True Detective co-stars Colin Farrell and Vince Vaughn put their on-screen interrogation skills to the test on Jimmy Fallon's US chat show.
The pair are the leading lights in the second series of the hit show that will air in the US on Sunday night and Sky Atlantic on Monday at 9pm.
In the game, each player was given an envelope and had to read out what was inside, with the other two players deciding whether their confession was true or false.
See how Farrell's ploy of twitching before he even read out the letter worked out below.
True Detective is back – but back where? The enthralling first series of this HBO drama, written by Nic Pizzolatto, directed by Cary Fukunaga and starring Matthew McConaughey and Woody Harrelson as a deliciously mismatched pair of cops, slouched across the badlands of Louisiana like something escaped from a swamp. Its potent, pungent story of myth and murder unspooled against a backdrop of gnarled mangroves, rotting clapboard churches and sweaty flophouses. And, at least until a misfiring finale, it did almost everything right, earning a devoted audience, rave reviews and a clutch of awards.
