Factual error: When Lucy walks out her teacher says "Lucy," and her sash thing is blowing in the air, but in the next shot of Britney it is perfectly still. (00:02:12)
Continuity mistake: In the scene where Lucy, Mimi, and Kit are digging up the box they had buried earlier in the movie, look at the first thing that they pull out. It is a Barbie that belonged to Kit with nothing under it. Soon you will see a locket, key chain with a globe on it, folded piece of paper, and a picture. Where did those items from, there was certainly no space left in the area. (00:08:00)
Factual error: In the bathroom scene at the motel where Lucy is in the shower and Mimi is using the toilet, Mimi flushes the toilet and Lucy yells "Ahh, freakin' cold," however, if someone flushes a toilet whilst another person is in the shower then this would result in the cold water being removed from the shower, so Lucy really should have yelled "freakin' hot," unless the toilet water was hot water. (00:23:35)
Continuity mistake: Throughout the scene when the three girls are in the bathroom, Mimi has a pink toothbrush that keeps disappearing and reappearing from behind her ear. (00:23:40)
Visible crew/equipment: When Lucy is telling Mimi off for not actually KNOWING Ben, or telling them he was an alleged murderer, Lucy's towel slips and you can see the top of a pale beige bodysuit. (00:24:20)
Continuity mistake: When the car was broken down and the girls are about to fight, Britney is on top of the car about to get off. If you look closely at her, she gets off the car two times. (00:30:20)
Visible crew/equipment: When the girls are singing "I Love Rock N Roll" at the karaoke bar they always scan back to Ben sitting at the bar. One of the times they scan back to Ben, you can see the camera man in between a girl sitting on top of the bar next to Ben and a girl sitting on a stool. This happens in between those 2 girls who are sitting to the left of Ben. It goes by really fast so you might have to pause it. (00:37:10)
Continuity mistake: When they are singing "I Love Rock N Roll" at the end of the song Britney is standing in the middle of the stage with the girls behind, then she is on the platform with the poll, and she keeps going back and forth. (00:37:15)
Continuity mistake: When Ben changes his shirt, Lucy's locket disappears and then reappears. (00:44:55)
Continuity mistake: While at the hotel in LA and Kit is talking on the phone, Mimi can be seen in the background unpacking her bag. A one point Mimi walks on camera, looks in and around the stuff on the bed then turns to someone off camera and shrugs and by her mouth you can tell she is saying "Where?". Whoever she is talking to is not another character, as all the others can also be seen behind her. (01:09:05)
Continuity mistake: Toward the beginning of their drive, while the girls are singing "Bye, Bye, Bye" the position of the window behind Mimi keeps changing. Sometimes it is all the way up, then it is part-way down, then back up again.
Other mistake: When Mimi is in hospital Lucy stands at the door and Mimi has a tube in her arm. Then when Lucy goes over to the bed the tube has disappeared. Then later it appears again.
Continuity mistake: When Lucy, Kit, and Mimi are singing "I love rock 'n' roll" Lucy has glitter eye shadow on, but when the get to the motel that same night, she has on blue eye shadow.
Continuity mistake: When Ben, Mimi, Kit and Lucy are in the waffle house talking, you see Ben is eating a sandwich, in some shots he is holding the sandwich, then it is on the plate, then he is holding it again.
Continuity mistake: After the first motel stop, Lucy and Ben are talking and the camera pans back and forth between the two. Each time it hits Lucy her purse straps have magically repositioned themselves on her shoulder, without her help.
Continuity mistake: In the scene where they first start traveling towards California, you can see that in one shot Ben's car has a rearview mirror, but in the next shot there is no rearview mirror. It goes back and forth like that several times before they go to the diner to count their money supply.
Continuity mistake: In the car when Ben is telling the girls about why he was in prison you can see that Kit is braiding Mimi's hair but in the next scene when Britney is debating on whether she's going to call her mother to give her notice, Mimi's hair no longer has the braids in them. When they are dropping Lucy off at her mothers house the braids are back in again.
Audio problem: When the girls are digging up the box, Lucy says, "Me either" as she is bending down, but if you look closely her lips are not moving.
Continuity mistake: When the car pulls up to a hotel in Alabama, the sign underneath the hotel name reads "vacancy". When they show Ben and Lucy talking outside, the sign has changed to "no vacancy". In the next shot, it is back to "vacancy".
Continuity mistake: Britney's nails keep changing throughout the movie.
