BBC Release Trailer For Line Of Duty Season 5 And It Looks Intense

Line of Duty debuted a teaser trailer for a new series, after Sunday night's Bodyguard finale, confirming the BBC drama will be returning next year.

Despite only being 16 seconds long, the trailer got fans seriously excited when they were treated to a surprising amount of detail about the new series.

It also teased a style change for DC Arnott (Martin Compston), who was spotted sporting a well-trimmed beard.

Superintendent Hastings (Adrian Dunbar) is also seen detailing a new case to Detective Sergeant Fleming (Vicky McClure).

"AC-12 is being met with an institutional cover up," he explains. "We need to get to the root of it."

She then responds: "The root being what, sir?"

Finally, the video cuts to a black screen confirming that the drama will return in 2019.

In August, the BBC announced that filming for the latest series of Line of Duty was underway when it tweeted a group photo of Vicky McClure, Adrian Dunbar and Martin Compston.

The trio looked pretty happy to be back together again.

Line of Duty was created by Jed Mercurio, who also created the latest BBC hit drama Bodyguard.

Chatting to Holly Willoughby and Phillip Schofield on This Morning, Jed explained: "We're just beginning that conversation with the BBC so we know that people out there are loving series one and that there would be an appetite for series two, but we'll just have to wait and see.

"A lot goes into setting up a production and none of those conversations have taken place yet which would allow us to facilitate that production."

And speaking on the set of The Bodyguard, he added: "I really do love doing returning series, so if this is successful, and people stick with it, then it would be great to do more."
