Revealing mistake: During the car smuggling scene where Van Damme is fighting on the boat one of the thugs slides/falls against the side of one of the cars. If you look closely, you can see the side view mirror on the car is made of rubber.
Revealing mistake: After Alex has crushed Zhang's hand in the cogs on top of the crane we see that while covered in blood there is no other damage to Zhang's hand. He even manages to move it and his fingers when in fact all the bones in his hand should have been crushed and the muscles and skin torn leaving his hand in tatters and unusable.
