Williams was best known for playing Omar on 'The Wire' and Chalky White on 'Boardwalk Empire.' In 2008, Williams told Terry Gross the story behind the scar on his face and his background in dance. In 2016, he reflected on his lucky breaks and what it was like to leave Omar behind. "When 'The Wire' and the character of Omar ended, I had zero tools, personally speaking, in how to deal with letting that go. ... I didn't equip myself with the tools of how to wash that off my psyche." Williams died Sept. 6 of a suspected drug overdose.Also, critic David Bianculli reviews the new reboot of Doogie Howser, M.D.
