand and then she is empty-handed.
Continuity mistake: When Kevin and Marcus are talking to the other two agents, their positions change. When they are shown from the front, they are standing right next to each other. When they are shown from behind, the is a least a foot between them.
Continuity mistake: After Karen (Busy Phillips) tells off a longtime crush-turned-jerk, "Tiffany" (Marlon Wayans) comforts her. Tiffany puts (his) hands on the sides of Karen's neck and tells her a little line about "guys not seeing the beautiful thing right in front of them," or something to that effect. Watch the shots here carefully - facing Karen, Tiffany's hands are on both sides of Karen's neck. From the shot behind Karen, however, one of Tiffany's hands is on her shoulder. Both hands are back on her neck in the next shot.
Continuity mistake: Given how long it takes to air brush all exposed skin that's not a prosthetic (neck, hands, arms, etc.) it would not have been possible for Marcus and Kevin to apply their makeup in any amount of a reasonable time when their friends show up for the slumber party.
Continuity mistake: When Denise ends her broadcast at the end of the movie, the cameraman walks toward her to take her mic. The camera then changes angles and the cameraman is now instantly gone and Kevin now appears in front of her.
