Continuity mistake: When Kayla and Stephanie are talking in the cafeteria and Kayla realises she still likes Tim, in the shot where she says "There are feelings," she has both arms extended. In the next shot, her arms are closer together and her hands are suddenly clenched. Then, in the shot after that, her hands are suddenly placed firmly on the table. (00:57:28)
Continuity mistake: When Stephanie is speaking to Emmett in the cafeteria, her position changes in nearly every shot. Depending on the shot, she is either leaning forward with both hands placed on a chair or standing upright with one hand placed on the chair and the other hand on her hip. (00:38:40)
Continuity mistake: Four girls walk into the school and make a right turn into a hallway that is perpendicular to the double-wide blue door. They walk down the hallway for some distance, past at least three long sections of 15-20 student lockers between classroom doors. After the homeroom bell rings and only two girls are standing in the hallway, they are practically back to the double-wide blue door (near the first long set of lockers). (00:18:45 - 00:19:52)
Continuity mistake: When Oliver is pushing injured Michelle in a chair down the hallway, they are approaching a long row of student lockers. When the camera shifts to a front view, they are near a stairwell and the short walls behind them are cement and brick with no lockers before the door. (00:41:05)
