Other mistake: When Marcus and Kevin reveal their real identities to the crowd, their eye colour changes from blue to brown without any indication that they removed their contact lenses. They simply lift off their masks. (01:38:10)
Continuity mistake: In the first scene with Marcus and Kevin dressed up as women, they walk to the hotel counter and knock things off the rack. Depending on the camera angle, the things spilled on the counter such as the cup, pencils and pens disappear, reappear and change position. (00:21:20)
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: After Kevin and Marcus knock down the ice cream guys, they take off their fake chest hair and put it down. After a few shots, the hair is back on their chests, but a few shots later, it's off again. (00:04:25)
Continuity mistake: When Marcus and Kevin, as the Wilson sisters, arrive at the Royal Hampton Hotel, when they exit the limo Kevin's breasts are a normal size, but when they walk into the hotel and he knocks down the stuff on the counter, his breasts are huge. (00:19:25 - 00:21:00)
Continuity mistake: When the "Wilson sisters" and their friends are driving along during the music scene, between a wideshot and closeup the background goes from being all trees in the distance, to suddenly all the sunny sky showing, and trees changing and appearing from shot to shot. (00:33:45)
Revealing mistake: When Marcus (dressed up as Tiffany) is braiding Karen's hair, you can easily tell that the corn-rows were already done, and that the hair that is not done is a wig. You can see the line where the wig starts. Also, it's probably a wig because when Marcus (as Tiffany) is braiding the hair, he just looks like he is moving it, and that the braids are already done. (00:49:25)
Other mistake: When Gomez and Harper find Marcus and Kevin's masks, the masks are shown with lips attached. Whenever we see shots of the guys putting on the masks, there aren't any lips attached; they put their own lips through a hole. (01:15:00)
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: 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.
Audio problem: When Kevin, as Brittany, is in the hotel lobby she starts to write a letter she says "Dear Mister Royal Hampton." then it cuts to a behind shot and she says "I am a white woman in America." but his jaw doesn't move.
Plot hole: Kevin and Marcus are supposed to be bringing Brittany and Tiffany to the hotel in the Hamptons. But they get into a car crash on the way and have to stop somewhere else. When at the stop, they tell the girls to stay in the hotel and they become the girls. The problem, when they get to the hotel dressed as the girls, the two men (Marcus and Kevin) are supposed to do the hand off to the FBI agents at the hotel. But they aren't even there because they are dressed up as the girls. How does the FBI go the entire movie without once contacting them and especially, how do the FBI agents accept the girls without the correct handoff from Kevin and Marcus?
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 Brittany fights with the strippers, in the background there is a table with a blue plate, a phone and a lamp on it. But when Brittany throws one stripper into the table, the lamp has been moved to the floor for the stunt. (00:52:00)
Continuity mistake: When Kevin and Marcus are driving Brittany and Tiffany Wilson to their hotel, Marcus, who is in the back, emerges from all the bags in the backseat. Between shots, the bags around him constantly move, and in the first shots, a brown bag jumps from behind him to under his arm. (00:13:15)
Other mistake: In the scene where Marcus and Kevin are first dressed up as the Wilson sisters, as they step out of the limo, Kevin (as Brittany) tells Marcus (as Tiffany) to act like a normal girl. Then Marcus flips his hair and the part in his hair is now crooked because he didn't get all of his hair back to one side. The next time you see him, the part in his hair is straight, and his hair is no longer out of place on top of his head. (00:19:55)
Continuity mistake: When the ice cream delivery men pull up to the bodega, they park directly in front of the newspaper dispenser. When we see a shot of them walking into the store, the newspaper dispenser is shown but the truck is nowhere in sight. (00:01:10)
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.
