Episode 12.9. Idris Elba still using his English accent - mostly.
Why wouldn't he use an English accent? He's British.
Yes but he didn't in later American parts, such as The Wire.
So? Just shows he is adaptable and a very good actor. Have you seen any of the Luther series? He's also being considered for the next James Bond. Can't wait.
Who did he play? Its not ringing a bell for whatever reason.
