Jason Watkins, Lee Ingleby and Royce Pierreson also report to AC-12!

Actress Thandie Newton (Westworld) is confirmed to guest lead in the fourth series of Jed Mercurio’s hit BBC One (originally BBC Two) drama, Line Of Duty.

Other new cast additions, who will be joining series regulars Martin Compston, Vicky McClure and Adrian Dunbar, are Jason Watkins (Love, Nina), Lee Ingleby (The A Word) and Royce Pierreson.

Thandie will play DCI Roz Huntley, AC-12’s new antagonist with Roz and her team in the thick of a career-defining case, Operation Trapdoor.

Under intense pressure to catch the culprit and prove herself to her superiors, and facing conflict with her colleague, Forensic Coordinator Tim Ifield  (Watkins), it’s not long before AC-12 decide to probe her handling of the investigation. A mother of two and wife to husband Nick, (Lee Ingleby), Roz will do anything to stop her life unravelling. Anything.

Determined to uncover the truth, Detective Sergeant Steve Arnott (Compston), Detective Sergeant Kate Fleming (McClure) and Superintendent Ted Hastings (Dunbar) must work together to tackle their most devious opponent yet. They are aided by PC Maneet Bindra (Maya Sondhi) and newcomer Detective Constable Jamie Desford (Royce Pierreson).

Thandie Newton says: “I watched the last three seasons of Line of Duty with breathless admiration for its creators, both behind and in front of the camera. I couldn’t be more thrilled to be joining them now.”

Vicky McClure says: “Such exciting news to have Thandie on board. I’m really looking forward to working with her and getting back to Belfast with the team.”

Martin Compston says: “I’m delighted to be heading back to Belfast with the rest of the AC-12 cast and I’m looking forward to once again trying to do justice to the fantastic scripts Jed Mercurio has written. It’s a testament to how well Line of Duty has done last few years that we can attract someone of Thandie Newton’s calibre to the show. It’s great to have her on board.”

Adrian Dunbar adds: “I am thrilled and excited about the new series, as we get the team together for another heart-stopping journey with AC-12. It’s going to be great seeing old friends and making some new ones.”

Creator, writer and Executive Producer Jed Mercurio says: “Thanks so much to the fans who’ve made Line of Duty such a success. Thanks to the BBC for all their support in making the series. It’s incredibly flattering we’ve been able to attract such amazing talent as Thandie Newton, Jason Watkins and Lee Ingleby to join our brilliant regular cast of Martin Compston, Vicky McClure and Adrian Dunbar. We’re all looking forward to tormenting the nation with ever more diabolical plot twists!”

The fourth series will be its first to air on BBC One after becoming BBC Two’s highest-rating drama series ever since current measuring system began in 2002. A fifth series has already been commissioned.

Line Of Duty is made by World Productions. Series 4 begins filming in Belfast in September 2016.
