In anticipation of the second-season premiere of True Detective this Sunday, Jimmy Fallon invited Colin Farrell and Vince Vaughn to the Tonight Show on Thursday. Not just for a traditional late-show chat, though. The host sat both actors down at an interrogation table, strewn with cigarettes and coffee cups, and invited the co-stars to say something about themselves that was true or false in a game called True Confessions. Fallon, in turn, and the actor not confessing, had to double-team the “suspect” in attempt to determine whether his statement was actually true. It seemed like the segment would be all fun and talk-show games, until Farrell alleged the following.

“When I was a late teen, I got brought in for questioning as a suspect in an attempted murder,” said the Irish actor.

While Fallon and Vaughn seemed to initially both doubt Farrell’s claim, he kept providing additional convincing details.

“I saw a photofit of the guy who actually did the crime, and it looked remarkably like me,” Farrell said, “and for a second, because I had had a blackout that night, I wondered, ‘Could I have done such a thing?’ . . . [The suspect] had bushy eyebrows, a mole on his face, spoke even in two dimensions with an Irish accent.”

Farrell ended up revealing that the insane anecdote was actually true, before providing more background.

“I was supposed to bring my mother to the airport. I was in Sydney, Australia, and I was pulled in by the cops. They showed me a photofit of the pencil sketch of the guy that had attempted to murder this other gentleman. [He] had beat him up and left him in his apartment, and set the apartment on fire, and had split, thereby leaving the guy to burn to death. [The police] showed me that picture and said, ‘What do you think?’ And [the sketch looked so much like me] that I said, ‘I think I’m in trouble.’”

In case you are wondering, this is how Fallon and Vaughn reacted to this story.

“I was terrified,” continued Farrell. “I was there for about six hours. And then, thankfully, a friend of mine had kept a journal. And that particular night at that particular time, we were at a party on the other side of town doing ecstasy.”

In a 2004 interview, Farrell alluded to the 1994 incident but did not provide any of the colorful details he shared Thursday with late-night viewers.

As if this story was not mind-blowing enough for one segment, Farrell also broke into an uncanny Robert Durst imitation, complete with uncontrollable blinking.

Even if this season of True Detective does not live up to the first, at least Farrell and Vaughn will have topped last season’s stars Matthew McConaughey and Woody Harrelson in the promotional department.
