Line of Duty's Ian Buckells star has compared the bombshell moment in Sunday's finale to one of cinema's most iconic moments.
Nigel Boyle played Ian Buckells in the BBC hit, and was unveiled during the series six conclusion as the shadowy figure of H, a mysterious crime lord who'd plagued our heroes for all six series.
And Nigel, chatting about the big reveal, has said he went "all Keyser Soze" - a reference to 1995 classic, The Usual Suspects, in which Kevin Spacey is revealed to have been the sinister gangster all along.
As the film ends and the truth dawns on the fooled detective, Kevin stops dragging his foot and gets into a car, driven by Keyser Soze's butler.
At this moment the audience realises that the man he's been describing the whole film is, in fact, himself, and it's gone down as one of cinema's biggest and best twists.
"I remember saying excitedly to my wife, 'Buckells goes all Keyser Soze!'" Nigel recalled to Radio Times.
"In fact, I very nearly tweeted a Usual Suspects meme in the build-up to the finale. I really wanted to post that clip where Kevin Spacey suddenly straightens up and stops limping. Luckily, I thought better of it. Spoilers!"
His character Buckells had craftily shrouded the vision of his fellow coppers by acting as a "blundering fool" whom they would never suspect.
Viewers got to watch as Buckells morphed from his bumbling alias into a suave, quick-tackling gangster at the command of a vast criminal network.
"I thought very carefully about the reveal and how to handle it," Nigel shared, "Buckells needed to suddenly display more assurance and confidence. The best way to do that was through body language."
Sunday's finale has left viewers divided, with former GMB motormouth Piers Morgan expressing his disappointment with the "tad underwhelming" conclusion.
But the episode made BBC history as a record-shattering 21.8 million viewers tuned in to see how it all wrapped up.
This gave it the highest ratings for a drama since records began.
