Lennie James has signed up to play a former heroin addict trying to stay clean and rebuild his life, in a gritty new Channel 4 (UK) 4-part drama series titled Run.

The series will also star Olivia Colman and Jaime Winstone, and tells the stories of four seemingly unconnected characters, including Olivia's single mother struggling to keep her teenage sons on the straight and narrow, and Jaime's character finding her life turned upside down when her boyfriend is murdered.

The series is currently being filmed in London.

Lennie James may not be a household name (yet), but the man stays employed, both here in the USA, and in the UK.

He's currently starring in the new BBC drama series, Line Of Duty, and may be returning to AMC's The Walking Dead in the fall.
