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)
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: 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: 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.
