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 Kevin and Marcus dressed up as two Cuban guys pull out the briefcase full of money, they put it next to the two maracas. However, in the next shot, we see a closeup of the briefcase, and the maracas are replaced by a blue object. (00:02:30)
Continuity mistake: In the fight at the start of the movie, Marcus is thrown over the counter. Some boxes of sweets are knocked the ground, some stay on the counter. In the next shot, the counter is completely clear of any sweet boxes. (00:03:45)
Other mistake: 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 mistake: When Marcus (as Tiffany) is trying on clothes and the saleswoman helps him to get his head through the shirt hole, he is talking on the cell phone to Gina. He falls against the wall, and his wig hangs loose outside of the shirt. In the very next shot, he remembers he needs to call Gina, and his wig is completely tucked into the shirt. (00:36:25)
Other mistake: When Marcus' wife is at the restaurant, she hands her credit card to the waitress who comes back just a few seconds later to not only tell her the card was declined but to also have an agent on the phone. Given the scene is shown in realtime - there's no way all that could have been accomplished in just a few seconds.
Audio problem: When one of the "Wilsons" chases the handbag theif, she yells "You messed with the wrong blonde today," but her mouth doesn't move. (00:40:45)
Continuity mistake: In the toilet scene where Marcus in Tiffany's disguise has diarrhoea, he pulls down his panties which are pink at first. But once his legs start to move around because of the heavy farts, they suddenly turn white. (00:30:52 - 00:31:26)
Other mistake: When Marcus comes out for the first time on the runway with the real Wilson sister he's supposed to be, both of them are wearing the exact same outfits they had just walked the runway with.
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.
Factual error: When Latrell is in the car singing to one of the Wilson sisters, you can see the steam from his breath. This is supposed to be taking place on Labor Day weekend, which is the first part of September. I doubt it would be that cold at night. (01:03:25)
Continuity mistake: When Lisa is having a breakdown during the shopping trip, her hair is in a different position in every shot. (00:37:13)
Continuity mistake: When the Copelands (as the Wilsons) are shopping and Karen is helping Marcus into his clothes, Marcus says he is size 14. The shot showing the back of Karen before this shows her right pigtail hanging over both sides of her shoulder. The next shot showing her face shows it is all behind her shoulder.
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: In the beginning of the movie, when Kevin and Marcus (as the Cuban guys) are ready to give the suitcase with the money to the ice cream man, you can see that Marcus hesitates to give the suitcase to him. When Marcus is climbing up the balcony, you can see that the suitcase is gone. (00:02:30)
Factual error: When Kevin and Marcus pick up the Wilson sisters, we see them driving away on a back road by the airport. The issue is that there are no roads or surrounding areas like that in or around JFK airport where they are supposed to be.
Continuity mistake: At the "slumber party" scene where Marcus (as Tiffany) is cornrowing Karen's hair, in the first shot, only about three cornrows are complete. Then, when the camera angle comes back to them, all of her hair is completely cornrowed, which would take longer than just the two minutes it takes in the movie.
Continuity mistake: When Latrell first puts the drinks on the table in front of them, they appear to be two feet apart. However, in the next shot the drinks are only a few inches apart.
Continuity mistake: When the ice cream guy walks into the shop at the very start of the movie, he's wearing a cap, but when inside the shop, the cap is gone. (00:01:05)
Other mistake: When Kevin portrays himself as Latrell, he says he plays football; and in other scenes it's made out to sound like he's a pro-football player. But a few scenes later when the real Latrell and "Tiffany" are on their date, she refers to his basketball career as she slams his stats.
