Diana's film of Giancarlo is an exact replay of the movie's scenes. This film, supposedly shot from an air-conditioning vent, includes a shot from the other side of the room of her and her cameraman being discovered.
In the mall cooking scene, Jackie "dices" the rolled egg very sloppily and the egg is in scraps. The next shot of Jackie throwing the egg to Miki, for a split second you can see the rolled egg chopped perfectly.
In the scene with the Pepsi truck accident, Jackie is fighting off thugs. In one shot people are walking by on the sidewalk and seem not to care about the fight or the accident, but a few shots later a large crowd has appeared on the sidewalk to watch the fight.
When Diana is attacked in her house while she is wearing only her white bra and panties, the label in her panties is sticking up. When she later runs down the street it is tucked inside. She could not have noticed, nor redressed it in the meantime.
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.
In the scene where Giancarlo offers half a million dollars to the Demons in exchange for the return of his cocaine, later on when the gunfight breaks out and the briefcase is knocked open, and also later when Giancarlo is carrying the money out in his arms after the gunfight, we can see that it was only filled with $1 bills.
