Can't wait to see Hollywood's Chilean miner movie... starring four white guys and 29 Latino-looking men standing in the background.— Angry Asian Man (@angryasianman) October 14, 2010
Well, yes, Hollywood does play a form of Ethnic Roulette where they can't be bothered to match the ethnicities of the actors to that of the characters. That is, you have Dustin Hoffman, who is Jewish, playing an Italian, and Al Pacino, who is an Italian, playing Roy Cohn.
This, by the way, is different from the phenomenon where they put black actors in previously white roles—I just saw Iron Man 2, and I didn't realize, when Samuel Jackson showed up with an eyepatch, that he was supposed to be Nick Fury of S. H. I. E. L. D. (I remember when Fury was a sergeant —a white sergeant, from Hell's Kitchen in New York.)
