Visible crew/equipment: Near the end of the story, there's a scene with several of the key characters all out on a sidewalk, summing up their experiences. On the frame of an open door in the near background can be seen the shadow of the microphone boom.
Visible crew/equipment: Upon landing in the U.S., the scammers exit their jet. As the action proceeds, on the plane's tail can just barely be seen the logo of the Indianapolis Colts football team. (In fact, the plane used for the movie does belong to the Colts.)
Continuity mistake: The children's' aunt makes an urgent phone call to the police from her home living room. It cuts away to a pizza parlor, to which she's dialed a wrong number. It cuts back to her, and suddenly she's in her car, on a cell phone, apologising for the mistaken call.
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.
