Continuity mistake: When we first see Carlos getting up at 5am for school, he is sharing a room with his brother. Yet later in the film after he fights with his mum, he goes to bed, and suddenly he has his own room.
Continuity mistake: In the first school scene, Carlos is wearing a flannel shirt unbuttoned with large white stripes on it. After he leaves the classroom to go join Nicole and her friends, he is wearing a darker plaid shirt which is fully buttoned.
Continuity mistake: In the scene where Carlo is sitting at the table and he gets a phone call and he doesn't want to talk to them, he is wearing a blue shirt and when he walks into the hall to use the phone, he is wearing a completely different blue shirt.
Trivia: In the scene on the beach when Nicole is taking photos of Carlos, notice that when they are looking at the photo together she has red hair. That is because that scene was filmed later while filming Spiderman.
