The accent? Booke studied Strom Thurmond at length and based his accent on him.
When he died in 1994, we lost a gifted actor and great linguist.
FYI, Stetson hat factory was in Philadelphia, of all places. Had a few ancestors who worked there back in the day.
Booke was soooo funny as Boss Hogg I just had to look at him to get a laugh. Add in the accent and the mannerisms, that white suit and hat, cigar-— just hilarious and brilliantly funny too.
