British actor Idris Elba is set to take the wheel of a new documentary about race car driving for the BBC. The Wire star will front a two-part series, Idris Elba: King Of Speed, in which he will visit racetracks around the world to get to grips with the dangerous sports' beginnings. He will be joined on the road by The Cannonball Run writer Brock Yates. The documentary will air later this year (13). It is the latest career change for Elba - as well as acting he is also enjoying work as a club DJ.
