Below Zero

In the beginning when the man in the poncho pulls a pistol and points it at the man who has a leg wound, clearly the magazine well is empty meaning that either the gun is empty, or has only one bullet in it (in the chamber).

Miguel hot-wired the truck to start the engine using two hands. Then after checking on Montesinos' crash on the side road, he started the truck's engine appearing to be using a key as he used one hand for it.

The end credits begin during the final scene of the film before the main credit roll.
