Character mistake: Frank calls a box wrench a ratchet wrench when he's working on the car with Adele's son. (00:28:28)
Suggested correction: It looks like a ratchet wrench and Frank could have called it a socket wrench and still been correct - the terms are used synonymously. While I'm no expert on wrenches, my dad had all types of tools and I knew the different types of wrenches, saws, hammers, screwdrivers, etc. before I was a teenager. "Box-end" wrench refers to the shape of the wrench (box or ring), distinguished from "open-end." So, a ratchet wrench has the box-end shape and Frank correctly identified the ratchet wrench.
Character mistake: No bank would spread out the money on the counter during a withdrawal, especially if it were a significant withdrawal and closing of the account, as when Adele tries to get money for their leaving to Canada.
