Well, I thought maybe it would be fun to theorize where the characteristic OW speechs come from, so I just thought I'd point out two finds I made
in Fight Club
http://www.imdb.com/title/tt0137523/
when Marla played by Helena Bonham
http://www.imdb.com/name/nm0000307/ meets jack(protagonist) in the street before they go into the diner, and she complains to him about the "space monkeys", I think she sounded exactly like a Glukkon the first time, I couldnt even tell what she was saying, so I guess this speech comes from angry americans
.
in "that thing you do"http://www.imdb.com/title/tt0117887/
when the protagonist meets Del Paxton played by Bill Cobbs,
http://www.imdb.com/name/nm0167850/ I thought he sounded a lot like a mud, I guess it makes sense since some black people have a pretty musical speech.
