When the FBI agent handcuffs Madeline, her bracelet is below the handcuff. When she is lead away the bracelet is further up her arm above the handcuff.
Aerial shots of Management's helicopter as it flew into Miami were of a Eurocopter EC130 but the shots where the helicopter landed on the helipad were of a Eurocopter AS350.
When Madeline is asked where she was supposed to meet Mike, she gives the Sawgrass Mills food court as the location. Sawgrass Mills has two food courts at opposite ends of the mall. Even if she had never been there, an agent was sent to check for Mike. Someone would have mentioned there being a second food court.
After capturing Simon driving the ambulance, Michael takes Simon's handgun from him. When Management arrives, Michael racks the slide of the handgun. No round is ejected. The weapon had already been fired shortly before, and therefore there would already have been a round chambered, making it unnecessary to cycle the action, and the currently chambered round would have been ejected. Common error in TV and movies inaccurately depicting operation of a weapon for dramatic effect.
When the helicopter explodes, Management falls to the ground. Management suddenly has a full head of hair and is obviously a stuntman.
