Colin Farrell's turned over a new leaf, because this summer his latest affair is with the box office.

Having startled us all with his so-perfect-it-hurts portrayal of a megalomaniac boss in 'Horrible Bosses,' last month he also reminded us that he's a verifiable screen hunk in 'Fright Night.'

Now the young Irish actor is exploring future roles, both real and aspirational.

"I’d love to play a fighter," he told The Irish Times this week. "I have no illusions. I am not saying I have the heart that a lot of those fighters I’ve seen over the years have.

"But it’s something to do with my fascination for the levels of discipline and focus that they have. But, actually, I’ve never really been great about having a list of things I want to do."

Farrell's performance in Irish playwright Martin McDonagh's 'In Bruges' reminded the public - and crucially Hollywood casting directors - what an offbeat but completely hypnotizing screen presence he can be.

McDonagh's oddball characters have allowed Farrell to demonstrate he's much more than a pretty face, and the low budget hits have kept him in the A-leagues. So it's no surprise he's signed on for McDonagh’s next film, 'Seven Psychopaths.'

"Even the title is good writing," he told the Irish Times. "It’s a brilliant script. I long to get back on set and get back into his world – that amazing headspace."

Concerning his love for his home land Farrell is candid: "I do have two places that knock on the door of my heart,” he says. “Those two places are LA and Dublin. There was a time when I felt that my heart was torn in two. Now I don’t. I have the boys in LA. Two of my sisters live there. In Dublin I have my mother, my dad, my brother and all my other rellies. I miss all my mates, but I am constantly in touch. Life goes on."

"I will be home in December," he adds. "I can’t wait. I know from talking to my mates that life is very tough. But there’s something in Ireland that transcends the emotional or economic pinch. The fortitude of that island and the strength of that island is very much part of who I am."
