Just a comment on New Orleans accents...
An earlier reviewer noted the following: "This film, could have been shot in New York, or another Northern big city because it presents us with characters that speak more like "broklynese" than maybe a Southern accent one might hear in that part of the country." There was also another comment along these lines from an English reviewer.
Many people in New Orleans do, in fact, sound "broklynese". I have never found out why. (It's mentioned in "A Confederacy of Dunces" by John Kennedy Toole.) I always appreciate movies taking place in New Orleans that include this detail, as this one did. Too often it's just the Hollywood version of the standard Southern accent.
