Continuity mistake: In the scene where the old oriental woman is taking Chelios' temperature the sheet is low enough that you can plainly see the battery pack sitting on his stomach. As she walks out two guys come in to check on him and they have to pull the sheet back to reveal the battery pack. (00:02:25)
Revealing mistake: When Vang and Chev are running and about to jump the fence into the power station, look in the fence and you can see the handy foot holds that the actors use to go over the fence.
Continuity mistake: When Chev is about to go into the strip club, he is looking at the Asian girl, in the next shot his entire position has changed instantly.
Revealing mistake: When the Ferret's goons are dragging Chev behind the speed-boat near the end, when the one henchman (with all the tattoos) urinates on Chelios, you can see he is holding a small device/hose that is spraying the fake urine out.
Continuity mistake: When Eve pushes Chev down the stairs at the horse track, we can see there are more seats underneath them. But they fall over the side and onto the track (close to the wall). In the next few shots they start to have sex, and when the camera pans out they are in the middle of the horse track without ever getting up.
Chosen answer: Nothing has been said and no indications are given as to what is in the cooler.
