Factual error: In the dramatic final confrontation, the husband tries to shoot Julia, only to find that the gun is empty. The problem is that slides on automatic pistols like the one used in this scene lock open when the last round is fired. The slide on this gun is visibly closed, so it should still have a round in the chamber.
Suggested correction: The gun wasn't empty, it jammed.
Plot hole: Laura rents a nice, large house, furnished with everything she needs, using a fake name, no job, no financial history, has no current bank account or credit cards or any references. She merely hands cash to the agent. She later lands a job without proof of identity, citizenship or residency (legally required), and has no references, no credible work history, or a SSN#. Laura is resourceful, but would lack the means to obtain a convincing fake identity and other false documentation.
Suggested correction: You don't have to be a citizen to work.
You do need an ID, but you don't need to be a citizen.
You need to be a U.S. citizen, a "legal" resident, or have a specific type of work visa to be legally employed in this country. You also need an identity for renting a house or apartment and a prospective tenant doesn't just hand over a large sum of cash for the rent/damage deposit without immediately getting a receipt, while standing on the porch, and not first filling out paperwork.
