Change of fighters?
OK just one (quite major) editing mistake.
In the fight leading up to the final climax, who am i (jackie) has a fight with two hired people on top of the building. After he has a fight with the first guy the second guy has a go. you will notice he is quite tall and has a blue shirt with white spots under a waistcoat. for a second of the fight as he does a jumping kick over an air vent. If you notice it turns to a slightly shorter fatter guy wearing a red shirt with waistcoat, he only comes in for a second whilst doin this kick, then the camera changes and it goes back to the tall guy and the fight continues as normal from then on.
I think this is quite amusing if you havnt noticed it already since the least they could do is sort him out with the same clothes.
