Say what you may about Colin Farrell, he's never short on surprises. Here he is on Jimmy Fallon with True Detective co-star Vince Vaughn playing 'True Confessions', where they take turns confessing to a random truth. 

We're not surprised that Colin was in fact brought in for suspected murder when he was a teenager. We're even less surprised by his alibi (around the 3:50 mark)... What we're most jarred by is his quite amazing Robert Durst impersonation... But then his very charming 'good cop' routine pulls us right back in. It's a rollercoaster man, A ROLLERCOASTER.

It's also nice to see Colin and Vince getting to have a laugh given True Detective tends to be less than cheery...
