Kelly Macdonald has been named as the lead guest star in the next series of BBC One’s Line Of Duty.
Macdonald, best known for her roles in Trainspotting, Boardwalk and Giri/Haji, will play Detective Chief Inspector Joanne Davidson, the senior investigating officer of an unsolved murder whose unconventional conduct raises suspicions at AC-12.
Filming begins next year with series leads Martin Compston, Vicky McClure and Adrian Dunbar all confirmed to return.
Line of Duty writer and showrunner, Jed Mercurio, said: “We’re honoured that Kelly Macdonald will join Martin, Vicky and Adrian in series six of Line Of Duty. DCI Joanne Davidson will prove the most enigmatic adversary AC-12 have ever faced.”
Simon Heath, CEO and Creative Director of World Productions, added: “The Line Of Duty team have always been huge fans of her work, so we’re thrilled Kelly has agreed to join us this series to pit her wits against AC-12.”
Piers Wenger, Controller of BBC Drama, said: “We’re delighted that Kelly Macdonald is coming on board for series six. She’s one of the UK’s most versatile actors and we’re excited for viewers to see what Jed’s scripts have in store for her when she joins the Line Of Duty team.”
