Continuity mistake: A guy lands on the pool table and covers up all the balls with his body. Therefore the close-up where a bunch of balls come out of nowhere and get inside the hole is senseless (well, the entire movie is, but you know what I mean).
Other mistake: Devereux and Scott are sent after the reporter to apprehend her. Only problem with that is moments before they were sent to go get her, they were naked having their injections, there wasn't enough time for them to have kitted up and gone after her with any hope of catching her.
Other mistake: Scott started juicing himself up with strength enhancers after getting his memory back. Luc only had one (that he lifted from Scott's vest during the final fight), and not even a very thick syringe either. With that one syringe, his strength equalled Scott's. How is that only one small dosage was enough to match Scott's several doses worth of strength enhancement?
Suggested correction: The enhancement isn't permanent. Scott takes them when they wear off, to get back to the "enhanced" level.
