Right on both cultures, and the accents therein. Your US examples are right on. Although for the Southern accent, I might have chosen "If ya go to a family weddin' to look for a date, you just might be a redneck." (Though the majority of Southerners are not redneck at all.)
I lived in Hertfordshire for a year at school and have made a bunch of trips to London, but never ever have I heard an Englishman or woman say "Pip-pip".
Hahaha!
Just goes to show...I liked the original "Cape Fear" better.
That may be because I was born in the next state down and, to me, Mitchum's accent was the more subtle while De Niro just sounded like most Yankees trying to talk "Southern". That may play well in Peoria but, it ain't gonna fly in Savannah.
Oh, well...both overall good movies.
It's funny but both you and ssjones said the same thing, that De Niro's accent sounded wrong. I didn't notice that at all, probably because my English ear couldn't recognise the nuances.????????
