‘Line Of Duty’ star Adrian Dunbar has raised the prospect of the hit police drama returning as a film.

Dunbar, who plays Superintendent Ted Hastings in the show, said he does not know what writer Jed Mercurio is planning with the format, but he thinks a big-screen outing could be a possibility.

The 63-year-old expressed doubts about whether another full series is in the offing, but said an announcement on the show’s future could be made by the end of September.

Whatever the form, Dunbar said he would love to be reunited with Martin Compston and Vicky McClure, his co-stars in the AC-12 Anti-Corruption Unit.

Previous series of Line Of Duty have been filmed in Belfast.

“I think there might be something, there’s something going on out there regarding Line Of Duty,” Dunbar told the PA news agency.

“I’m not sure what shape it’ll take ... somebody was talking about possibly a film or maybe, you know, two 90-minute [episodes] or three episodes.

“I’m not sure you’d get a full series. But I think there’s still an audience out there to see the three of us back together again.

“It certainly would be nice to get back to Belfast, where we’ve always had good fun.”

He added: “It depends what they come up with. I think we’ll hear something shortly about it. I’ve got a feeling that before September is out, we might hear something about Line Of Duty that we can tell people.”

The sixth series of the police drama was a ratings success for the BBC last year, with its dramatic finale revealing the identity of the mysterious corrupt officer, ‘H’.

Dunbar spoke to PA in his home town of Enniskillen where he was participating in the Happy Days literary festival dedicated to the work of Irish playwright, Samuel Beckett.
