We ran into Michael K. Williams (or as he will forever be known in the hood: “Omar from the HBO program The Wire“) on the streets of Brooklyn yesterday, which is how we know he has wrapped shooting on his black cowboy epic with Idris Elba, Erykah Badu and Jeymes Samuel (at least for the moment) and is back in a N.Y. State of mind. Or maybe that should be “Brooklyn Zoo” state of mind, because MKW stopped by Power 105′s Breakfast Club show this morning to chop it up about his forthcoming portrayal of Ol’ Dirty Bastard. Williams does not hesitate to go deep, explaining how the ‘dark state of mind’ necessary to do the character of Omar justice spilled over into personal life, including a lot of “drinkin’ and druggin’.” Although he obviously has some regrets, he says the experience gave him the tools to play O.D.B. without “going too far.” Of course there’s a lot more details about the film, which is titled Dirty White Boy and focuses on the last two years of the rapper’s life, his struggle with mental illness and his relationship with his manager Jared Weisfeld–and the reaction of some of the other Wu members. Watch the full 20-minute interview above.
