Luther season 5 trailer: Idris Elba and Ruth Wilson return in brutal promo

The trailer for the forthcoming fifth series of Luther has been released ahead of its premiere this Christmas.

It was announced in June 2017 that series co-creator Neil Cross had signed up Idris Elba to return as the grizzled detective for four brand new episodes of the crime series following its apparent “climax” in 2015.

But sure enough, DCI Luther is back in a trailer that’s capped with a blink-and-you’ll-miss-it cameo from none other than Ruth Wilson’s fan favourite, Alice Morgan, which you can watch below.

Other returning cast members include Dermot Crowley, Michael Smiley and Patrick Malahide as DSU Martin Schenk, Benny Silver and George Cornelius.

New recruits include Wunmi Mosaku, most recently seen in End of the F***ing World, and Cold Feet star Hermione Norris who’ll play psychiatrist Dr Vivien Lake.

Episodes will see “the moonless shadows of London give birth to a new nightmare” as a series of killings pave the way for “devastating consequences” for those closest to Luther.

Elba has teased the show’s return promising a “classic” return to form by assuring fans: “We’re not reinventing the wheel."

Wilson, who is currently winning rave reviews playing her own grandmother in BBC drama Mrs Wilson, confirmed her appearance to The Independent earlier this year, telling fans to expect the unexpected.

“She’s definitely back for a bit,’ she said. ”She is back with a vengeance.”

The series has generated a cult fan base since it began in 2010.

Cross has made no secret of the fact that he’d like to bring the character to the big screen following the show’s success overseas. Discussing these plans, Elba added: “It’s very much in our minds, the film. I think it could be an amazing series of films.”

Luther series five will air in December as part of the BBC's bustling Christmas lineup which will also include an Agatha Christie adaptation featuring a rather different version of Poirot, played by John Malkovich.
