Picture this. You’re in a supermarket in Las Vegas, on the edge of Sin City’s party strip. Then who should you see in the queue but Steve Arnott from Line of Duty – although instead of nicking bent coppers, he’s stocking up on a few groceries. You’d be forgiven for assuming you were still feeling the after-effects of the previous night’s tequilas, but you’d be wrong.
It’s a scene in which Martin Compston, who has played Britain’s favourite waistcoat-wearing anti-corruption officer in Jed Mercurio’s blockbuster police drama since 2012, has inadvertently starred a few times. “You’re standing in the checkout lines and they’re doing the double, the triple and then the quadruple take, trying to work out if it’s you, because you’re standing there in shorts and flip-flops,” he says. “And also they hear the Scottish accent as well, it’s confusing to them.”
