At the beginning, the dead guy that flew out of the boat,uses his own hand to push himself over as he is being kicked to turn over.
Near the end of the movie, when Karen (Lela Rochon) and Tommy (Rob Schneider) are tied to chairs on the cargo ship, the ship slams into a container causing them to roll around. As they do, Lela's stunt double's ropes become untied and she waves her arms around as she falls. However, in later shots, she is shown as tied up again.
(at 15:25) Marcus (Jean-Claude Van Damme) tries to stop a black van by hooking his rickshaw onto its side mirrors. The driver starts off as a Caucasian male, then becomes an Asian male stunt driver in the next shot, before going back to being the Caucasian male again.
The glass in the Skinny Freight window changes to obviously fake pre-scored glass right before the car drives through it.
When Marcus (Jean-Claude Van Damme) is sliding around on the floor of the cargo ship fighting the bad guys, at one point he gets pulled to the right side of the screen and you can see the rope that's pulling him.
(at around 47 mins) The camera for Rob Schneider's scene is visible on the building at the top left of the screen.
