Colin Farrell
Colin Farrell tries to give the impression of being a working-class Dublin boyo – but in fact he comes from the posh Dublin suburb of Castleknock.
Some have fallen for the image he projects – the on-line magazine, “Askman,” for example, once wrote that Farrell is “the kind of guy you want to knock back a few pints with. He oozes working-class heroism.”
His father Eamon, was a former soccer player with an Irish club called Shamrock Rovers, and currently runs a health food store in Dublin. He has said that his mother, Rita, collects newspapers clippings of him for her scrapbook.
Although his accent makes him sound like someone who grew up in a tough Dublin neighborhood of Dublin, Farrell attended two elite private high school, Castleknock College and Gormanstown.
As a young man, he auditioned for the Irish boyband, Boyzone, who would go on to sell almost 20 million records.  He went to an acting school in Dublin and an agent first noticed him in a 1997 low-budget feature, “Drinking Crude.” That helped land him a role as Danny Byrne in a British-made TV series set in Ireland called “Ballykissangel.” Fittingly, Farrell played a bad boy from Dublin, who had come to live in Ballykissangel, a rural village of in Co. Kerry.
Two years after first appearing in Ballykissangel, and Farrell got his really big break: a starring role in the Joel Schumacher film, “Tigerland.”
And the rest, as they say – the drinking, womanizing, crazy stalker ladies and leaked sex tapes – is history.
Gabriel Byrne
Gabriel only went to acting classes at the age of 29 because he wanted “something to do in the evenings’” - and to pick up women.
He studied archeology at University College Dublin, but had little love for the place. He once telling students at rival Trinity College that the university felt like a grey airport, waiting for a plane that never arrived landed. Prior to that, “The Usual Suspects” star had tried his luck as a teacher, a clerical student and a cook.
The acting classes paid off: he secured himself a role an Irish television soap opera called The Riordans” in 1978. Byrne, became a fans’ favorite in the hugely popular soap. That would be followed up by a Riordans spin-off called “Bracken,” in which Byrne played a young farmer in dispute with an older, greedy landlord.
His big movie break finally came in 1990, in the Coen brothers's “Miller's Crossing.”
Liam Neeson
Liam Neeson was born a Catholic in Ballymena, an overwhelmingly Protestant town in Northern Ireland. Ballymena is the home of Ian Paisley, the Protestant fundamentalist preacher and unionist leader. At the age of 13, Neeson used to sneak into Paisley’s church hall in Ballymena to hear him preach.
"He had a magnificent presence and it was incredible to watch this six foot-plus man just bible-thumping away,” Neeson told the BBC. “It was acting but it was also great acting and stirring too.”
Neeson was so captivated by Paisley that he decided to go into acting himself.
His father was a caretaker (a custodian) at a school, while his mother was a cook. Neither of them initially approved of him wanting to become an actor.
One day in 1975, he successfully auditioned in Belfast for a place at the Lyric Theater. After a time there, he went to Dublin for various roles in a theater called the Project Arts Center. The British director John Boorman spotted him there, which lead to his role in “Excalibur.”
While working on that film, he met and began dating Helen Mirren, and eventually moved to London.
He then nabbed a role in Sam Raimi’s “Darkman.”
His real breakthrough came in the 1990s with his starring roles in the classic films “Schindler’s List” and “Michael Collins.”
