Line of Duty star Martin Compston said that the cast knew that there was one more season left for the show, saying that he is "excited" for it to "go out on a high".
Compston made these comments while promoting his new Paramount+ thriller series, The Revenge Club, which looks at a divorce support club plotting revenge.
Speaking about plotlines for the new season of Line Of Duty, the actor said that he has been sworn to secrecy about what this series will bring, but he added that this remains part of the show's appeal.
"I don't think people want to know," he said. "It’s kind of weird. People always go, 'Is it this?’ and then say ‘Don’t tell me. Don’t tell me’.
He continued: "I think people love the surprises and that’s one of the big things about the show, the twists and turns is what makes it appealing".
"I definitely think The Revenge Club is so, so bingeable, and it’s right that this drops all at one time, because you can blast through it.
"But I think Line Of Duty is one of the kind of last staples of a show where you leave it the week in between", the actor added. "I don’t think we’ll ever drop all the episodes because it is that water cooler thing where people talk about our work during the week, come up with theories and build the suspense.
"I think the secrecy is a big part of it".
Compston went on to explain that it was more than the storyline which back into the show.
"I think you need distance from it. The other [series] went so mental that we kind of all needed a break from it for a bit, but I think we’re pretty sure we had one more in us".
"From a selfish point of view, we’re all really close, we’re all really good pals, so we genuinely have a really good time working together", he explained. "We’ve been lucky the last few times, with The Revenge Club and stuff because you’ve got such an amazing team and it’s such a joy to film it".
"But Line Of Duty can ruin it for other jobs because you’re just with your pals all the time".
Filming season seven of Line of Duty also coincides with next Summer's FIFA World Cup in America, a tournament which Compston's beloved Scotland qualified for.
In 2021, the actor was spotted in a clip with went viral of him pausing filming of Line of Duty as he celebrated Scotland qualifying for the Euros and shouting 'Come on Scotland' around the set.
Ahead of next year, Martin Compston hopes that similar clips could be shared next year.
"I’ll be filming Line Of Duty so maybe you’ll get another one of them," he said. "But I’m definitely going to try and get to a game. It’s been a long, long time coming".
"I can’t miss it all. I’ve got to get to one game. I’ve got to experience Scotland in the World Cup, because who knows when it come around again".
He added: "Look, Brazil is the glamour game, I mean, you could potentially get a scuddin’ there".
"Playing Brazil in Miami in the World Cup, I don’t think it gets much better than that", Compston said..
"Morocco is a really tough game. That’s probably toughest", he added. "And Haiti, no doubt will be a tough game, but if you don’t win that, I don’t think you deserve to go through.
"I think we’ve got quite lucky. I mean, it’s a tough group, but we’ve got really lucky the way it’s been drawn with Haiti first.
"So if you get three points on the board at first, and then you think, we just need one from the second two, four will get you through".
