Drawing up a list of the best Irish film actors, the criteria are unavoidably slippery. Can one great performance get you to the top? Can someone in their 20s really complete fairly against an actor who worked steadily for 60 years? Who gets to be Irish? That last question is particularly worrisome here, as two of the top seeds spent their early lives across the Irish Sea.
Most biographers make uncommitted humming noises when asked if Peter O’Toole was born in Leeds or, as he often suggested, in “Connemara”. We know that Daniel Day-Lewis, son of Anglo-Irish poet laureate Cecil Day-Lewis, was born and raised in leafy bits of London. But both took Irish passports. So we must conclude they can fairly compete both in this race and in any assessment of English film actors. Good luck keeping them out of the top five in either.
Sadly, the great Greer Garson – once erroneously credited as having been born in Castlewellan, Co Down – doesn’t quite meet the regulations (though her grandfather would be eligible for the national football squad).
A more complex question arises over whether we are assessing actors purely on their performance in films. We lean towards a qualified “yes”. It is hard, in all good conscience, to include, say, Micheál MacLiammóir, the dominant figure in Dublin theatre for five decades. We must also regretfully decline the applications of theatre and TV specialists such as Niall Tóibín, Tom Hickey and James Nesbitt.
That uncertain quality we call “stardom” is certainly a factor in our gradings. Our top-rating actor is the most incandescent Irish star to trouble the Hollywood heavens during their busiest years. The patriarchal nature of the business does mean that we have more male actors than female. That is, alas, an honest reflection of how it once worked (and still does, to an extent).
We are also obliged to skew towards more recent decades. Ireland gave the golden age many fewer actors than it gave the millennial years. The whys and wherefores of that must wait for another day.
50. Seána Kerslake (b 1990)

Galway actor made her screen debut in The Magdalene Sisters. Has subsequently starred in Ella Enchanted and Brooklyn.
Star turn: As Holly in Neil Marshall's terrifying The Descent.
46. Maria Doyle Kennedy (b 1964)

38. Jessie Buckley (b 1989)

37. Bríd Brennan (b 1955)

34. Ray McAnally (1926-1989)

28. Michael Gambon (b 1940)

Star turn: Unquestionably the Thief in The Cook, the Thief, His Wife & Her Lover.
27. Barry Keoghan (b 1992)

15. Pierce Brosnan (b 1953)
He was famous as Remington Steele before he became the fifth James Bond. The Drogheda-born, Navan-raised actor has proved a versatile post-007 character actor, too, crooning in Mamma Mia!, surviving tough in Seraphim Falls, killing in The Matador and channelling Gerry Adams in The Foreigner.
Star turn: As Trine Dyrholm's suitor in Love Is All You Need.
14. Cyril Cusack (1919-1993)
Rarely the lead, but one of cinema's greatest character actors: subtle, insidious, surprising. In dozens of films, including Harold and Maude, My Left Foot and Fahrenheit 451.
