Continuity mistake: During one of the scenes when Brad Pitt arrives home, he is driving a Lincoln Town Car, not his Cadillac. This is the car that he doesn't get until later, when he steals it and drives home during the scene when they crash the cars into each other at the end of the driveway.
Question: Sort of a technical question, but what type of camera was used to make this movie, film or digital? Also, there seemed to be a lot of shots made with a hand-held camera, was there any reason for this other than the "cool" factor of the camera moving through the shot? (The hand-held shots are generally the shots that are more "shaky" and such).
Question: After John and Jane killed all those people, wouldn't their boss send more people after them? And why don't the Smiths fear/anticipate/react to this fact/possibility? Is it me or does it seem the only way they could have a happy ending is die or they have to kill the boss and destroy all their records (Which they would probably die trying).
