Olivia in new show Run

OCO Katie Leung and Olivia Colman are set to lead the cast of the upcoming Channel 4 drama Run.

The gritty four-part drama presents the stories of four unconnected people whose lives intertwine in a story of modern-day survival.

Each episode, directed by BAFTA-nominated Skins and Being Human helmer Chris Martin, will focus on a different character.

Best known for her role as Cho Chang in Harry Potter, Leung will play an illegal Chinese immigrant hoping to make a life for herself in the UK.

Colman, who recently received a BAFTA nomination for her work in Twenty Twelve, will play a struggling single parent who gets mixed up in the world of crime.

Run is currently filming in and around London.
