Other mistake: The same shot of two guys looking at a computer while sitting outside on the school campus is used in two different scenes. (00:02:15 - 00:11:35)
Continuity mistake: When we see the first instant messaging conversation between Stone, Izzy, and Tim, Tim's screen name is "Tim86". However, when Tim starts talking to Stone, it has changed to "Tim79."
Continuity mistake: In the shot where Mattie walks towards the toilet at her school, you can see there's a pencil in her hair pointing downwards. When she's inside the toilet, the pencil's direction and her hair have both changed.
