Other: At the beginning of the film, The Real Wilson sisters are portrayed as being vindictive, stuck up and spiteful. But at the end of the film, their personas have changed to typical "dumb blondes."

Continuity: 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.

Continuity: 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.

Revealing: When Marcus (dressed up like one of the sisters) is braiding the blonde girl'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 were the wig starts. Also it's probably a wig because when Marcus (dressed up like one of the sisters) is braiding the hair he just looks like he is moving it and that the braids are already done.

Continuity: When the "Wilson sisters" and their friends are driving along, the "Wilsons" start singing "Nigga" along to a song, and between a wideshot and closeup the background goes from being all trees in the distance, to suddenly all the sunny sky showing, and trees appearing/disappearing/changing. The background changes a few times when the girls sing to the Vanessa Carlton song too.

Audio problem: When Kevin, as Tiffany, 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.

Continuity: 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.

Other: When the two rival agents 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.

Continuity: 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: 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 disappeared for the stunt.

Deliberate "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.

Continuity: 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: 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.

Revealing: When one of the 'Wilson' sisters leaves with Latrell for their date (after he starts singing to her), the car they get into is supposed to be valet delivered just before they step into it, yet when it pulls away there is a visible dry spot on the road beneath it. Clearly the car had been parked on that spot for long enough that the heat from the engine dried the wet pavement underneath it, which would take far longer than the length of one song.

Other: 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.

Other: 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.

Continuity: 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.

Plot hole: Kevin and Marcus's plan is flawed because, if Kevin had to "valet" park the car and he used it to drive Denise to the house he would have to: drop her off, return the car as Kevin, and somehow change into the girl disguise on. Unless he dropped off the car with the girl disguise on, it would be impossible to do that unless he brought a bag with him. Also he would have to somehow travel to the club and get there before Marcus.

Continuity: 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.

Continuity: At the disco, Latrell puts drugs into Tiffany's drink. Tiffany finds out and switches the drinks around. When she did this, the "drug" drink was still in front of her. In the next shot, it is in front of Latrell.
