English actor Idris Elba and English actress Naomie Harris

Production on the two-part Luther television event began this week, with Idris Elba returning to his iconic role of Detective Chief Inspector John Luther, BBC America announced.
"Pitted against his most chilling adversary yet, haunted by the ghosts of his past and hell-bent on retribution, he's drawn into a terrifyingly complex case that pushes him closer to the edge than he's ever been," a synopsis said.
Written and created by Neil Cross and directed by Sam Miller, the special will also star Rose Leslie, Laura Haddock, Darren Boyd, John Heffernan and Patrick Malahide, with Michael Smiley and Dermot Crowley returning as Benny Silver and DSU Martin Schenk respectively.
"It's very exciting to have Idris Elba back as DCI John Luther and to be in East London shooting the show's fourth installment," executive producer Elizabeth Kilgarriff said in a statement Tuesday. "Neil Cross has pulled out all the stops to make this the biggest, scariest story yet and it's a privilege to welcome such a glittering array of acting talent to our already stellar cast."
The crime thriller Luther ran for three seasons in the United Kingdom from 2010-13. It was later broadcast on BBC America in the United States.
