When Kurt Sloane (Alain Moussi) and Master Durand (Jean-Claude Van Damme) gets arrested. They both get cuffed by the officers, however in the next scene, you can see the back of Sloane (Alain Moussi) holding on to his hands, instead of being actually cuffed.
In the scene were they are fighting on top of the elephant, you can tell that while they are on top, the elephant is fake. But to make it seem real during the fight, they keep cutting to a real elephant between scenes.
When Sloane does a back-flip kick to Storm, this is shown twice from different angles. The second time it is obvious that there is no physical contact and that Sloane's kick isn't even directed towards Storm.
When Tong Poe gets kicked by Sloane while standing on all four, it is obvious that this is just a "forced perspective" and that they are actually several meters apart, since Sloane appears to be much smaller than Tong Po.
In the scene where they are escaping from prison and jumping off the second floor into the street (approximately 59 minutes into the film), the stunt crew is clearly visible on the ground with the landing pad for the jump as they climb onto the top of the police truck. When they jump down off the truck, the edge of the pad comes up into the frame.
