Los Angeles, Dec 19 : Hollywood star Colin Farrell, who plays an addict in his latest movie Ballad of a Small Player, said he's drawn to roles exploring the dark side of life because all humans experience bad times.

He said: "I have mad moments of joy in my life and joy in work and joy with my kids. But Iâ??ve always felt that the common denominator in regard to experience as humans is pain. The one thing weâ??ve all felt, really, is pain. I put fear and uncertainty under that banner.

"Not everyone, sadly, has felt joy. And thatâ??s a great tragedy. But Iâ??m fascinated with pain. Every single act of aggression or violence has its root in pain that has become personalised," he shared, while speaking to Jessie Buckley for Variety's Actors on Actors series.

Despite his own past struggles with addiction, the star said he didn't draw on his own experiences for his latest role because he thinks it is such a "particular" thing to go through, reports femalefirst.co.uk.

He said: "When I read 'Ballad', it was a character that .. there was no reason, no backstory given in the script â?? he just was somebody who was drowning beneath this agitated pain. I couldnâ??t really figure it out when I read it. I concocted whatever fiction for myself in regard to backstory. But I just wanted to explore it.

"Iâ??ve had a history of addiction and bits of depression and anxiety â?? the whole smorgasbord of human frailties as well. Inevitably, youâ??re always drawing from your own personal experience, but I didnâ??t feel like I was drawing from the experience I had with addiction, which was very particular.â??

"The addiction is just a consequence of certain things unanswered or certain uncertainties that are too fearful to even comprehend. So you pretend theyâ??re not there. And you pretend that you have answers when you donâ??t have any business having an answer at that particular point. You just have to sit in the uncertainty of it all â?? sit with the agitation and the sorrow and the fear of that."

The star, whose eldest son has Angelman syndrome, a rare genetic disorder, knows his work is a "privilege" in the way it allows him to explore all his experiences and feelings, but he is also aware that it can't change his life in a significant way.

He said: "The permission to be overwhelmed is a huge thing to give to each other, to give to our kids. Iâ??m so aware of the amount of privilege that Iâ??ve experienced in my life and what rare air I fly in regarding what I do for a living. But at the end of the day, thereâ??s nothing I can do in acting that can make James, my oldest boy, talk or have language."
