WATCH: Colin Farrell Reveals He Was Once ‘A Suspect in an Attempted Murder’

Things got very real during “True Confession” with Jimmy Fallon last night.

Colin Farrell admitted he was once brought in for questioning as a suspect for attempted murder. Thank goodness he had an alibi that involved doing ecstasy, and that it didn’t amount to any serious legal troubles for him.

Along with Farrell’s True Detective co-star Vince Vaughn, the trio played “True Confession,” or rather, a glorified version of “Two Truths and a Lie” inspired by their upcoming and highly anticipated TV show.

Vaughn and Farrell play good cop/bad cop to Farrell’s suspect and things get intense. Did he get away with murder in Australia or…?!

Farrell read his first truth/lie, to everyone’s surprise: “When I was a late teen, I got brought in for questioning as a suspect in an attempted murder.”

After a frighteningly amazing Robert Durst impression, and confirming that it was in fact true, Farrell explained that in actuality, he closely resembled the actual suspect of the attempted murder.

“I was pulled in by the cops and they showed me a photo of the pencil sketch of the guy that had attempted to murder this other gentleman, had beat him up and left him in his own apartment and set the apartment on fire and split, thereby leaving the guy to burn to death,” he recalled. “And it [the photo] was me. They said, ‘What do you think about that picture?’ And I went, ‘I think I’m in trouble.

“It was terrifying. I was there for about six hours. 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.”

But still, yikes. We’re not surprised he was terrified.

Watch the rest of “True Confession” in the video above to see what the guys’ truths and lies are.

True Detective season 2 (also starring Rachel McAdams and Taylor Kitsch) premieres Sunday, June 21 on HBO.
