Other mistake: While one of the gunmen searches the bathroom, Castillo is shown hiding near the ceiling by pressing his hands and feet against the walls. He then jumps down onto the floor and sneaks up behind the gunman and stabs him. There was no way the gunman didn't hear Castillo land on the bathroom floor; Castillo was directly behind him, and no other sounds were made. (00:42:50)
Other mistake: When Laura stabs Castillo in the back, she pulls out the knife, but no blood can be seen on it. (00:39:08)
