Money matters everywhere, of course, but one of the differences between truly, exactingly ordered period pieces and their more lax brethren is in the use of American currency. Twenty dollar bills, with a larger Andrew Jackson on the front, were redesigned in 1998 and 2003, so when you see an ATM spit out in new currency in a movie set in the 1980s, it's a foul, but chiefly on whom? The script continuity person? The production designer? The director? There's enough blame to go around, I suppose.
