Continuity mistake: When Sharkboy and Lavagirl burst into the classroom looking for Max, there is writing on the blackboard ("Science, Chapter Two") written in yellow chalk. Strangely, later in the scene the writing is now written in white chalk, and the handwriting of the text is noticeably different. Then, later it goes back to yellow! (00:16:45 - 00:17:40)
Answer: According to Taylor Lautner, the actor who played Sharkboy, he approached the role as if Sharkboy was jealous of Max because Sharkboy has a crush on Lavagirl and she pays Max lots of attention.
