There are so many things worth pointing to here, but here's how show creators David Simon and Ed Burns created Omar Little, everyone's (including President Obama's) favorite gay stick-up man played by Michael K. Williams:
David Simon: Omar was a combination of various guys Ed had used as informants or knew. He was an amalgam.
Ed Burns: The Omars of the world are warriors, too. They’re the guys who despise the drug dealers. He’s the rebel, and he goes by his own code. When I was a cop, you’d look for guys like this. If you’re sticking up drug dealers, you have to carry a gun. And if you’re carrying a gun, I can lock you up. Pretty simple math. Once I lock you up, then we sit down, and we start talking, and then we start going to the State’s Attorney’s office, going to the judge, making deals. So I knew a lot of Omars, and Michael K. Williams did a phenomenal job.
Reading this stuff is like talking to your parents years later about all the behind-the-scenes family drama you never knew was going on at Thanksgiving as a kid. Wait, that might sound painful, but reading this oral history is nothing of the kind. Highly recommended!
