My favourite "movie coin anachronism" is from the movie "Troy", where they place coins on the eyes of the deceased Hector. They get plus 10 points for referencing the obscure ancient Greek custom about "paying the Ferryman" for the departed with two obols placed on their eyes. They get minus 1000 points for not realising that the Trojan Wars allegedly happened around 1200 BC - which is about 600 years before coins were invented. If the Trojans had believed in the "two obols" tradition (which they probably wouldn't have, since they weren't actually "Greek"), they'd have used "real" obols - the iron sticks the Greeks previously used for money before they invented coins.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
