LINE of Duty's Martin Compston left viewers surprised when they heard his real accent on The Nightly Show.
The actor - who plays DS Steve Arnott - was on the ITV chat show to talk about the popular drama.
But those watching were confused when Martin, 32, didn't sound like Steve, at all.
Another echoed: "Freaked out by DS Arnott having a Scottish accent! Who knew?
A third said: "Watching @martin_compston on #TheNightlyShow and honestly I had no idea he was putting on an English accent for 4 series of #lineofduty."
"Love hearing @martin_compston's natural accent #thenightlyshow", said another fan.
A different account was shocked: "Wtf?? I didn't know @martin_compston was Scottish! #thenightlyshow #lineofduty."
When he was first discovered after being left for dead, the prognosis did not look great.
The next episode of the gripping crime drama - which recently made the move from BBC Two to BBC One - continues on Sunday at 9pm.
