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.

Trivia: When Mattie sits in the bus just before her professor tries to put himself in its path, behind her is a bearded student, an extra. Repeated views of the films will find him a total of 3 times in 3 different scenes; first in the front school yard, and then in the bus, and one more time in a computer lab.

Tim Steinberg: It has to be a virus. I mean, his computer is probably still logged on. It's just hitting his address book.
Mattie Webber: They said, "Help me."
Stone: Yeah, but viruses always have some important-sounding shit. I mean, just the other day, I got one that said, "Urgent, Stone. Read me now." I mean, that's a natural occurrence. It happens all the time.
Isabell Fuentes: That was from me, you idiot.
Stone: Damn. That was pretty strong.

Dexter McCarthy: I can still shut the system down.
Mattie Webber: Don't you get it? There's no system to shut down. They are the system.

Douglas Zieglar: The last thing you want, the last thing you ever want is for them to get to you. 'Cause when they grab ahold, they will take your will to live. Everything that made you you is gone. You don't want to talk, you don't want to move. You're a shell.
