At the mall scene when Jackie is tossing food to the people, the fifth person he tossed to is a blond woman but before the piece of food gets to her mouth one of Giancarlo's man pulls up in front of her and catches the food with his mouth, at that moment you can see that the blond woman got behind him running out of character by moving her head, meaning that she pulled her head to the side too early for Giancarlo's man to enter the scene.
Errors in geography
Giancarlo roars at one of the cops that if they invade his property, he can "Shoot you like a dog". Another of the cops nods his head and says "He's right". The movie was shot and set in Melbourne. Gun ownership in Australia is strictly regulated, and no-one has a legal right to shoot anyone, let alone a policeman.
In the scene where Jackie leaps from the park and onto the fixed crane, swinging above where the Demons stage the kidnapping, it clearly visible that Jackie misses his mark when grabbing for the crane extension. His hands breeze right by it. But, in a following shot, you see him successfully grab the crane extension and swing down.
