Other mistake: Near the end, when Julie is pushed off the building by the henchmen, her handcuffs get caught on some rods that where sticking out. But this is impossible, by the way she was falling (vertically) the rods would have made contact between her legs. No way her handcuffs could have been caught like that. And they were sticking out a good foot or two from where her body was.
Continuity mistake: When Peyton returns to his lab after its destruction, a burnt picture of him and Julie is on the floor. The destroyed picture shows half of Peyton's face missing. After finding a new place to stay, when the picture is put into the scanner, more of Peyton's face is visible.
