Continuity mistake: The Nigerian scammers are shown flying their private jet westward, across the Atlantic to the United States. Aerial shots above open water show the sun low in the sky behind the plane, in which case it'd be morning over the ocean. But when they land just a few hours later, it's evening and dark out. It doesn't take that long to cross the Atlantic to begin with, and flying at jet speeds westward only makes the day last even longer.
Plot hole: The entourage of scammers travel about the city at will. One of the group is an internet junkie who always has his laptop in hand and turned on. No matter where they go, in their car, in an old warehouse, etc., they always have an uninterrupted wireless internet connection.
