Continuity mistake: At the start of the movie, in the scene where Kit and her gal pals are walking down the carpet in their prom dresses and Lucy is standing at the bottom of the stairs leaning against the banister - you will notice that behind them a little in the distance is a guy and a girl. Kit and her friends walk past Lucy and after they have gone, next shot Mimi is walking up to Lucy, as if she was walking behind Kit and her friends the whole time. You will notice that behind Mimi is that couple that were behind Kit and her friends. Where did Mimi come from? She definitely wasn't behind the girls.
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)
Other mistake: Right after Britney visited her mother, she goes into the washroom and cries. The lightswitch in the washroom is "off" and even if there was a window in the ceiling - it was raining outside. So how is it possible that there was light in the washroom above the bathtub?
Continuity mistake: When Mimi, Kit, and Lucy are looking out of the bathroom door at Ben right after Kit tells them that he killed a guy once. When you see Kit looking out of the door she has her toothbrush in her mouth. When they shut the door and you see them talking in the bathroom again she has the toothbrush in her hand and then puts it in her mouth.
Continuity mistake: 2/3 of the way through, in the scene when Kit is on the phone with her boyfriend, you see Ben and Lucy on the bed working on a song. Lucy is lying on the bed writing words down. The scene cuts from Kit on the phone to shots containing Lucy. When you see Lucy sometimes she is lying in a position with her head down on her arm and sometimes she is up on her elbows. The scenes are switching back and forth very quickly and looks funny because how the heck is the song getting written with her flopping all over like that?
