Imagine Playing A Boss Hiring An Assassin

I got to do just that in a funny little film, appearing on YouTube, called "Casey Carr & Riley Joe: Brothers Forever", produced by a promising young director named Diane Forman, originally from the Hudson Valley, not far from Albany, in Upstate NY.
Currently, she lives in Crown Heights, Brooklyn, not far from Prospect Park & goes to Filmmaking School at Brooklyn College, in Midwood, Brooklyn.
I played a loud, abrasive man named Cord Elam. I was originally going to do this role in a Slow, Southern Drawl, but was told to do it in a Brooklyn Accent.
The Brooklyn Accent is easy for me, as I used to speak it at home. I don't usually speak that way anymore, except with Native Brooklynites.
The Trick to sounding like a Native is to leave out consonants in words. "Atlantic Avenue" is "Alannic Avenya" to Natives. "Flatbush Avenue" is "Flabush". "Bedford Avenue" is pronounced "Befid" & so on.
Another way of sounding like a Bona Fide Native, is to use the old time names of the Subway Lines. Never mind just the #s or letters of Subway Lines, as it sounds like you're from Boston(I do like The Red Sox, BTW). Go all out & say things like The IRT Lexington Avenue-Woodlawn to 161st Street-Yankee Stadium. When telling this to Red Sox or Mets Fans, refer to Yankee Stadium as "The Toilet."
For Coney Island, it's "Take The BMT Brighton Line to Coney Island-Stlllwell Avenya."(Ditto, Sea Beach Line).
Of course, when taking the A Train, tell people to take the "8th Avenya Subway."
I have ya tawkin' like a natif in no time.
