Continuity mistake: In the scene where Ashley says that they've got CDs in the tanning salon you can see Ashlyn keeping a cream tube on the table with her right hand. In the next shot you see her continuing the same action with the left hand.
Continuity mistake: In the scene where Kevin and Wendy are talking outside of the school, Kevin's hair change positions depending on the shot. At the same time, each time the shot goes back to Kevin, not only does his hair change, but the people behind him. It switches from Julie and Perry to random people, then back again.
Continuity mistake: At the end of the scene where Ashley and Ashlyn are burning in the tan beds, one of them looks out of the side of their tan bed. This is supposed to be Ashlyn, but she's facing the wrong way, which means she would have to be in the tanning bed she didn't get into to make this shot right.
Continuity mistake: During the scene when Wendy is looking at her camera and Julie walks in to ask if its ready yet, you can see Wendy holding the paper with Ashley's number on it. Then when Julie walks out, Wendy turns and sees the paper on her desk, no where near her hand.
Continuity mistake: During Frankie's death, right after the shot of Wendy and Kevin escaping, there is a very quick shot where Frankie is not in his car.
