In 2006, Mann joined the directing crew of The Wire's fourth season. From there, he went on to direct episodes for numerous other acclaimed television shows and is currently working on a feature film, Harriet, about Harriet Tubman, who helped free hundreds of slaves from the South after escaping from slavery herself in 1849.
